This swelling capacity of it provides holding power and accuracy alignment. The thickness of the biscuits is 0.148 inches and available as three different sizes which are designated as #0, #10, and #20. Among them the measurement of the #0 is 5/8 inch wide and 1 3/4 inches long. On the other hand the #10, is 3/4 inch wide and 2 1/8 inch long whereas the #20, is 1 inch wide and 2 3/8 inches long.
