In the world of luxury linen, thread count is an important measure for exclusivity. A thread count is the numbers of threads in one inch square of fabric-more the thread count, costlier the fabric. Thread count in sheets is the equivalent of dpi in photographs. It literally relates to number of threads in the wrap and weft of a square inch of fabric, and the quality of silk and linen is judged differently.
Generally, however, a higher number is considered superior, as it makes for a smoother and finer finish. It’s only one aspect of quality though”. The base fiber and the size and the quality of the yarns are far more important.
