Facebook Cover Photo Size (2026) — And the Mobile Safe Zone

Published August 24, 2026

You upload a cover photo, it looks perfect on your laptop, and then you open Facebook on your phone and the left third of your logo is gone. This is the single most common Facebook design complaint, and it isn't a bug. Desktop and mobile show different crops of the same file. Once you know the shape of each crop and the strip where they overlap, the problem disappears for good.

The numbers, in one table

These are the display dimensions Facebook currently uses for personal profiles and Pages. The cover is the big banner across the top; the other sizes are the ones people usually ask about in the same breath.

Facebook does adjust these from time to time, so treat the pixel counts as the current target and the shape as the durable part. A cover that is correctly proportioned survives a layout tweak; one that was hand-cropped to fit last year's pixel grid usually doesn't.

Why mobile cuts your cover — and by how much

Here is the part almost nobody explains properly. Facebook doesn't shrink your cover for phones; it takes a taller, narrower slice out of the middle and throws away the sides.

Line the two crops up. Desktop is 820 wide by 312 tall. Mobile is 640 wide by 360 tall. Mobile is 48 pixels taller but 180 pixels narrower. Since the crop is centred, that means roughly 90 pixels vanish from the left edge and 90 from the right when someone views your profile on a phone.

Ninety pixels out of 820 doesn't sound like much until you realise it's where people habitually put things: a logo in the top-left, a website address in the bottom-right, the edge of a product shot. Those are exactly the elements that disappear for the majority of your audience, because most Facebook viewing happens on a phone.

The safe zone: the middle 640 pixels

The safe zone is the overlap — the band that both crops include. On an 820-pixel-wide cover it is the central 640 pixels, leaving a 90-pixel margin on each side that only desktop users see.

The working rule is simple: design edge to edge, but put everything that matters in the middle. Your background photo, gradient or texture can run the full width, because losing its edges costs you nothing. Your logo, tagline, phone number, call to action and any faces should sit comfortably inside the central band, with a little breathing room so nothing kisses the crop line.

There's a second bite to plan for. On desktop, your circular profile photo overlaps the bottom-left corner of the cover, and on mobile it sits centred over the bottom edge. Either way, keep the lower strip of your cover visually quiet — no text in the bottom-left on desktop layouts, and nothing you'd hate to have a circle sitting on. A calm gradient or an out-of-focus area down there looks deliberate on every device.

How to resize your cover photo, step by step

You don't need Photoshop or a design subscription for this. The Toolyard Social Media Resizer has the Facebook Cover size built in and runs entirely inside your browser, so your image is never uploaded anywhere.

1. Open the Social Media Resizer and drag your image onto the drop area, or click to browse. JPG, PNG and WebP all work, and you can drop several at once if you're testing options.
2. In Target size, choose Facebook Cover (820×312). The preview updates immediately.
3. Pick your Fit mode. Cover fills the whole banner and trims the overflow — right for photos, where losing a little sky or floor doesn't matter. Contain shrinks the entire image to fit and pads the rest with a background colour you choose — right for a logo or graphic you cannot afford to crop.
4. Set the Format. JPG for photographs; PNG if your cover is a flat graphic with text, where JPG compression tends to fuzz the letter edges.
5. Click Download, then upload the result to Facebook.
6. Check it on your phone before you call it done. Thirty seconds now beats discovering next week that your web address is invisible to most of your visitors.

Why covers come out blurry (and how to avoid it)

Blurry covers almost always come from one of two mistakes, and they pull in opposite directions.

Uploading something too small. If your file is 500 pixels wide, Facebook has to stretch it to fill an 820-pixel slot. Enlarging invents pixels that were never captured, and the result is soft and slightly mushy. You cannot fix this after the fact — always start from an original that is at least as wide as the target.

Uploading something enormous. Hand Facebook a 6000-pixel-wide photo straight from a camera and it will compress it hard on the way down, which is where you get blocky skies and haloed text. Resizing to the cover shape yourself, before uploading, leaves far less for Facebook's compressor to do — and less compression means more of your original detail survives.

If you want a little extra sharpness on high-density screens, upload at exactly double the target: 1640 × 624. It's the same 2.63:1 shape, so it drops into the same slot, but retina displays get more real pixels to work with. Keep the file under a couple of megabytes and you get the benefit without a slow upload.

Is it private and free?

Yes to both. The Toolyard resizer is completely free — no account, no watermark, no limit on how many images you run through it. And it is 100% private, because the resizing is done by JavaScript on your own device. Your photo is never uploaded to a server, which matters more than people assume: cover photos are often family pictures, staff shots or unreleased product images. Once the page has loaded, it even works with your connection off.
