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.
There are two types of Roblox avatars: R6 and R15.
As the name suggests, R6 avatars are constructed of only 6 parts, giving them a very limited range of animated motion. R15 expands the movement range by splitting the body into 15 parts.
In addition to body parts, accessories, and skin colors, R15 avatars allow for a customizable body type, height, width, head size, and proportions.
|Body Type||Value from 0% (blocky, toy-like characters) to 100% (tall, human-like characters). A body type of 100% is sometimes called Rthro. Bundles tagged in the Catalog will set the body type to 100% when equipped, but they can still be used with any body type and any other avatar parts.|
|Height / Width||The relative height and width of the avatar. Height is constrained to values between 90-105% while width is constrained to values between 70-100%.|
|Head||The relative scale of the avatar's head to its body, constrained between values of 95-100%.|
|Proportions||When set to 0%, the overall body proportions are wider and taller with broad shoulders. When set to 100%, the body proportions are narrower and shorter with slender shoulders.|
If necessary, a player’s avatar type can be detected through the
Humanoid/RigType property, for instance within a
LocalScript as follows:
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.
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.
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.
