If your Facebook cover photo looks blurry, stretched, or cropped in the wrong place, it’s almost always a size problem. Facebook resizes whatever you upload to fit its own dimensions, so getting the source file right the first time is the difference between a sharp, professional-looking Page and a fuzzy one.
Facebook Cover Photo Size (Quick Reference)
| Where it shows | Display size |
|---|---|
| Desktop | 820 × 312 px |
| Mobile | 640 × 360 px |
| Recommended upload | 851 × 315 px minimum |
| Sharpest result | 1640 × 720 px (2x size), PNG or JPG, kept under 100KB |
Why Your Cover Photo Looks Different on Mobile
Facebook doesn’t show the same crop of your cover photo on every device. On mobile, it trims roughly 90 pixels off each side compared to desktop. If your logo, text, or the main subject of your photo sits too close to the left or right edge, it can get cut off for anyone browsing on a phone — which is most of your audience.
To avoid this, keep anything important — text, faces, logos — inside a central 640 × 312 px safe zone. Backgrounds, gradients, and decorative elements can extend to the full canvas.
How to Upload a Cover Photo at the Right Size
Step 1: Design at 2x
Create your image at 1640 × 720 px. Designing larger than the display size and letting Facebook scale it down produces a noticeably sharper result than uploading at the exact display size.
Step 2: Keep the file size small
Facebook compresses large image files, which can introduce visible artifacts. Export as a PNG for graphics and text-heavy covers, or a compressed JPG for photos, and aim to stay under 100KB.
Step 3: Preview before you publish
After uploading, check how the cover looks on both desktop and your phone before you finalize it. Facebook’s editor lets you reposition the image if the crop doesn’t land where you want.
Facebook Profile Picture Size
While you’re updating your cover photo, it’s worth checking your profile picture too. Facebook recommends uploading a 400 × 400 px square image (or up to 720 × 720 px for extra sharpness on high-resolution screens). It displays at 176 × 176 px on desktop and 196 × 196 px on most phones, and it’s always cropped to a circle — so keep your logo or face centered rather than pushed to one corner.
Frequently Asked Questions
What is the exact Facebook cover photo size?
Facebook displays cover photos at 820 × 312 px on desktop and 640 × 360 px on mobile. Uploading at 1640 × 720 px gives the sharpest result across both.
Why is my Facebook cover photo blurry?
Usually because the source image was uploaded too small and Facebook had to stretch it. Uploading at 1640 × 720 px instead of the minimum size fixes most blurriness.
Can I use the same cover photo for a personal profile and a Page?
Yes — personal profile covers and Facebook Page covers use the same 820 × 312 px desktop dimensions, so one correctly sized image works for both.
Does my cover photo need to be a certain file size?
Facebook recommends keeping the file under 100KB. Larger files get compressed automatically, which can reduce quality more than compressing it yourself beforehand.
Getting your cover photo sized correctly is a five-minute fix, but it’s one of the first things visitors notice when they land on your Page. If you’d rather have your whole profile — cover photo, bio, and posting strategy — set up properly from the start, see our social media marketing service.
