What Is A Good Kpsi In Rugs

Again a rug with a lower kpsi value would take less time to make as compared to a rug with a higher kpsi.

What is a good kpsi in rugs.

Some rugs such as heriz tribal rugs and lower quality town city woven rugs fall under 100 knots and over 200 kpsi the rug starts to become fine. In general knot count ranges in rugs from about 25 to over 1 000 kpsi. To get a better perspective on the time taken to create a rug a persian rug measuring 9 by 12 and with a 500 kpsi ratio would take about 14 months to complete if worked on by 4 to 5 weavers working an approximate 6 hours a day 6 days. Low quality rugs hold a knot density of less than 80kpsi.

Kpsi is one of many ways rug experts may evaluate oriental rugs. Knot counts between 80 and 120 are mostly considered okay quality acceptable. Most rugs fall between 100 and 200 kpsi. What may be a coarse knot count for a city rug may be considered very fine by tribal rug standards.

The red circles show 2 nodes this is actually only one knot. A square inch measurement of a fine rug around 20 20 or 20 21 400kpsi. Note that the knotting in some rugs makes them look like they have twice as many knots horizontally than they actually have. The finest rug we ve seen at little persia was a silk chinese rug measuring around 2100 kpsi but most high quality silk rugs are 400 800 kpsi.

For best results kpsi should be measured in 3 or more areas to find an average as some rugs have kpsi which vary significantly. Designs of good quality rugs vs coarse weave carpets. Those pieces with 120 to 330 kpsi are rated medium to good while rugs with more than 330 kpsi considered to be of very good quality. Anything below 80 kpsi is considered to be coarse and of low quality.

Kpsi is also sometimes referred to as knot density and knot count which is somewhat of a quick simplification of what can be a complex equation of understanding quality. The density starts from 25 kpsi and could reach up to more than 1000 kpsi. That is to say not all countries regions and cities have the same standardized knot density measure of kpsi. The easiest but the most deceptive of the rug quality indicators is the concept of kpi or knots per square inch kpi is calculated by multiplying the horizontal knot count times the vertical knot count in a one inch area of the carpet.
