Facebook group cover photo size

Meta’s help centre gives the size in its article on adding or changing a group’s cover photo: “the recommended size for group cover photos is 1640 x 856 px (or 1.91:1 ratio).” That is a different article, and a different shape, from the Page cover one, which gives 851 × 315 with separate figures for computers and phones. The two big general guides don’t cover groups: neither Sprout Social’s nor Hootsuite’s image size guide, both updated in 2026, lists a group cover at all.

The figure is 1640 × 856, a 1.91:1 shape. The most detailed third-party guide we found, devoted to group covers and updated in April 2026, gives that size and says it comes from Facebook itself, which Meta’s article bears out. Most size sites repeat it, and at least one lists a 16:9 version, 1640 × 922.

Use 1640 × 856, the size in Meta’s article. If you already have a 16:9 design, it is 66 pixels taller, so keep its words well away from the top and bottom.

Meta’s article says only that group visitors may not see the entire image on a mobile device, and it marks the areas to keep important information out of in grey on a diagram. We could not read that diagram, so we can’t say which edges it shades. The third-party guide describes the reverse split: phones show a group cover in full, while computers trim the top and bottom and show roughly the middle 1640 × 662 pixels, which takes about 97 pixels from each end, a little over a ninth of the height each. Because the two accounts differ, treat the middle band as the only part every visitor is sure to see.

Unlike a Page, a group has no profile picture sitting on its cover, so the corners are free. The group’s name, its privacy setting and the member count appear below the image rather than on it.

Tip: Fill the top and bottom bands with something that can go without being missed, such as sky, a wall or a plain colour, and keep the subject in the middle band.

Because a group has no profile picture, its cover does that job too. A small square version appears beside the group’s name in places such as the list of groups in the sidebar and group posts in the feed, at a fraction of the size of the full cover.

At thumbnail size only shapes and colours survive. A cover with one bold element near its centre, such as a logo on a strong colour or a single face, still identifies the group; a wide photo of a crowd turns into an unreadable blur.

A Page cover is there to sell. A group cover has a different job: someone landing on it is deciding whether to join, so it should tell them who the group is for and what goes on inside.

• Customer community for a product: the product in use and the group’s name, so members know they are in the right place.
• Course or programme group: the course name and the cohort or year, which helps when one business runs several groups.
• Local group: a view people from the area will recognise at once.
• Buy-and-sell group: the area it covers and the kind of goods, in a few words.
• Hobby or support group: a warm, uncluttered image rather than a stock photo of people at laptops.

Leave the rules off the image. Groups have a rules section of their own, which is easier to read and to update than words inside a picture.

Meta’s help centre says only admins can upload or change a group’s cover photo. Go to the group, click Edit in the bottom right-hand corner of the cover, choose where to pick an image from (or choose Reposition), drag the image into position and click Save Changes.

Some Facebook images carry over and some don’t. An event cover made at the common 1920 × 1005 has the same 1.91:1 shape, so scaling it to 1,640 pixels wide gives 1640 × 858, and a two-pixel trim finishes the job. A Page cover at 851 × 315 is far longer and thinner: to fill a 1.91:1 frame it would lose more than a quarter of its width and need enlarging about 2.7 times, which leaves it soft.

1. Start a 1640 × 856 canvas rather than cropping a finished design to fit.
2. Mark the middle band, from about 97 to 759 pixels down, and keep every word and face inside it.
3. Save photos as JPG and designs with lettering as PNG, the format Meta suggests for Page covers that carry a logo or text.
4. Upload it from the group, position it, save, and then check it on a phone and on a computer.
