The coarseness of sandpaper is measured in grits. The grit number on a piece of sandpaper relates to the number of holes per square inch in the screens used to sieve the grains during the manufacturing process.

The grit level is found ranging from a level of 12 to 600. For most of the home sanding operations the grit size can vary from 60 to 220 which is usually very commonly recommended by every technician.
