Profile picture sizes, and the circle that eats them
Every platform in this list stores a square and shows a circle. That one fact explains most of what goes wrong with profile photos: the corners of your picture are never displayed, the display size is usually far smaller than the stored size, and a photograph framed for anything else loses exactly the parts that made it work.
Short answer
Square, centred on the face, at least the platform's stored size: LinkedIn and X 400 x 400, Instagram and Facebook 320 x 320, YouTube 800 x 800, Discord 512 x 512. Going larger than the minimum costs nothing and survives re-encoding better.
The sizes
Only YouTube's own help material names a figure. The rest are what independent references consistently report, because these platforms do not maintain specification pages the way a passport office does - and all of them re-encode what you upload. Treat these as the sizes that work rather than as rules somebody published.
- LinkedIn - 400 x 400
- X - 400 x 400
- Instagram - 320 x 320 stored, displayed much smaller
- Facebook - 320 x 320 stored, with several display sizes
- YouTube - 800 x 800 recommended
- Discord - 512 x 512, which covers every size it renders
Why the circle matters more than the number
A square masked to a circle loses about 21% of its area, all of it at the corners. A centred head and shoulders survives that without anybody noticing. A photograph where you are off to one side, or standing at a distance, does not.
Scale is the second consequence. A LinkedIn photo is large on your profile and tiny in a feed; an Instagram avatar is small almost everywhere. The test that matters is not whether the picture looks good full-size, but whether your face is recognisable when it is the size of a fingernail.
The method
The work is in the crop. Getting the square right is most of the job, and the resize is arithmetic after that.
- Start from the sharpest original you have - not a screenshot, not something already posted and re-compressed.
- Crop square with your face in the middle third, closer than feels natural.
- Resize to the platform's size, or twice it if you want it to hold up on a high-density screen.
- Check it small. Shrink it to a thumbnail and see whether you can still tell who it is.
Common mistakes
Uploading something smaller than the stored size. The platform enlarges it and it looks soft. Going larger costs nothing.
A full-body photograph. Unrecognisable at feed size, which is where most people will see it.
Detail near the corners. The circular mask removes it.
Re-using something already compressed. Every re-encode compounds; start from an original.
Frequently asked questions
- Why does my profile picture look blurry after uploading?
- Two usual causes. Either it was smaller than the size the platform stores and got enlarged, or it had already been compressed - a screenshot of another post, say - and the platform's own re-encoding compounded that. Starting from a large, sharp original fixes both.
- Should I upload bigger than the recommended size?
- Yes, within reason - twice the figure is a sound rule. High-density screens draw roughly two physical pixels for every CSS pixel, and every platform re-encodes what it receives, so the extra data absorbs that loss instead of your face doing it.
- Can a profile picture carry location data?
- It can, if it came off a phone with location services switched on. These pages strip metadata from what you download, which is worth having for a file you are about to hand to a platform and publish under your name.
