Sandpaper Grit Sequence Calculator
The free Sandpaper Grit Sequence Calculator answers one question: Which grits to use, in order. Enter your numbers in inches or millimeters and the result updates instantly in your browser, with no sign-up and no app to install. Use it on your phone at the bench, then copy or print the result for your cut list.
Never skip more than one grit step or the next paper can't remove the previous scratches.
