    What size is a profile picture?

    512×512 pixels, which is 1:1. 512×512 is comfortably above what any platform displays an avatar at, and square, which is what every one of them expects. One square file works for a forum, a Slack workspace, a GitHub account and a social profile rather than one per site.

    The thing that catches people out

    Most platforms mask an avatar into a circle. The corners of your square are decoration, not content: anything in them is cut off. Centre the face, leave room around it, and check what survives a circle before uploading.

    What a profile picture does to it afterwards

    512x512 is comfortably more than anywhere needs, which is the point: nearly every platform crops a profile picture to a circle and serves it at 40 to 200 pixels, so the file you upload is downscaled hard and you want detail to spare. The circle is the thing people forget. Anything in the corners of your square is cut off everywhere, so a logo that fills the frame edge to edge will lose its edges. Leave a margin and keep the subject centred and large.

    What the crop takes off

    A square, so a 4:3 photograph loses a quarter of its width from the sides - and then 512 pixels is small enough that most phone photographs are being reduced eightfold on top of that. Both are the right direction to travel. What it does mean is that a face already small in the frame becomes tiny: crop to the head before you resize, not after.

    Questions about a profile picture

    Why 512 pixels when it is displayed so small?

    Because you cannot know in advance which sizes it will be served at, and having detail to spare costs almost nothing at this resolution. Platforms show a profile picture anywhere from 40 pixels in a comment thread to 200 on a profile page, and each makes its own downscaled copies. Starting from 512 means every one of those is a reduction, which looks good, rather than an enlargement, which does not.

    What does the circle crop cut off?

    The corners, everywhere. Almost every platform now displays profile pictures as circles, which removes about 21% of a square image and all four corners with it. A logo that fills the frame edge to edge loses its edges, and text along the bottom disappears entirely. Leave a visible margin and keep the subject centred and large enough to read at 40 pixels, which is smaller than most people design for.

    Why 512 pixels rather than something larger?

    Because almost nothing displays a profile picture above about 400 pixels, and most places show it between 40 and 150. 512 gives every service room to make its own smaller copies without enlarging anything, and keeps the file small enough to upload to all of them quickly. What matters far more than the number is that the face fills the frame: a head that sits comfortably at 512 is unreadable at 40.
