A sandpaper’s rating is determined by its grit – which is the sharp particles glued to its surface – and the grit size – the number of particles per inch of sandpaper. The larger the grit size, the smoother the fine sandpaper and conversely, the smaller the grit size, the coarser the paper.
Sandpaper comes in a range of grit sizes for a host of different sanding jobs and is typically used to remove material such as paint or varnish or to smooth down and prepare a surface. They can also be used to make a surface rougher, for example when preparing for an adhesive.
A: Grit is the abrasive material that is glued to the surface of the sandpaper and provides a surface of varying coarseness that is used to polish, sand or strip a surface depending how hard and rough the grit is.
For a general sanding job, start off with a lower grit coarse sandpaper to remove those surface lumps and imperfections and apply enough pressure to keep the paper in place and moving smoothly. If you are sanding wood, sand in the direction of the grain and not against it and move back and forth in a straight motion.

A higher number indicates smaller particles, which don’t remove as much material but leave a finer, more polished appearance.
In addition to sandpaper, there are other abrasives, available in a range from coarse to fine:
