| Item | Desktop | Mobile | Text/logo placement |
|---|---|---|---|
| Upload size | Use 1640 × 856 px for a crisp wide group header. | Mobile can crop the header more tightly. | Keep group name, logo, and key image subject centered. |
| Display behavior | Wide group cover across the top of the group. | A tighter crop can hide edge details. | Leave edges as background or texture. |
Export checklist
Before you upload
Export the canvas at the target pixel dimensions before uploading.
sRGB is the safest color profile for Facebook and web display.
Compress photographic images so Facebook has less work to do.
PNG keeps hard-edged graphics and type cleaner.
Preview after upload because Facebook can crop or resize by surface.
Common mistakes
Avoid these image problems
Responsive crops can trim outer edges, especially on mobile.
Uploading below the target size can look soft after Facebook processing.
A mismatched canvas forces unwanted cropping or empty space.
Dense text becomes hard to read in feeds and on mobile screens.
Platform notes
Requirements and crop behavior
