Texturing
Texel Density
Texture-to-surface ratio
Also known as: TD · Texels per cm · px/cm
Definition
Texel density is the number of texture pixels (texels) per unit of 3D surface area, usually measured in pixels per centimetre (px/cm). It defines how sharp or blurry a texture appears on a model relative to other objects in the scene. Consistent texel density across props is what makes a game scene feel cohesive — a wall at 10.24 px/cm next to a prop at 2.56 px/cm will read as a quality mismatch even with great art.
In production
Industry norms range from 5.12 px/cm for distant background props to 20.48 px/cm for hero assets. Tools like the Texel Density Checker Blender addon let you measure and equalise density across an entire modular kit before exporting to engine.
