Persian City carpets and rugs are made in and around the cities of Isfahan, Nain, Tabriz and Kashan. Almost all of the wool and silk city rugs have a high knot density, often between 5000’000 knots per square meter up to one million knots per square meter. Many of these rugs have a combination of wool and silk to enhance the detail of the rug.

The patterns are often inspired by the architecture of the area. They are also known for their high quality and intricate patterns. On the backside of the fringes there are marks called ‘kheft’ which is a way to measure the quantity of knots. The higher the number of knots between the marks the finer the rug. The warp is usually silk, sometimes cotton and the pile is a combination of wool and silk. The Isfahan motifs often consist of medallions, but figural motifs are also used.
An area where they have only been weaving carpets and rugs for just over 100 years, which is relatively new when it comes to the history of Persian rugs.
The rugs are described as 4La , 6La and 9La that is basically a way to recognise the the quality and number of knots. 9La can have up to 500,000 knots per square meter but a 4La, for example, can have up to 1.2 million knots per square meter. The more knots, the finer and more expensive the rug will be. Nain rugs have a cotton warp and a wool, or mixture of wool and silk pile. They are also recognisable with floral motifs in either an oall-over design or central medallion design.

The higher quality Tabriz rugs describe the quantity of knots per square meter by the word ‘Raj’. For example, 40 Raj refers to rugs with 400-500,000 knots per square meter, whereas a higher quality of 80 Raj has up to a million knots per square meter, though this is very rare to find these days. The warp is made of cotton or silk, and the pile is either wool or a combination of wool and silk. Some Tabriz rugs are recognisable with a cypress motif, or Mahi design, which means fish in Farsi.
