Facebook cover photo size in 2026: design at 851×315, it shows 820×312 on desktop and 640×360 on mobile. Keep key content centered and the file under 100KB.

A Facebook cover is one image shown at two different crops, which is why so many of them end up with a logo clipped on a phone or a tagline hidden behind the profile picture. The single number worth memorizing is the design canvas — 851×315 pixels — but the number that actually governs your layout is the center safe zone, because Facebook crops the top and bottom on desktop and the sides on mobile from the same upload.
This guide gives the current dimensions, where the safe zone sits, the file settings that keep it sharp, and the upload-and-preview flow that catches cropping before you publish. Note that Meta doesn't maintain one clean, fetchable help page with these exact numbers, and third-party guides disagree at the margins (851×315 vs 820×360 for the canvas, for instance), so the last step — previewing on both desktop and mobile — is not optional.
A cover photo is a one-time brand-chrome asset, and Kompozy doesn't manage your Page's chrome — you still upload the 851×315 file in Facebook yourself, and a dedicated design tool like Canva or Photoshop gives you more pixel-level control over that single banner than any generation engine should. Be honest about that boundary before the pitch. Where [Kompozy](/) actually earns its place is the far larger problem a cover photo only hints at: everything that fills the Page *under* that banner, kept visually consistent with it, on a cadence a cover you set once never demands.
Kompozy is a full AI content generation and multi-platform publishing engine, so once your cover establishes the look — the palette, the type, the logo lockup — a [Persona Brief](/glossary/persona-brief) captures that same voice and brand kit and governs every post from it. [HyperFrames](/glossary/hyperframes) then renders Infographic Photos, Quote Graphics, and brand-exact Carousel Posts that match the cover's design language pixel for pixel, so your Page doesn't have a polished banner sitting on top of off-brand feed posts. The center-safe-zone discipline this guide teaches for the cover is the same framing logic HyperFrames applies to every generated graphic, which is why the whole Page reads as one designed surface rather than one good header and a drift of mismatched uploads.
Then it ships them: [autopilot](/glossary/autopilot) schedules and publishes to Facebook — one of eight social platforms plus blog and email — through a per-post review gate, so the on-brand content that makes your cover look like part of a system keeps flowing without a manual export-and-upload pass per post. What stays yours is the cover itself and the judgment of what the brand should look like; Kompozy turns that established look into shipped, consistent volume. A solo creator keeping one Page on-brand fits Starter ($199/mo, 5,500 credits); a team running several branded Pages fits Pro ($499/mo, 18,000 credits); agencies managing client Pages use custom Enterprise.
Design at 851×315 pixels. Facebook displays it at 820×312 on desktop and 640×360 on mobile from that single upload, and the accepted minimum is 400×150. Because Facebook recompresses the file, starting at 851×315 keeps it sharp after that pass.
Yes — personal profiles and Business Pages use the same cover dimensions and the same desktop-vs-mobile crop behavior, so one 851×315 design works for both.
The center. Desktop trims the top and bottom (~75px each) and mobile crops the sides (~90px each), so only the central band — roughly 640×312 — is guaranteed to show on every device. Keep logos, text, and faces there, and leave the bottom-left corner clear for the profile picture.
Use sRGB JPG under ~100KB for photographic covers (fastest load), and PNG when the cover is mostly text or a logo, since PNG avoids the JPG artifacts that show on hard edges and small type.
