500 x 500 pixels is a practical profile-picture square: the size commonly used for WhatsApp DPs and messaging-app avatars. It's large enough to stay sharp at every size a profile photo is actually displayed, while keeping the file small — and since most apps crop avatars to a circle, a centred square composition is what survives.

Profile photos rarely display larger than a couple of hundred pixels, so a 500 x 500 source is comfortably sharp everywhere — including retina screens that render at double density.WhatsApp DPs are the classic use: a 500 x 500 square uploads cleanly and stays crisp in chats, groups, and the contact view.
Most apps crop avatars into a circle. Everything in the corners of your square disappears, so centre the face and leave breathing room around it.A quick test: imagine the largest circle that fits inside the square — if the important content fits inside that circle, the avatar works.
At 500 x 500, files stay small enough to upload instantly on mobile connections while still downscaling cleanly to every avatar size an app renders.Start from a sharp source photo: enlarging a tiny image to 500 x 500 bakes in softness that no platform can undo.
