What matters
Twitch Profile Photo dimensions at a glance
Twitch profile photos appear as circles throughout the platform — on channel pages, in directories, and in raid notifications. Animated GIFs are supported for Partner/Affiliate accounts.
Your avatar is your brand mark in every raid notification, directory listing, and chat mention. Recognizability at small sizes drives channel growth.
Non-square images get cropped into a circle awkwardly. Low-res avatars look unprofessional next to other streamers in directory listings.
