How the paver count is calculated
Each paver covers its width times length in inches, divided by 144 to get square feet. Divide the area, with a waste allowance, by that for the count:
Under the pavers you need a base. Allow about 4 inches of compacted gravel and 1 inch of bedding sand, which the calculator gives in cubic yards. Add 5 percent waste for a simple running bond, or 10 percent for herringbone, circles, and curved edges.
