Banner checker action path
Use this page when a wide image needs a publishing decision, not just a dimension readout. The fastest path is to check the final export, identify the closest banner target, route by final placement, then open the exact crop or preview guide before upload.
If the checker points to a 2560 x 1440 channel-art export, go directly to the YouTube banner safe area guide before uploading, because the center 1546 x 423 band decides whether text and logos survive device crops.
Upload the final wide export
Run checker
Start with the real JPG, PNG, WebP, AVIF, or GIF file that will be uploaded, not a screenshot or design preview.
Read the nearest banner target
Read result
Compare width, height, ratio, and file size against YouTube, LinkedIn, Facebook, and broad header targets.
Route by publishing surface
Route wide image
Decide whether the wide file is channel art, a profile banner, a cover photo, a website share image, or a marketplace cover before resizing.
Open the final crop guide
Choose guide
Move into the platform page when the checker result identifies YouTube safe area, LinkedIn overlay, Facebook cover crop, or Open Graph preview behavior.
Wide banner evidence-to-route matrix
Start with the checked file evidence, then route the wide image to the narrowest upload workflow. This prevents a 16:9 source, LinkedIn header, Facebook cover, Open Graph card, marketplace cover, or compressed preview from being resized into the wrong banner slot.
| File evidence | What it answers | Decision before upload | Next route |
|---|---|---|---|
| 2560 x 1440 or 16:9 wide export | The file may be YouTube channel art, a website hero, or a thumbnail-like wide source rather than a generic banner. | Use the YouTube safe-area route only when the final placement is channel art; otherwise choose the publishing surface first. | Check YouTube safe area |
| 1584 x 396, 4200 x 700, or very wide header | The file may be a LinkedIn profile banner, LinkedIn Page cover, or professional header image. | Confirm whether it belongs to a profile, company Page, or site header before reusing it on another platform. | Check LinkedIn banner |
| 820 x 360 or cover-photo style crop | The file may be a Facebook cover photo or broad social cover asset. | Check mobile and desktop crop behavior before placing text, logos, or calls to action near the edges. | Check Facebook cover |
| 1200 x 630 or about 1.91:1 | The file may be an Open Graph image, website thumbnail, or social share card rather than a profile banner. | Route to Open Graph size and preview checks instead of forcing the image into a header slot. | Check OG preview |
| 750 x 424, seller cover, or livestream promo | The file may be a Whatnot seller cover, show thumbnail, or marketplace promo image. | Route marketplace covers separately from social headers because listing and show previews crop differently. | Check marketplace cover |
| Wide screenshot, compressed preview, or no target match | The checked dimensions may describe a preview file rather than the original upload asset. | Find the original export or run generic file facts before resizing from a screenshot or compressed download. | Check file facts |
Wide images fail by crop, not only by size
Banner assets look simple because they are wide rectangles. In practice they are fragile: platforms crop differently on mobile, desktop, profile views, and company pages.
Start here to confirm the exported image size, then open the platform-specific guide for safe-area composition before uploading.
Banner publish readiness standard
A banner is ready to publish only after four checks pass: the file is the final export, the canvas matches the target, important content is crop-safe, and reuse across platforms has been ruled out or handled with separate exports.
| Readiness gate | Pass condition | If it fails | Next route |
|---|---|---|---|
| File evidence | The checked file is the final exported banner, not a screenshot, design preview, or compressed download. | Re-export the source artwork, then run the banner checker again. | Check final export |
| Canvas and ratio | The width, height, and ratio match the target platform closely enough for upload. | Use the aspect ratio calculator or platform guide before resizing the file. | Calculate export size |
| Crop-safe message | Names, logos, faces, and calls to action sit in the center-safe area for the final platform. | Open the YouTube, LinkedIn, or Facebook guide and move important content inward. | Check safe area |
| Reuse decision | The banner is exported separately for each platform when crop behavior changes. | Do not reuse one wide image across channel art, profile headers, cover photos, and Open Graph previews without checking each placement. | Route wide image |
Banner approval handoff matrix
Use this matrix when a banner check becomes an approval decision for a designer, platform owner, campaign manager, website publisher, client, or scheduler. It separates when a wide file is ready to approve from when it should be returned for a clearer export, crop, or platform route.
