Length and density

The surface and the yarn in these fabrics are also called "pile". In particular "pile length" or "pile depth" refer to the length of the yarn strands (half-length of the loops). Pile length affects and is affected by knot density: "The greater the knot density, the thinner the weft and warp yarns and the more weakly are they twisted; the smaller the density, the coarser are the foundation yarns."Tzareva, Elena (1984).

', p.12-3. Penguin. . Designs and motifs are also affected by and affect pile depth: "A carpet design with a high knot density is better adapted to intricate and curvilinear designs, which of necessity must have a shorter pile length to avoid looking blurry. A carpet with a lesser knot density is better adapted to bold, geometric designs and can utilize a long pile for softer, more reflective surface that appeals to the sense of touch."Denny, Walter B. (2014). ''How to Read Islamic Carpets'', p.43 & 61. Metropolitan Museum of Art. .
