You can easily calculate the knot density yourself by counting the number of knots 1 cm down and 1 cm across, and then multiplying these numbers together. Then multiply the total by 10,000 to give the number of knots per m².

Some carpet sellers exaggerate the knot density, so to be sure that you are comparing like for like when it comes to price, it is worth checking the knot density yourself. Most of CarpetVista’s carpets have a photograph of the reverse with a ruler, making it easy to examine the knot quality and count the exact knot density before choosing your carpet.