| Approval handoff | Accept when | Return when | Next route |
|---|---|---|---|
| Designer export review | The file is the final exported banner, not a screenshot or compressed preview. | The checker reads a smaller preview, wrong format, or a file that came from the wrong artboard. | Verify file facts first |
| Platform owner approval | The banner matches the intended platform target and the platform guide confirms crop-safe composition. | The file is close to a target but important text, logo, face, product, or CTA sits near an overlay or edge. | Review safe area |
| Cross-platform campaign reuse | Each platform has a dedicated export or the reuse risk table shows the crop behavior is acceptable. | One wide image is planned for YouTube, LinkedIn, Facebook, website headers, and Open Graph without separate checks. | Split platform sizes |
| Website or landing-page share | The wide file is intentionally an Open Graph card and the page metadata will expose it as a public preview image. | A 1200 x 630 image is being approved as a banner even though it belongs in a link-preview workflow. | Check OG preview |
| Client or scheduler handoff | The checker result, platform route, safe-area note, and final file name can be copied into the approval thread. | The receiving person cannot tell which platform, crop, or upload surface the file is approved for. | Run handoff workflow |
Checked banner result package
After the checker reads a banner file, package the result into a short handoff record. A useful approval note should name the checked file, the final publishing surface, the crop-safe note, the separate exports needed, the repair route if the file fails, and the approval status for the owner or scheduler.
| Package part | Include in the note | Why it matters | Next route |
|---|---|---|---|
| Checked file summary | Final file name, width, height, ratio, file size, format, and closest banner target from the local checker. | Designer, marketer, or client can see which exported file was actually checked before approval. | Run banner checker |
| Publishing surface | One final placement such as YouTube channel banner, LinkedIn profile banner, Facebook cover, website share card, or marketplace cover. | Prevents a wide image from being approved without knowing where it will be uploaded. | Choose surface |
| Crop-safe note | Short note naming the safe area, overlay, or edge-risk that was checked before approving text, logo, face, product, or CTA placement. | Reviewer can approve the visual message, not just the canvas dimensions. | Review safe area |
| Separate export list | Dedicated output files needed for YouTube, LinkedIn, Facebook, Open Graph, website hero, thumbnail, or marketplace reuse. | Campaign owner can avoid reusing one generic wide export across incompatible crops. | Split exports |
| Repair route | The next fix when the file is too small, close-shape only, wrong asset type, or actually an Open Graph or thumbnail image. | Designer gets a concrete re-export instruction instead of a vague rejected banner note. | Verify source file |
| Approval record | A copied line with checked target, platform route, crop note, owner, and final upload status. | Scheduler or client has a durable record for why this banner is ready, returned, or routed elsewhere. | Use workflow |
Banner launch decision log
Use this log after the checked banner result package is prepared. The wide file should end with one operational decision: upload, return for safe-area adjustment, create platform-specific exports, validate Open Graph, review marketplace placement, or replace a proxy file with the real source export.
