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.

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.

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.
