Raj in handwoven carpets

In the context of handwoven carpets, "رج" (pronounced "raj" in English transliteration) refers to the knot density or knot count. It is a unit of measurement used to express the number of knots per square inch (or per square centimeter) in a carpet.

For example, if a carpet is labeled as "55 رج" (55 Raj), it means that there are 55 knots per linear inch along both the warp and weft (vertical and horizontal) directions in a square inch of the carpet.

A higher number of Raj generally indicates a higher knot density, and it often correlates with finer and more intricate patterns in the carpet. However, the quality and overall appearance of a carpet depend on various factors beyond just knot count, including the quality of materials, craftsmanship, and design.