| Launch decision | Use when | Record before handoff | Next route |
|---|---|---|---|
| Ready to upload | The checked banner is the final export, target match is clear, and the crop-safe message area has been reviewed for the chosen platform. | Final file name, matched target, crop-safe note, platform owner, and upload destination. | Run final banner checklist |
| Return for safe-area adjustment | The canvas matches the target but names, logos, faces, product detail, or calls to action sit near crop-prone edges. | Crop-risk area, platform safe-area guide, content to move inward, and the owner responsible for re-export. | Review safe area |
| Return for platform-specific export | One wide banner is being reused across YouTube, LinkedIn, Facebook, website hero, Open Graph, or marketplace placements. | Required export list, platform targets, reuse risk, and which files must be created before approval. | Split platform exports |
| Route to Open Graph validation | The file is 1200 x 630-style, intended for a page URL, or behaves like a website share card instead of a profile header. | Page URL, image URL, metadata owner, preview cache status, and whether the file should leave the banner workflow. | Validate OG preview |
| Route to marketplace cover review | The wide image is a seller cover, show thumbnail, livestream promo, listing banner, or marketplace product cover. | Marketplace destination, seller or show placement, product visibility, crop risk, and launch owner. | Review marketplace cover |
| Needs source-file replacement | The checked file is a screenshot, compressed preview, downloaded thumbnail, or unknown proxy instead of the upload-ready banner export. | Proxy file reason, requested source export, target size, owner, and route to rerun after replacement. | Check replacement banner |
Banner file to platform upload acceptance record
Use this record after the launch decision is ready. It makes the final upload handoff explicit: one checked file, one publishing surface, one crop-safe preview, one platform-specific export decision, and one owner note before the banner goes live.
| Upload acceptance gate | Proof to carry forward | Accept when | Route |
|---|---|---|---|
| Final banner file identity | The file selected for upload is the same final export that passed the banner checker, not a screenshot, preview, or old campaign file. | Filename, dimensions, ratio, format, and owner match the checked banner result package. | Recheck final file |
| Publishing surface acceptance | The final upload destination is named before upload: YouTube channel art, LinkedIn profile banner, LinkedIn Page cover, Facebook cover, website hero, or OG card. | The selected file is not being reused across incompatible platform crops without a separate export. | Confirm surface |
| Crop-safe preview acceptance | Important text, logos, faces, products, and CTAs sit inside the platform-safe message area. | The platform preview does not hide the message behind profile overlays, mobile crop, device safe area, or card edges. | Review safe area |
| Platform-specific export acceptance | YouTube, LinkedIn, Facebook, website, Open Graph, and marketplace reuse each has a dedicated export when crop behavior differs. | The campaign owner can name which exported file belongs to each publishing surface. | Split exports |
| Uploader handoff line | The final note names the checked file, target match, crop-safe note, publishing surface, and owner before upload. | The uploader can publish the banner without guessing which file, crop, or platform route was approved. | Run handoff workflow |

Where this banner checker fits in ImageSizeKit
This page is the broad checker for wide header images. It sits between general file inspection and platform-specific crop guides: first confirm the exported dimensions here, then open the matching safe-area or social image guide before publishing.
| Discovery route | Why it links here | Open |
|---|---|---|
| YouTube Banner Safe Area | Use this route when a 2560 x 1440 channel banner also needs a safe-area check. | Open route |
| YouTube Thumbnail Size | Use the thumbnail page when a file is 16:9 but may actually be a wide banner or channel asset. | Open route |
| Social Media Image Sizes | Use the hub when the wide image may belong to LinkedIn, Facebook, Open Graph, ecommerce, or another social placement. | Open route |
| Image Size Checker | Use the generic checker first when you only know the exported file dimensions and not the final platform. | Open route |
Wide image checker routing bridge
Use this bridge when a wide exported image could be channel art, a profile header, a website banner, an Open Graph share card, or a reusable social cover. The goal is to start from the file evidence, then route the user to the narrowest platform guide.
| Bridge page | Entry role | How it routes into this checker | Open |
|---|---|---|---|
| YouTube Banner Safe Area | Channel-art safe-area entry | Use this crop page as the primary bridge into the broad banner checker when a 2560 x 1440 export may also be a LinkedIn, Facebook, or Open Graph-style wide image. | /youtube-banner-safe-area/ |
| YouTube Thumbnail Size | 16:9 image entry | Use this 16:9 page when a thumbnail-like export is actually too wide or too reusable to treat as a single YouTube thumbnail. | /youtube-thumbnail-size/ |
| Image Size Checker | Generic file evidence | Use the generic checker when the final platform is still unclear and the file facts should decide whether the image is a banner, thumbnail, or Open Graph card. | /image-size-checker/#checker |
| Social Media Image Checker | Cross-platform checker entry | Use the social checker when the wide export is part of a broader social, ecommerce, marketplace, or website preview workflow. | /social-media-image-checker/ |
| Social Media Image Sizes | Cross-platform hub entry | Use the cross-platform hub when the same wide creative may become a social header, cover photo, profile banner, marketplace cover, or website preview. | /social-media-image-sizes/ |
Banner Size Checker differentiation case
This section separates the broad wide-image checker from YouTube safe-area guidance, social image hubs, and Open Graph preview checks. Use it when the file is clearly wide but the final platform is still undecided.
