Understanding Sandpaper Grit - The Spruce

Sandpaper grit is sized by a gauge nuer, with lower nuers signifying larger, coarser grits. So, for example, 24- or 40-grit sandpaper is a very coarse, rough sandpaper, while 1000-grit paper is extremely fine with very small abrasive particles. The grit nuer of sandpaper is almost always clearly printed on the back of the sandpaper itself.

The grit size of sandpaper is usually stated as a nuer that is inversely related to the particle size. A small nuer such as 20 or 40 indies a coarse grit, while a large nuer such as 1500 indies a fine grit.
