Facebook Page photos: 320x320 profile, 16:9 and 2.4:1 cover

Facebook recommends a Page profile picture of 320 x 320 pixels, shown at 176 x 176 on computer and 196 x 196 on smartphones and cropped to a circle. The cover photo shows at 16:9 on computer and 2.4:1 on mobile, at least 400 x 150 pixels. So make one 16:9 cover with the important content in the centre band that survives both crops. Sume's Image API gives you the 16:9 frame directly.

The figures are from Facebook's help page, read on 2026-10-02.

What are Facebook's numbers?

The page splits profile and cover rules.

How do I design for two crops?

A 16:9 image is taller than a 2.4:1 one, so the mobile crop removes the top and bottom. Keep the logo, face or product in the middle third vertically and let the edges carry background only.

Request a 16:9 cover from Sume

Use aspect_ratio 16:9 and ask for open space at the top and bottom. For the profile picture use your real logo as a 1:1 PNG, because a logo should not be regenerated.