| Differentiation point | Why this checker is distinct | Next action |
|---|---|---|
| Wide file evidence | This checker starts with the exported wide image and compares it against banner, cover, header, channel art, and profile-background targets before a user chooses a platform guide. | Keep YouTube banner pages and social image pages routing broad wide-image checks here. |
| Not the YouTube safe-area guide | The YouTube safe-area page explains one channel-art crop. This page checks whether a wide file belongs to YouTube, LinkedIn, Facebook, Open Graph, or another banner workflow. | Use /youtube-banner-safe-area/ for channel art crops, then route uncertain wide exports back to this checker. |
| Not a social image hub | The social hub groups many asset types. This checker narrows the decision to wide banners and headers after reading width, height, ratio, format, and file size. | Send 4:1, 6:1, 16:9, and wide cover files here before opening a final platform page. |
| Not an Open Graph preview | Open Graph preview images are share cards, not profile headers. This checker catches when a wide banner should become a 1200 x 630 website share image instead. | Route website share-card matches to /open-graph-preview-checker/ after the wide-image check. |
Broad banner query routing
Broad banner-size searches usually arrive before the user knows whether a wide image is a website banner, social header, YouTube channel art, or profile banner. This routing table keeps those searches tied to one concrete checker step and one follow-up guide.
| Broad query | How ImageSizeKit should route it | Next route |
|---|---|---|
| banner size checker | Use this page as the broad local checker for wide social headers, channel art, cover photos, and profile banners. | Run banner checker |
| website banner size checker | Check the raw dimensions first, then decide whether the image is a website hero, Open Graph preview, social header, or campaign card. | Route website banner |
| header image size checker | Treat this as a wide-image routing query until the final placement is clear: profile header, channel art, website hero, or reusable promo cover. | Route header image |
| profile banner size checker | Use LinkedIn, Facebook, or creator-channel guidance after the checker confirms whether the file matches a wide profile-header target. | Open LinkedIn guide |
| youtube banner checker | Compare the 2560 x 1440 export here, then check the 1546 x 423 center safe area before publishing channel art. | Check YouTube safe area |
Wide image routing
Queries such as header image size checker, profile banner size checker, channel banner size checker, and website banner size checker usually mean the user has one wide image but has not chosen the final placement. Check the file first, then route by crop behavior.
| Wide image case | What the checker result tells you | Next route |
|---|---|---|
| Social profile header | Very wide files often need LinkedIn, Facebook, or X/Twitter-style crop checks before profile upload. | Open LinkedIn banner guide |
| Channel art or creator header | A 16:9 or 2560 x 1440 file may be YouTube channel art, but the center safe area still decides whether text survives. | Check safe area |
| Website hero or marketing banner | A wide website image may not be a social header; check whether it will become a page hero, campaign card, or Open Graph preview. | Check OG preview |
| Reusable promo cover | If the same visual will be used across social posts, cover photos, and marketplace images, route it through the social checker first. | Open social checker |
Banner publishing surface decision matrix
After the checker reads a wide image, choose the publishing surface before resizing. Similar wide ratios can become YouTube channel art, LinkedIn headers, Facebook covers, Open Graph cards, marketplace covers, or thumbnail-style artwork with different crop rules.
