Sandpaper Grit FAQ
The most common include 60-80 grit (coarse), 100-150 grit (medium), 180-220 grit (fine) and 320 grit (ultra-fine). There are also different types of sandpaper, such as ceramic alumina, silicon carbide and aluminium oxide.
Moreover, how do you know what grit sandpaper to use?
When shopping for sandpaper, you’ll see numbers such as 80-grit, 100-grit, or 200-grit. Keep in mind: The higher the number, the smaller the grains and the finer the sandpaper grit. And, conversely, lower numbers indicate larger grains and overall coarser sandpaper.
Simply so, what grit of sandpaper is extra fine? 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).
