Facebook cover photo size

Meta’s guidance is written for Facebook Pages. A cover must be at least 400 pixels wide and 150 pixels tall, and it loads fastest as an sRGB JPG that is 851 pixels wide, 315 pixels tall and under 100 kilobytes. If the cover is mostly a logo or text, Meta suggests a PNG may give a better result. Its separate article on personal profile covers gives one size rule: the image has to be at least 720 pixels wide.

Third-party guides such as Sprout Social and Hootsuite give one Facebook cover size, 851 × 315, without separate figures for personal profiles and Pages. That makes 851 × 315 the starting point for either.

Look this up and you will find two sets of numbers. Meta’s help centre now describes the cover by its shape: 16:9 on computers and 2.4:1 on mobile. Many guides, including Hootsuite’s October 2026 update, still list fixed display sizes of 820 × 312 pixels on computers and 640 × 360 pixels on phones.

Both sets of figures agree on the part that matters. You upload one file at about 2.7:1, and the screens they describe show a squarer shape than that, so the sides get trimmed. At 16:9, a cover 315 pixels tall keeps only about 560 of its 851 pixels of width, roughly two-thirds. At 2.4:1 it keeps about 756, and at 820 × 312 almost all of it.

So follow the upload size every source agrees on, 851 × 315, and design for the crop rather than for one display size. After saving, look at the cover on a phone and on a computer, because each shows a different slice.

• Keep words, logos and faces in the middle of the image, well clear of both side edges.
• Leave the lower left free. The profile picture sits over that part of the cover, about 40 pixels deep on mobile according to Meta.
• Use large, simple lettering. On a phone the whole cover is a short band across the top of the profile, and small text becomes unreadable.
• Fill the edges with something that can be lost, such as a plain colour, a texture or sky.
• Don’t put a phone number or web address at the far right or left, where a crop can cut it in half.

Tip: When you set a new cover, Facebook lets you drag it to reposition it before saving. That rescues a photo, but a cover designed for the crop needs little or no adjusting.

1. Set the canvas to 851 × 315 pixels before you add anything.
2. Zoom your design down to phone size on screen to judge whether the lettering is still readable.
3. Save a photo as an sRGB JPG and aim for under 100 KB, the size Meta says loads fastest.
4. Save a cover that is mostly lettering or a logo as a PNG, which keeps edges crisp.
5. If the result looks soft on a high-resolution screen, try the same shape at double size, 1702 × 630, and compare the two.

Facebook group and event covers use different shapes from Page and profile covers, so reusing this file there leads to a different crop. Their own guides cover those sizes.