| File evidence | Likely publishing surface | Decision before export | Route |
|---|---|---|---|
| 2560 x 1440 or 16:9 channel-art source | YouTube channel banner | Use the YouTube safe-area guide because the 1546 x 423 center band decides whether names, logos, and CTAs survive. | Check YouTube safe area |
| About 1584 x 396, 4:1, or profile-header crop | LinkedIn profile banner | Route to LinkedIn banner guidance and check the profile-photo overlay before reusing a generic wide banner. | Check LinkedIn banner |
| About 820 x 360 or Facebook cover-like crop | Facebook cover photo | Use the Facebook cover guide because mobile and desktop crops can hide edge text even when the file is accepted. | Check Facebook cover |
| About 1200 x 630 or 1.91:1 | Website share card | Route to Open Graph instead of a banner slot; the final test is metadata, crawler access, and preview cache. | Check OG image |
| 750 x 424, seller cover, or marketplace promo crop | Whatnot seller or show image | Use the marketplace guide when the wide file will become a seller cover, show thumbnail, or listing promo asset. | Check Whatnot image |
| 1280 x 720, thumbnail text, or video-poster creative | Thumbnail-style image | Use thumbnail guidance before forcing a 16:9 image into a banner workflow. | Check thumbnail route |
| Wide but no platform match | Unknown social or web banner | Read file facts first, then route by final placement instead of resizing blindly. | Check file facts first |
Check banner dimensions
Upload a final banner export and compare it to common social header and channel art targets.
Drop an exported image here or choose a file.
The check runs locally in your browser and compares the file to this page's target sizes.
Start with a YouTube channel banner: 2560 x 1440. Press Check sample to see the result path, then upload the final file for exact file-size evidence.
Canonical banner checker result action map
Use this map immediately after the banner checker returns a result. It turns the checked wide file into one publishing action, one route, and one proof record before the asset leaves ImageSizeKit.
| Checker result state | Publishing action | Proof to keep | Route |
|---|---|---|---|
| Target match is clear | Open the platform crop guide before upload because a matching canvas can still hide text, logos, faces, products, or CTAs. | Final file name, matched target, dimensions, ratio, file size, crop-safe note, and upload destination. | Review safe area |
| Close shape but too small | Re-export from the original source canvas at the chosen platform target, then run the banner checker again. | Current dimensions, target size, source file owner, and the reason the smaller export is not enough. | Calculate target size |
| One banner is used across platforms | Split the master artwork into platform-specific files before approval so YouTube, LinkedIn, Facebook, website, and marketplace crops do not fight each other. | Required export list, platform targets, reuse risk, and owner for each separate banner file. | Split platform exports |
| Wide file is a website share card | Move the asset into the Open Graph workflow instead of approving it as a profile header or channel banner. | Page URL, image URL, metadata owner, preview cache state, and whether the checked file matches og:image. | Validate OG preview |
| Screenshot, preview, or source file is unclear | Replace the proxy file with the original export before resizing because screenshots and downloaded previews can report the wrong banner dimensions. | Proxy-file reason, requested source export, target size, owner, and the route to rerun after replacement. | Check source export |
Banner checker repair route gate
After the checker reads a wide image, use this gate to decide whether the fix is a safe-area adjustment, platform-specific re-export, Open Graph workflow, thumbnail route, or basic file-dimension repair.
| Checker signal | Repair decision | Next route |
|---|---|---|
| Canvas matches, but text or logo crops | Keep the banner dimensions, move identity content into the platform safe area, and re-check the final export before upload. | Review safe area |
| One banner is planned for multiple platforms | Do not reuse a single wide export until each target has been checked. Export dedicated YouTube, LinkedIn, Facebook, or website versions when crop behavior changes. | Choose platform size |
| Wide file is actually a website share image | Move the file into the Open Graph workflow when it is meant for link previews, metadata cards, or social share debuggers rather than profile headers. | Check OG preview |
| 16:9 file looks like a thumbnail, not a header | Route 1280 x 720-style files to thumbnail guidance before forcing them into a channel banner or profile cover slot. | Open thumbnail guide |
| File is too small, compressed, or unknown | Use the generic image dimension checker and aspect ratio calculator before resizing from a screenshot, preview download, or wrong artboard. | Check file facts first |
Checker vs safe-area guide
A banner checker confirms the exported file. A safe-area guide tells you where the message should sit inside that file. Use both before publishing a channel banner, profile banner, Page banner, or cover photo.
