You can purchase single 1/4 sheet sandpaper or a sheet and cut it in 4 for a total of 4 pieces .The lower the number, the more coarse the grit. Sandpapers are commonly graded as coarse (40 to 60 grit), Medium (80 to 120), Fine (150 to 180), Very Fine (220 to 240), Extra Fine (280 to 320) and Super Fine (360 and above)
