Why Facebook Image Sizes Matter
Facebook displays images differently across desktop, mobile, and the Marketplace — and it crops aggressively when the ratio doesn't match. Uploading the wrong size means Facebook decides what to show.
Facebook Image Formats Explained
Facebook Feed Post (1200 × 630 px) is the standard format for link previews and standard posts.
Facebook Cover Photo (851 × 315 px desktop / 640 × 360 px mobile) is one of the trickiest sizes. Keep all important content in the center safe zone.
Facebook Story (1080 × 1920 px) uses the full screen.
Common mistakes to avoid
- Putting a logo in a corner of the cover photo — mobile crops it off.
- Uploading link previews at less than 1200 × 630 px — Facebook downscales them and blurs them.
- Confusing the desktop and mobile cover sizes.
