Which term describes the thickness of a roller cover?

Explanation:
The thickness of a roller cover is described by the nap—the height of the fiber pile from the roller’s core. The nap determines how much paint the roller can hold and the texture it leaves: a longer nap (thicker pile) holds more paint and creates more texture, which is good for rough surfaces; a shorter nap gives a smoother finish. While you might hear “pile” used in some contexts, the standard term for this dimension is nap, which is why it’s the best answer. Density refers to how many fibers are packed per area and doesn’t describe height, and length is not the specific term used for this property.
