Facebook Cover Photo Size
A Facebook cover photo is 851 × 315 px on desktop and 640 × 360 px on mobile. These are different aspect ratios, not just different sizes, so Facebook crops the same upload two ways: desktop trims the top and bottom, mobile trims the left and right. The region that survives both is roughly the central 640 × 315 px — anything outside it is visible to some visitors and invisible to others.

Design Tips
- →Upload at 851 × 315 px and keep every logo, headline, and face inside the central 640 × 315 px. That is the intersection of the desktop and mobile crops and the only area guaranteed to be seen by everyone.
- →On personal profiles the profile picture overlaps the lower-left corner of the cover. Leave roughly the left 180 px of the bottom half clear, or your artwork sits behind the avatar.
- →Facebook compresses cover photos aggressively. Keeping the file under 100 KB triggers a lighter compression path and preserves noticeably more detail than a 2 MB upload of the same image.
- →Use PNG when the cover contains text or a logo, JPG when it is photographic. Text rendered through Facebook's JPG recompression develops visible fringing at this width.

What size is a Facebook cover photo?+
851 × 315 pixels on desktop and 640 × 360 pixels on mobile. Upload a single 851 × 315 px image — Facebook derives both crops from it. Keep important content within the central 640 × 315 px so it survives on both.
What are Facebook cover photo dimensions in 2026?+
The upload size remains 851 × 315 px (2.7:1). Facebook renders it at 820 × 312 px on desktop browsers and 640 × 360 px on the mobile app. A minimum of 400 × 150 px is enforced, but anything below 851 px wide is upscaled and appears soft.
Why is my Facebook cover photo cropped on mobile?+
Because the mobile crop is 640 × 360 px — taller and narrower than the 851 × 315 px desktop crop. Facebook trims the left and right edges to fit. Move any content sitting near the horizontal edges into the central 640 px band.
What size is a Facebook page cover photo?+
The same 851 × 315 px as a personal profile, but Pages do not have the profile-picture overlap on desktop in the same position, so more of the lower-left corner is usable. Group covers are different again at 1640 × 922 px.
Can I use a video as a Facebook cover?+
Pages can use a cover video at 1250 × 463 px, between 20 and 90 seconds. Personal profiles cannot. The cover video is a different size from the 851 × 315 px static cover photo, so it needs to be composed separately rather than exported from the same file.
