Reddit’s avatar builder lets you customize your appearance on Reddit with fresh gear, hairstyles, onesies, diamond hands, and other event-themed gear.
On the web, you can personalize your avatar from your profile page or profile card. Just click Create Avatar. On the iOS and Android app, tap your current avatar to open up your profile menu, then tap Create an avatar.
If you ever want to update your avatar, visit the same place and tap the Style Avatar button. Reddit adds new avatar gear all the time, so keep an eye out for new items. And keep in mind that some avatar gear is for Reddit Premium members only.
