What matters
Steam Profile Photo dimensions at a glance
Steam profile photos display at 184×184 on profile pages and smaller in friend lists, comments, and game lobbies. Animated GIFs are supported for all users.
Your Steam avatar is your gaming identity across all Steam social features. It appears in every game lobby, friend list, and community interaction.
Low-res avatars look pixelated on profile pages. Non-square images get cropped, potentially losing important parts of the design.
