The number of stitches (tufts) per running inch of carpet usually is specified directly for tufted carpet, but is called rows per inch for woven carpet. The numerical product of tuft rows per inch of width multiplied by stitches per running inch is the number of tufts per square inch, or tuft density.

Carpet Provides Warmth and Comfort In colder climates or seasons, carpet retains warm air longer than other flooring types. In addition to keeping your home cozy in the winter, this attribute conserves energy. Carpet also provides a comfortable place to sit, play, or work and gives a room an overall warmer feeling.
