Facebook cover photo size in 2026: Meta has you design at 851×315px (sRGB JPG, under 100KB). Desktop shows it full-bleed at a 16:9 ratio, mobile at 2.4:1 — keep key content centered.

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 Meta's own Help Center defines the desktop and mobile views as two different aspect ratios (16:9 and 2.4:1) cropped from that same upload, not as one fixed layout.
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. A lot of older guides still cite flat pixel figures like 820×312 for desktop and 640×360 for mobile; Meta's current Help Center states aspect ratios instead, and those don't match those older numbers — which is exactly why the last step here, previewing on both desktop and mobile after you upload, 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, including Infographic Photos and Quote Graphics. [HyperFrames](/glossary/hyperframes) goes a layer further on Carousel Posts, rendering each slide as a brand-exact composition that matches the cover's design language pixel for pixel. So your Page doesn't end up with a polished banner sitting on top of off-brand feed posts — it 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 — Meta's Help Center says that size loads fastest as an sRGB JPG under 100KB. From that single upload, desktop shows the cover full-bleed at a 16:9 ratio and mobile at a 2.4:1 ratio, and the accepted minimum is 400×150.
Mostly. Meta's Help Center documents the 851×315 upload and the desktop/mobile crop specifically for Pages; personal-profile covers aren't covered by that same article, and some guides describe a different profile-picture overlap position for profiles versus Pages. Design at 851×315 either way, but preview your specific profile or Page before publishing.
The center. Desktop and mobile show your 851×315 upload at two different aspect ratios — 16:9 and 2.4:1 — and Meta doesn't publish the exact pixels either one trims, so only the center third of the image is reliably safe 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.
