Cubic Yard Calculator
Cubic yards = length (ft) x width (ft) x depth (ft) divided by 27. A 10 x 10 ft area at 3 inches deep is 0.93 cubic yards.
A cubic yard is 27 cubic feet — a cube three feet on each side. Enter your area and depth below and this calculator does the division for you, then converts the result into cubic feet, common bag sizes and an approximate weight.

Cubic Yards questions people actually ask
- How many cubic feet are in a cubic yard?
- Exactly 27. A cubic yard measures 3 ft x 3 ft x 3 ft, and 3 x 3 x 3 = 27 cubic feet.
- How do I convert square feet to cubic yards?
- Multiply the square footage by the depth in feet, then divide by 27. For inches, divide the depth by 12 first — 100 sq ft at 3 inches is 100 x 0.25 / 27 = 0.93 cubic yards.
- How much does a cubic yard weigh?
- It depends on the material: mulch is around 800 lb, topsoil about 2,200 lb, gravel roughly 2,800 lb and wet sand near 3,000 lb per cubic yard.
- How much area does a cubic yard cover?
- 162 sq ft at 2 inches, 108 sq ft at 3 inches, 81 sq ft at 4 inches and 54 sq ft at 6 inches deep.

- Topsoil CalculatorOne cubic yard of screened topsoil covers about 108 square feet at 3 inches deep and weighs roughly 1.1 tons.
- Gravel CalculatorOne cubic yard of gravel weighs about 1.4 tons and covers roughly 81 square feet at 4 inches deep — the standard depth for a driveway layer.
- Mulch CalculatorA cubic yard of mulch covers about 108 square feet at 3 inches deep, so most beds need roughly 1 cubic yard (13.5 two-cubic-foot bags) per 100 square feet.
- Dirt CalculatorYards of dirt = length x width x depth in feet divided by 27. A 20 x 20 ft area filled 6 inches deep needs 7.4 cubic yards, or about 10 tons.
How this number is calculated
Conversions are exact geometry (27 cubic feet per cubic yard). The 2,000 lb/yd³ default weight is a mid-range figure for mixed landscape material. Volume is area × depth, converted to cubic yards by dividing cubic feet by 27. See all our assumptions.
