Skin
Skins refer to the textures that are placed onto the player character model. Skins can be created using a skin editor or the Character Creator, or they can be purchased in skin packs from the Marketplace. Players can change their skin in the Minecraft Launcher or Dressing Room.
The default skins are always available in the Minecraft Launcher or Dressing Room, including nine Minecraft characters. Skins can have different arm or height sizes; Ari, Kai, Steve, Sunny, and Zuri have wide arms by default, Alex, Efe, Makena, and Noor have slim arms by default.
Skins are divided into areas that act as the surface area of the character (e.g., front head area, left leg area, etc.) They are stored as 64×64 pixels templates, consisting of an inner and outer layer; each layer consisting 1,632 usable pixels, making 3,264 total. In Bedrock Edition, players can also use 128×128 pixels templates, consisting of two layers of 6,528 usable pixels, making 13,056 total.
