KPSI stands for Knots per square inch and determines the number of knots in one square inch of the rug. It represents the overall number of knots used in creation of a handmade rug. Usually, City rugs have higher KPSI since they have more detail and they use finer wool. Tribal rugs have lower KPSI since their design is more simple and geometric.
