What is Thread Count?

A measurement of the thread density in bedding materials, thread count is measured by counting the number of threads in one square inch of fabric. Both length (warp) and width (weft) threads are counted in the measurement. For example, a sheet with 150 threads at the length and 150 at the width has a thread count of 300.

Thread count is important to shoppers because it can indicate fabric quality. High-thread-count fabric usually feels finer and smoother than fabrics with lower thread counts. Because of the increased thread density, high thread count extends the life of a bedding item. Common bed sheets have thread counts between 180 and 200. Fabrics with thread counts above 200 are considered to have high thread counts. Some manufacturers make luxury sheets with thread counts up to 800; however, thread counts stop feeling noticeably finer when counts exceed 400.
