What is the sandpaper grit scale?
The grit of sandpapers is a rating of the size of abrasive materials on the sandpaper. The higher grit number is equivalent to a finer abrasive, which creates smoother surface finishes. Lower grit numbers represent coarser abrasives that scrape off materials much quicker.

On most raw woods, start sanding in the direction of the grain using a #120-150 grit paper before staining and work up to #220 grit paper. Soft woods such as pine and alder: start with #120 and finish with no finer than #220 (for water base stains) and 180 grit for oil base stains.
Is sandpaper rough or smooth?
Sandpaper materials are rated for coarseness or fineness by their grit number. The higher the number, the finer the grit, and the less rough the sandpaper. Coarse sandpaper removes material faster but leaves deep scratches. Fine sandpaper removes less material and leaves a smoother surface.
