Units of textile measurement

Textilefibers, threads, yarns and fabrics are measured in a multiplicity of units.

• A fiber is measured in terms of linear mass density, the weight of a given length of fiber. Various units are used to refer to the measurement of a fiber, such as: the denier and tex (linear mass density of fibers), super S (fineness of wool fiber), worsted count, woolen count, linen count (wet spun) (or Number English (Ne)), cotton count (or Number English (Ne)), Number metric (Nm) and yield (the reciprocal of denier and tex).
• A yarn or thread, a spun of fibers used for knitting, weaving or sewing, is measured in terms of count and yarn density.
• Fabric, material typically produced by weaving, knitting or knotting textile fibers, yarns or threads, is normally measured by weight, g/m , thread count (a measure of the coarseness or fineness of fabric), in ends per inch (e.p.i) and picks per inch (p.p.i).
