Sandpaper Grit Chart

Every numbered sandpaper and abrasive grit Supply Tie stocks, taken from our live abrasive listings: sheets, discs, belts, rolls, sponges, flap discs and flap wheels. Each row gives the grit, its grade, how many products we carry in that grit, and links that open the product with that grit already selected.

How to read a grit number

  • Lower number = coarser. The number is roughly how many openings per inch in the screen used to size the mineral. 24 grit removes material fast and leaves deep scratches, 400 grit and up leaves a smooth, fine finish.
  • Work up in steps. Don't skip more than about one grade at a time (for example 80, then 120, then 180). Each grit should remove the scratches from the one before.
  • P grades. Many sheets and discs are marked with a P (FEPA) number. Up to about P220 it is close to the same plain (CAMI) number, at finer grits the P number runs higher for the same scratch (P400 is close to CAMI 320, P800 to about 400, P1200 to about 600).
  • Named grades. Non-woven pads and some sponges are graded by name (Coarse, Medium, Fine, Very Fine, Ultra Fine, Super Fine) instead of a number. They are listed on each product.
