You can measure a brand new belt by easily first measuring the width, then laying the belt down as flat as possible without bending or creasing the belt in a way that will damage it, measuring from one end to the other, then DOUBLING the size as this is a belt and NOT a flat sheet in this instance. The second way would be to take your belt and easily measure the width of the belt. This measurement will give you your belt LENGTH. This is the best method for measuring your sanding belt if it is an old, used belt that you don’t care to use anymore.
If you don’t know the correct belt dimensions for your belt sander, there are four quick and easy methods you can use to determine the correct belt size.

How do I choose a sanding belt?
Choosing the Right Sanding Belt Grit The heavier the job, the coarser the sanding belt you’ll need. 40 to 60 grit is best suited for the heaviest work. When you’re performing tasks such as smoothing surfaces or removing minor blemishes, you’re better off using sandpaper with 80 to 120 grit.
How tight should a sanding belt be?
Most wood sanding applications require a belt tension near 40 psi. Because the goal is to keep the belt from slipping, users sometimes err on the side of using too much belt tension. Several problems can result from excessive belt tension.
How is sandpaper measured?
In addition, sandpaper is measured by its grit size, or number of sharp particles per square inch of sandpaper. The larger the grit size, the more edges there are and the smoother the sandpaper. The density of the grit is important, too.
How much sandpaper do I need?
For you to ensure that there are no stains left on the floor you will need an extremely coarse sandpaper for you to get down to the original floor. To get a really nice smooth finish, you have to sand the floor with a 60-grit paper, 100 and a 120-grit paper.
What is the common size for abrasive sandpaper?
Sandpaper is sized in grits, the most common grits ranging from 40 – 400 grit. The lower numbers paradoxically signify the larger, coarser grits, and the larger numbers indicate a finer, less abrasive sandpaper.
Which is coarser 150 grit or 60 grit?
Coarse grits are typically in the 40- to 50-grit range. Medium sandpaper, ranging from 60- to 100-grit, accommodates some final shaping.

Are V belts measured inside or outside?
Inside Belt Lengths: The inside length is measured with flat pulleys or a tape measure. As with the outside length, the inside length varies with the manufacturer. This length should not be used. 3.
How do you calculate pulley ratios?
There are complicated formulas for determining pulley ratios but in generic, layman terms, simply divide the driven component (pump) by RPM, the driver component (motor or engine) rated by RPM to get the required ratio. In the example below, the pump RPM is 1070, for full output, while the motor is 1750 RPM.
