The ideal height for cutting fabric is what is commonly referred to as ‘counter height’. Stand at your kitchen counter and you can get a very good ideal of the best height for a cutting table.
Working for even short periods of time on a cutting table that's too high or too low can make your back, shoulders, and arms tired and sore. As a general rule, a cutting table should be about waist-high to prevent stress on your upper body. Using that as a starting point, experiment with different heights to find the perfect table position for your body and the type of work you do.
Depending on how tall you are, the average height of a cutting table should be between 36 and 40 inches high, but you may want to lower it for workers.
