The 100 KB target
Facebook gives 100 KB as the size for the fastest loading cover, not as an upload limit. A JPG at 851 × 315 can usually reach it with moderate compression.
If your cover has a logo or text, Facebook's help page says a PNG may give a better result. A PNG is usually larger than 100 KB, so you trade a little loading speed for sharper edges.
Cover photo and profile picture together
The Page profile picture is 320 × 320 and is cropped to a circle. It displays at 176 × 176 on computers and 196 × 196 on smartphones.
Because the picture sits over the cover, design the two together and look at them side by side after uploading.
Tips
- Export the cover as an sRGB JPG, the colour profile Facebook's help page names.
- Leave the bottom 40 or so pixels free of text, since the profile picture overlaps that area on phones.
- Use PNG only when the cover is mostly text or a logo.
- Check the cover on a phone and on a computer before you announce a change.
Common mistakes
- Uploading a 16:9 photo, which is much taller than the 2.7:1 cover and loses a lot of its height.
- Putting a name or tagline along the bottom edge, where the profile picture covers it on phones.
- Going below 400 × 150, the minimum Facebook lists.
- Saving a detailed photo as PNG, which makes the file far larger than the 100 KB target.

Frequently asked questions
What size is a Facebook cover photo?
Facebook's help page gives 851 × 315 pixels for the fastest loading Page cover, saved as an sRGB JPG under 100 KB. The minimum is 400 × 150.
Is 100 KB a limit for Facebook covers?
No. Facebook describes it as the size for the fastest loading cover, which is advice for speed rather than an upload limit.
How much does the profile picture cover?
Facebook says the profile picture overlaps the cover photo by about 40 pixels on mobile devices.
Should my cover be JPG or PNG?
JPG loads fastest. Facebook suggests PNG for covers with a logo or text, where it keeps edges sharper.
Why does my cover look different on my phone?
Facebook shows the cover in a different shape on phones and computers, so the edges are trimmed in one view or the other. Anything people need to see belongs near the centre.
