Multiply the square footage of the project area by 0.01235. The result is the amount of crushed rocks you’ll need in cubic yards. This will give you a 4-inch crushed rock base, which is the standard depth for a base when installing pavers.

How many bags of sand do I need for pavers? The recommended depth of sand for laying pavers is 1 inch. As one inch is 1/12 of a foot, divide the surface area, in square feet, by 12 to find the cubic feet of sand required. For example, a 60-square-foot patio requires 5 cubic feet of sand because 60/12 = 5.
