Safe zone and tips
- Computers show a wide strip and phones a taller, narrower one, so the left and right edges are cut off on mobile. Keep text and faces in the centre.
- Facebook’s own advice: an sRGB JPG of 851 × 315 that is under 100 KB loads fastest.
- For logos and text, a PNG usually stays crisper than a JPG.
- Your profile picture overlaps the cover in some layouts; check the result on both a computer and a phone.
Making a 2.7:1 image from a phone photo
A typical 12-megapixel phone photo is 4032 × 3024. The largest 2.7:1 area you can cut from it is 4032 × 1492 pixels: crop to that, then scale it down to 851 × 315. Cropping first and scaling second keeps everything in proportion.
The calculator is set to 851 × 315. Enter your own width and height to see their ratio, or type a new width in box 2 to get the height that matches.
Frequently asked questions
What is the best size for Facebook cover photos?
Use 851 × 315 (Recommended upload, ≈ 2.7:1), 820 × 312 (Shown on computers, ≈ 2.63:1), and 640 × 360 (Shown on phones, 16:9). The first one is the safest default.
Which aspect ratio should Facebook cover photos use?
≈ 2.7:1, ≈ 2.63:1, and 16:9. Crop to the ratio first and then scale to the size in pixels, so nothing is stretched or cut off unexpectedly.
Why does my Facebook cover look cropped on my phone?
Phones show the cover at 640 × 360, which is much less wide than the 820 × 312 view on computers, so the sides are trimmed. Design at 851 × 315 but keep important content in the middle so it survives both crops.
