Your Facebook cover photo is the largest image on your profile or page — it's prime visual real estate that shapes a visitor's first impression within seconds. Because Facebook displays cover photos differently on desktop versus mobile, you need to crop strategically to ensure key elements remain visible on all screen sizes.
Facebook Cover Photo Dimensions
Facebook displays cover photos at 851×315 pixels on desktop and 640×360 pixels on mobile. The recommended upload size is 851×315px for profiles and 820×312px for pages. Facebook will centre-crop on mobile, so keep important content in the middle 640px wide area of your cover photo.
| Surface | Display Size |
|---|---|
| Desktop profile | 851 × 315 px |
| Mobile (safe zone) | 640 × 360 px (centred) |
| Facebook Page cover | 820 × 312 px |
| Group cover photo | 1640 × 856 px |

Tips for an Effective Facebook Cover Photo
Design for Both Desktop and Mobile
The edges of your cover photo (roughly 105px on each side) will be hidden on mobile devices. Design with a central "safe zone" in mind — put your logo, tagline, or key message within the central 640px to ensure it's always visible regardless of device.
Keep Text Minimal
Facebook's algorithm penalises ad images with too much text, but even for organic cover photos, a clean design with minimal text looks far more professional and loads faster on mobile. Let the visual do the talking, with a supporting word or short phrase if needed.
