Percale: For U.S. Standards Percale simply means that the material is a minimum of 180 threads per square inch, however, many European mills, as with Italian bedding, will refer to their 100% cotton bedding as Percale or Percalle which in this case means that the material is a 100% cotton and a type of construction which is consistent with percale in the U.S, meaning a non sateen 100% bed sheet.
8 Foot Round - 96"
Thread Count: Thread count is determined by how many threads are in one square inch of fabric.  In the 180 count sheets, one square inch of fabric would have 100 threads going in one direction, with 80 threads going in the opposite  direction.  Add the 100 with the 80 and that equals the 180 thread count.
