The number of threads per inch is a good indicator of the quality and comfort of a bed sheet set, but it shouldn’t be the only factor to consider.
For example, a sheet with 400 threads per inch can be a better product than a sheet with 800 threads per inch if the material, fiber processing and weaving are superior in quality. However, these last two characteristics are not listed on the label, so it is important to consult a sleep product specialist for advice.
The percale and satin labels
The percale label, which refers to a type of weaving, ensures a minimum of 180 threads per inch. Satin weaving is more glossy but offers a comparable softness.
