Thread Count

Thread count refers to the total number of threads woven into one square inch of fabric, calculated by adding the warp (lengthwise) threads to the weft (crosswise) threads. For example, a fabric with 200 warp threads and 200 weft threads per square inch has a thread count of 400.

While thread count is widely used as a quality indicator for bedding, the relationship between thread count and quality is more nuanced than marketing often suggests. The table below shows general quality associations, though these should be considered alongside fiber quality and weave type.

Higher thread counts don't automatically mean better fabric. The quality of the fiber itself matters far more than the raw count—a 400 TC sheet made from long-staple Egyptian cotton will outperform an 800 TC sheet made from inferior short-staple fibers. Additionally, some manufacturers inflate thread counts by using multi-ply yarns, counting each ply as a separate thread. This practice means that a claimed 1000+ TC fabric may actually have the same number of yarn bundles as a legitimately measured 400 TC fabric.

Weave type also affects how thread count translates to feel. A sateen weave produces a softer, more lustrous surface than a percale weave at the same thread count, because the longer float lengths in sateen allow more yarn surface to contact your skin. When evaluating bedding, consider thread count alongside GSM for a more complete picture of fabric weight and density.
