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 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 |

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.
