The official Facebook page cover photo size is 851 × 315 pixels (aspect ratio ~2.7:1), displaying at 820 × 312 pixels on desktop computers and 640 × 360 pixels on mobile smartphones. Because mobile crops the sides while desktop crops top and bottom, design within a centralized safe zone of 640 × 312 pixels. Feed posts are best sized at 1200 × 630 pixels (1.91:1).

Solving the Facebook Cover Mobile vs Desktop Crop Problem
Facebook applies different aspect ratios depending on device type: on desktop monitors it displays your cover at 820 × 312 px, but on smartphones it displays at 640 × 360 px (taller aspect ratio). An image formatted to 851 × 315 px will have roughly 105 px cropped from the left and right sides on mobile. Placing text, logos, and phone numbers in the central 640 × 312 px area prevents content cutoff across all screens.
Preventing Compression Artifacts on Facebook
Facebook heavily recompresses uploaded cover images to save bandwidth. To avoid muddy JPEG artifacts, upload in sRGB color space and keep file sizes under 100 KB whenever possible. You can use our companion /tools/image-compressor to compress your banner to an exact KB limit before uploading.
Frequently asked questions
What is the official Facebook cover photo size in 2026?
Facebook's official specification is 851 pixels wide by 315 pixels tall. It must be at least 400 pixels wide and 150 pixels tall to be accepted by Meta.
Why does my Facebook cover photo get cut off on mobile phones?
Desktop displays the cover at an ultra-wide ~2.7:1 ratio, while the mobile app crops the sides to render a taller view. Centering your important design elements inside the 640 × 312 px safe area prevents mobile clipping.
What is the ideal size for a Facebook timeline post image?
For single-image feed posts and shared link previews, 1200 × 630 pixels (1.91:1 aspect ratio) provides maximum visual fidelity across both mobile apps and desktop web.
How do I prevent Facebook from compressing my photos to low quality?
Pre-resize your image to exact pixel dimensions (851×315 for covers, 1200×630 for posts) and save as high-quality JPEG or PNG. Bypassing Meta's server-side downscaler prevents image degradation.
