Sandpaper Belts are measured by the “Width of the belt” x “Length of belt” x “Grit”. Sandpaper Rolls are measured by the width x length x grit. Sandpaper Flap Wheels are measured by the diameter x width x shaft diameter x grit.
There are a couple of different ways to determine the correct belt size to fit your machine. The pictures shown are for a 1″ x 30″ long belt. If you have an old, worn out belt, simply cut the belt apart.
Option#1 Lay the belt flat on a table and measure the width and the length, the length will be doubled to give you the belts actual length. Option #2 Roll Length, mark the inside of your belt with a marker and lay the belt on the floor marking on the floor where the mark is on the belt. Roll the belt along the floor until you come to the mark on the back of the belt again and mark the floor again.
If you have an old worn out belt that you’re going to throw out, cut it in half, lay it out on a flat surface and measure the length to get the total belt length. Double the length you just measured and you’ll have the total belt length. Measuring to ensure you have the correct belt length is a simple but VERY important process.
