Social media image sizes by platform and shape

What size does each platform ask for?

Type a platform or a size to narrow the list. Each row opens a page with the full rules and the resizer already set to that size.

Which sizes can share one export?

The same pixels can serve two slots only if the shapes agree. These groups are worked out from the sizes above, and the last column names the other slots an export of that row fits without being cropped.

Fitting is about shape, not resolution. A 400 by 400 profile photo is a square Instagram accepts, but it is small for a post. Export the square at 1080 by 1080 and it serves both, since LinkedIn only sets a minimum.

Where do other size charts disagree with the platforms?

These are figures the guides ranking for social media image sizes gave on September 25, 2026, next to what the platform's own help page says. The charts are not named, because the point is the number and a chart can be corrected.

Neither mistake breaks an upload. 1280 by 720 is the same 16:9 shape, so YouTube accepts it; it just asks for three times the width.

Instagram's range now runs to 3:4, so a 1080 by 1440 portrait posts without the crop a 4:5 chart would lead you to make.

Which platforms are missing, and why?

TikTok has a profile picture page and nothing else. We found no photo post size in its help centre, and the image specs TikTok does publish describe ad units, not posts.

Other platforms are added one at a time, each only after its own help page has been read.

These numbers move, so check the date

A passport size has been the same for decades.

A platform's recommended image size can change in a product update nobody announces, which is why every size here shows the date somebody read it at the platform's own help page rather than presenting it as timeless.

If that date looks old and the size matters to you, the link beside it goes straight to the page it came from.

That is one click to confirm, against the alternative of trusting a number copied between blog posts since 2019.

Why your photo gets cropped

Platform sizes are shapes as much as sizes, and a photograph is rarely already that shape.

The box is filled and the overflow comes off the long edges evenly, because the alternative is stretching the picture and a stretched face is the one result nobody wants.

If the centre is not the part you want to keep, open the crop tool, drag the frame to the right region, and come back. The crop stays applied while you set the size.

What happens to your photo?

Your selected photo is processed in your browser, without an image upload to a server. The page may download code and codecs needed for editing.

Save your result before closing the tab; unsaved edits are kept in memory rather than in an online account.
