Grit size refers to the size of the particles of abrading materials embedded in the sandpaper. These measurements are determined by the amount of the abrasive material that can fit through a square inch filter. [15] Several standards have been established for grit size. These standards establish not only the average grit size, but also the ...
ISO 6344 is an international standard covering the materials sizes and tests regarding sandpaper and other similar coated abrasives. It has three parts: ISO 6344-1:1998: Grain size distribution test; ISO 6344-2:1998: Determination of grain size distribution of macrogrits P12 to P220

Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
Grit size ranging from 2 mm (the large grain) (about F 10 using FEPA standards) to about 40 micrometres (about F 240 or P 360). These minerals are either crushed or are already of a sufficiently small size (anywhere from macroscopic grains as large as about 2 mm to microscopic grains about 0.001 mm in diameter) to permit their use as an abrasive.
