Facebook Image Sizes

Facebook uses different image sizes for feed posts, cover photos, profile pictures, and events. Each surface has its own crop behaviour — uploading at the exact spec keeps Facebook from auto-cropping in unhelpful ways.

Facebook image strategy

Facebook feed posts display at 1200×630 (1.91:1) when shared as link previews and 1200×1200 (1:1) when shared as standalone images. The 1.91:1 ratio matches Open Graph defaults, so external links auto-fill with the right size. Cover photos display at 851×315 on desktop but get cropped to 640×360 on mobile. Keep critical content (logo, key text) in the centre 640×360 area — anything in the side bars gets cropped on phones. Profile pictures are circular on desktop and square on most other surfaces. Upload at 320×320 minimum even though they display smaller — the platform uses the high-resolution source for retina screens and thumbnail generation. Event cover images use a wider 1920×1005 (1.91:1) crop and are the most prominent image on an event page. They scale down significantly on mobile, so keep text large and high-contrast. For ad creative, Facebook uses 1080×1080 (1:1) or 1080×1350 (4:5) for feed ads, and 1080×1920 (9:16) for Stories ads. Always export under 30MB — Facebook compresses anything larger.

Facebook sizing FAQ

What size is a Facebook cover photo?▼

Facebook cover photos display at 851×315 pixels on desktop and 640×360 on mobile. Upload at 851×315 with critical content in the centre 640×360 area so it survives the mobile crop.

What is the best size for a Facebook post image?▼

For standalone image posts, use 1200×1200 (1:1) or 1080×1350 (4:5) for the most feed real estate. For link share images, use 1200×630 (1.91:1) to match Open Graph defaults.

What size is a Facebook profile picture?▼

Facebook profile pictures display at 170×170 on desktop and 128×128 on mobile but should be uploaded at 320×320 or larger. They appear as circles, so centre the subject.

Why does my Facebook cover photo look stretched?▼

Cover photos that were uploaded at the wrong aspect ratio get stretched or letterboxed to fit 851×315. Resize your source image to exactly 851×315 before uploading.

What file format works best on Facebook?▼

JPEG for photos, PNG for logos and graphics with text or sharp edges. Facebook converts PNG to JPEG for some surfaces — if text quality matters, set the file to a transparent or solid colour background to keep the conversion clean.
