Instagram profile picture size

Upload 320 × 320. Instagram shows it at 110 pixels on your profile and 32 pixels beside every post in the feed — the 32-pixel version is the one that matters.

Thirty-two pixels is smaller than most people picture. At that size the only things that read are a single face, a single letter or a strong solid shape; a full logo with a wordmark becomes a grey smudge. If you run a brand account, the practical test is to shrink your avatar to 32 pixels and look at it next to a competitor’s — the one you can identify is the one that works. Instagram masks the square to a circle and re-compresses the upload, so use a simple high-contrast image rather than anything with fine detail.
