You might have noticed that Facebook changed the Group Cover Photo size on November 27, 2017.
We’ve spent a ridiculous amount of time in recent weeks figuring out the ideal dimensions for Facebook Group, Page and Cover cover photos. Googling it results in a mass of conflicting recommendations — mainly out-of-date.
Facebook finally announced the new size. Naturally, it crops differently on every device. (Why would Facebook make things easy?)
According to Facebook, the ideal size is 1,640px by 856px, or 1.91:1 ratio. For most devices.
HOW DOES FACEBOOK CROP COVER PHOTOS?
Below is our 1920px x 1080px cover photo. You’ll see the full image on mobile with top and bottom crops coming in for first tablets then desktop. The shaded area in the middle is what is visible on all devices so this is the safe area for text.
Different sizes for Facebook Groups, Pages and Profiles
If all these different sizes aren’t driving you crazy yet. We thought we’d share how they render for each device.
Facebook Group cover photo dimensions:
Overall — 820px x 461px
Mobile — 640px x 360px
Tablet — 820px x 303px
Desktop — 820px x 332px (1640px x 664px Retina Display)
For all the above create your image as 1920px x 1080px.
