In Roblox, every player is automatically given an avatar, a human-like character which, by default, reflects the player’s appearance in all Roblox games.

Avatars may be customized with a vast array of body parts, accessories, clothing, skin colors, animations, and more. This gives players almost endless options to express their individual style, although you’re ultimately in control and may enforce a specific appearance for all avatars in your game.

Avatar Types

There are three types of Roblox avatars: R6, R15, and Rthro.

Construction

As the name suggests, R6 avatars are constructed of only 6 parts, giving them a very limited range of animated motion. R15 and Rthro expand the movement range by splitting the body into 15 parts.

Body Scaling

In addition to body parts, accessories, and skin colors, R15 and Rthro avatars allow for a customizable height, width, head size, body type, and proportions.

Basic Customization

If you prefer to define a more specific and less player-customized appearance for avatars in a game, you can customize them through Roblox Studio or runtime scripts.

Roblox Studio

In Studio, you can enforce the avatar type, body parts, body scaling, and clothing via the Avatar section of the Game Settings window (see /articles/game settings|Roblox Game Settings for more info). Note that if Body Type is set to 0%, avatars will have the proportions of a classic R15 avatar; if set to 100%, avatars will reflect Rthro proportions.

Runtime Scripts

In scripts, you can change avatar properties using the HumanoidDescription instance. See the /articles/humanoiddescription system|HumanoidDescription System article for details and practical code examples.
