The transparency must also be 0% or 100% as translucent colors are not allowed in either layer.

Transparency can be used, even on the first layer, though there needs to be at least one visible pixel, so a fully invisible skin can't be made. The normal templates still apply, but players get 4× the amount of pixels to work with, since both dimensions have been doubled. This means the skin template can be up to 128×128 instead of just 64×64. In Bedrock Edition, skins can have double the resolution of a normal skin. If a skin with transparent pixels on the first layer is uploaded, the transparent pixels render as black pixels in-game. In Java Edition, a skin allows only a solid color transparency is not allowed on the skin file except on the second layer, which is transparent by default playing offline, pixels can be left free resulting in 'holes' in the skin. The second layer can be used to give the character glasses, hats, or other accessories (even a bigger head).

Skins with slim arms have 3,136 pixels, with 1568 pixels on each layer. There are a total of 3,264 pixels that can be customized, with 1,632 on each layer. Skins are divided into areas that act as the surface area of the character (for example, the front head area, left leg area, etc.).
