Choosing Image Dimensions for Profile Pictures

Updated June 23, 2026 · 9 min read

Dimensions decide how sharp an image looks and how heavy it is. Avatars are shown small and circular, so a modest square image is all you need.

Recommended settings for profile pictures

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 400 px on the long edge
Quality60
File size50 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Choosing Image Dimensions

Think about the largest size the image will ever be displayed at, then allow a little extra for high-density screens. For profile pictures, about 400 pixels on the long edge covers most cases.

Going much larger gives no visible benefit on screen but costs bandwidth and storage. Going smaller risks a soft look when people view it full screen.
