What matters
Facebook Group Cover dimensions at a glance
Facebook group covers have one of the more dramatic desktop-to-mobile crop differences. The desktop view is a wide banner; mobile shows a more square crop from the center.
Groups with clear, professional covers attract more join requests. The image sets expectations about the group's topic and tone.
Text or logos placed near the edges disappear on mobile. The group name and member count overlay the bottom, so content there gets obscured.