| Step | Use when | Output |
|---|---|---|
| Check the exported file | You need to confirm that a final banner export is close to a YouTube, LinkedIn, or Facebook target. | Width, height, ratio, file size, and closest banner target. |
| Review the safe area | The canvas size is right, but text, logo, or CTA placement may crop on mobile or profile views. | Crop-risk guidance before upload. |
| Re-export separate banners | One wide creative is being reused across platforms with different crops and overlays. | Platform-specific banner files. |
Banner crop preview map
Size is only the first gate. Use the overlay after upload to compare the center-safe message area against common crop-prone placements.
| Placement | What the overlay means | Best next guide |
|---|---|---|
| YouTube safe area | Keep the channel name, logo, tagline, and CTA inside the center band. | Open guide |
| LinkedIn center band | Keep identity and offer text away from the profile-photo side and outer edges. | Open guide |
| Facebook mobile crop | Use the center of the cover image because mobile and desktop crops can differ. | Open guide |
What to do after the banner check
A successful dimension match is only the first signal. Use the result to choose the next guide, checker, or safe-area preview before uploading the same wide image to multiple platforms.
| Checker result | Next step | Open |
|---|---|---|
| Matches YouTube 2560 x 1440 | Open the safe-area guide before upload because the correct canvas can still crop text on mobile. | Check YouTube safe area |
| Matches LinkedIn profile or Page banner | Review LinkedIn-specific crop guidance before reusing the same artwork on a personal profile or company Page. | Open LinkedIn banner guide |
| Matches Facebook cover photo | Check mobile and desktop crop behavior before putting text or logos near the edge. | Open Facebook cover guide |
| Wide image but no close match | Route the file through the broader social image checker or social media image sizes hub before resizing blindly. | Open social image checker |
| Looks like a website preview image | Use the Open Graph preview checker instead of treating the image as a social header. | Open OG preview checker |
How to act on banner checker status
The checker reports a status for the nearest banner target. Use that status as a publishing decision, not as a final approval. Banners still need crop, safe-area, and platform-placement checks after the file dimensions pass.
| Checker status | What it means | Publishing decision |
|---|---|---|
| Fits target | The exported banner matches a configured target shape and is at least the target size. | Check safe area: Do not upload yet if the banner contains text or a logo. Open the platform guide and verify the safe area or crop behavior. |
| Close shape | The ratio is close, but the file is smaller than the target and may look soft after platform resizing. | Calculate target ratio: Re-export from a larger canvas at the target dimensions, then run the banner checker again. |
| Needs resize | The file does not match the expected banner shape for the nearest target. | Choose banner guide: Choose the final platform first, resize or crop toward that target, then check the corrected file before publishing. |
| Wrong asset type | Some wide images are actually Open Graph previews, website heroes, thumbnails, or reusable campaign graphics. | Route wide image: Route by publishing surface instead of forcing the file into a banner slot. |
Banner size failure diagnosis card
Banner checks fail in two different ways: the file can miss the target dimensions, or the file can match the target while the message still sits in a crop-prone area. Use this diagnosis card before deciding whether to resize, recrop, export separate platform banners, or route the file to an Open Graph/share-card workflow.
