Pile height refers to the length of the carpet fibers above the backing and is typically expressed in fractions of an inch. The lower piles feel firmer and are more durable, and higher piles feel plusher but can be less resilient if not dense enough. Face weight quantifies how much fiber is present; the higher face weight often means a plusher look and softer feel. Density and twist also strongly influence the durability.
