A yardage calculator converts the length, width and depth of a project into cubic yards, the unit used to order bulk materials like concrete, topsoil, gravel, sand and mulch. Enter your dimensions, and it calculates how much material to order so you don’t come up short or pay for extra.
The formula is: cubic yards = (length in feet Ă— width in feet Ă— depth in feet) Ă· 27, since one cubic yard equals 27 cubic feet. Depth is usually measured in inches, so divide by 12 first. For example, a garden bed 12 Ă— 8 feet filled 6 inches deep is 12 Ă— 8 Ă— 0.5 = 48 cubic feet, or about 1.78 cubic yards.
Different materials need different allowances. For concrete, add 5 to 10 percent extra for spillage and uneven subgrade. Gravel and soil compact after spreading, so order a bit more for areas that will be driven on or packed down. Bulk materials can also be priced by the ton, so ask your supplier for the conversion; gravel often weighs more than a ton per cubic yard.
Tips: measure each area separately and add them up, use the circle formula (Ï€ Ă— radius²) for round areas, and confirm whether the supplier has a minimum order or delivery fee. For small jobs, bagged materials may be easier.