| Checker result | Likely cause | Fix before publishing | Next route |
|---|---|---|---|
| Correct width and height, but important text crops | The canvas matches a target, but logos, names, taglines, or calls to action sit outside the platform safe area. | Move identity content toward the center band and re-check with the platform-specific safe-area guide. | Open safe-area guide |
| Right wide shape, wrong platform target | A YouTube banner, LinkedIn banner, and Facebook cover can all look wide while using different target dimensions and crop behavior. | Choose the final platform first, then export a dedicated file instead of reusing one generic banner. | Choose platform guide |
| Banner is too small for the target | The image may have been downloaded from a preview, exported at a compressed size, or cropped from a smaller source. | Re-export from the original design canvas at the recommended target size. | Check file facts first |
| The checker suggests Open Graph instead | A 1200 x 630 website share image can be wide, but it is not a social header or profile banner. | Use the Open Graph checker and metadata guidance instead of placing the image in a banner slot. | Open OG checker |
| One banner works on desktop but breaks on mobile or profile pages | LinkedIn profile photos, Facebook mobile crops, and YouTube device crops can cover different parts of the same wide artwork. | Treat the exported file as a platform-specific banner and check the profile overlay or center safe area before reuse. | Check LinkedIn overlay |
Can I reuse one banner across platforms?
Reusing one wide image is tempting, but banner placements are not interchangeable. Use one master design file, then export platform-specific banners when the target size, ratio, or crop behavior changes.
| Source banner | Reuse risk | Why | Safest action |
|---|---|---|---|
| YouTube channel banner | High | The 2560 x 1440 canvas contains large outer areas that can crop differently from social profile headers. | Keep a YouTube-specific file and export separate LinkedIn or Facebook versions. |
| LinkedIn profile banner | Medium | The 4:1 shape is much wider than most website preview and Facebook cover targets. | Reuse only after checking the crop center and re-exporting the target canvas. |
| Facebook cover photo | Medium | Mobile and desktop crops can differ, so edge text may disappear even if the size is accepted. | Keep text centered and check the Facebook guide before publishing. |
| Open Graph image | High | A 1.91:1 share image is optimized for link previews, not profile headers or channel art safe areas. | Use it for metadata previews; export a separate banner when the placement is a header. |
Banner export split matrix
Use this matrix when a designer sends one wide master image for several placements. Keep the master artwork, but approve separate exports whenever platform crops, overlays, or link previews change the visible message.
| Master image use | Why one file fails | Separate exports to create | First check |
|---|---|---|---|
| Creator or brand launch banner | A YouTube channel banner needs a large 16:9 canvas with a narrow center-safe message area, while profile headers and cover photos use much flatter crops. | Export YouTube 2560 x 1440, LinkedIn profile 1584 x 396, Facebook cover 820 x 360, and Open Graph 1200 x 630 as separate files. | Start with YouTube safe area |
| Company profile header | LinkedIn profile and Page banners are both wide, but profile-photo overlays, Page cover placement, and website preview cards crop different regions. | Export LinkedIn profile 1584 x 396, LinkedIn Page 4200 x 700, website hero, and Open Graph 1200 x 630 separately. | Check LinkedIn banner |
| Campaign or webinar artwork | Event titles, dates, speaker faces, and calls to action often sit near edges that disappear in mobile cover crops or social share previews. | Export a social cover, a website hero, a thumbnail-style 16:9 image, and an Open Graph card from the same master design. | Check OG image |
| Marketplace seller or show cover | Marketplace covers, listing photos, and social banners can share a visual theme but usually need different safe areas for product, seller, or show text. | Export Whatnot 750 x 424, social banner, listing photo, and website preview variants instead of uploading one generic wide crop. | Check Whatnot image |
| Unknown wide image from a designer | A file that only looks wide may be a header, cover photo, channel banner, website hero, link-preview card, or thumbnail source. | Run the local checker first, identify the closest target, then export only the platform-specific files needed for the publishing plan. | Run banner checker |

Banner size checker FAQ
Which banner sizes can this checker compare?
It compares uploaded images against YouTube channel banner, LinkedIn profile banner, LinkedIn Page banner, and Facebook cover photo targets.
Does a matching banner size guarantee perfect cropping?
No. A correct banner canvas can still crop differently across devices. Use the platform-specific guide for safe-area and crop notes.
Should I check the file before or after export?
Check the final exported JPG, PNG, WebP, or AVIF file before uploading. Design canvases and downloaded previews can differ.
