Does a correct banner size guarantee a safe crop?
No. A file can match the target width and height but still crop important text or logos on mobile, profile, or preview surfaces.

How to check banner size and crop risk before upload
Wide banners are easy to export and easy to crop badly. Check the final file dimensions first, then verify platform crop behavior before uploading channel art, profile banners, cover photos, or website headers.
Final exportWide ratioSafe areaMobile crop
Quick answer
Start with the final exported file. A design canvas can look right while the downloaded banner is smaller, compressed, or the wrong ratio for the actual upload surface.
A correct banner size is only the first pass. If the image includes text, logos, faces, product screenshots, or calls to action, check safe-area and crop behavior before publishing.
Banner pre-upload workflow
- Export the final banner image file.
- Check width, height, aspect ratio, file size, and closest banner target.
- Confirm the final upload surface: YouTube, LinkedIn, Facebook, website header, or another wide placement.
- Check the safe area when the banner contains text, logo, face, product screenshot, or a call to action.
- Re-export platform-specific banner files instead of forcing one wide image into every crop.
Banners are not interchangeable

|---|---|---|
| YouTube channel banner | TV, desktop, tablet, and mobile crops can show different parts of the canvas. | Open guide |
| LinkedIn profile banner | The profile photo and mobile crop can cover important identity text. | Open guide |
| Facebook cover photo | Desktop and mobile crops can display different areas of the same image. | Open guide |
| Website hero banner | Responsive layouts can hide edge content even when the raw image is large enough. | Open guide |
| Open Graph image | A 1200 x 630 share card is wide, but it is not the same job as a profile or channel banner. | Open guide |
Banner checklist
- Check the exported file, not only the design canvas.
- Confirm whether the banner is wide enough for the target.
- Keep important text and logos near the center.
- Use a safe-area template when the platform crop is known.
- Preview the banner at small sizes before upload.
- Recheck on mobile and desktop after upload when the platform allows it.

FAQ
Should I use one banner for YouTube, LinkedIn, and Facebook?
Usually no. The assets are all wide, but they use different target sizes, overlays, and crop behavior. Re-export platform-specific files for important banners.
What should I check before uploading a banner?
Check the final file dimensions, aspect ratio, file size, target platform, safe area, text placement, and mobile or desktop crop behavior.
