Cubic Yard Calculator

Cubic yards from feet and inches for any area: rectangles, circles and triangles added together, with cubic feet and m³ and an optional weight.

A cubic yard is a cube 3 feet on each side: 27 cubic feet, or 0.765 cubic metres. Concrete, gravel, topsoil and mulch are all sold by the yard in the US. To get cubic yards, multiply length × width in feet by the depth in feet and divide by 27, or use the shortcut length (ft) × width (ft) × depth (in) ÷ 324. A 12 × 10 ft area 4 inches deep is 12 × 10 × 4 ÷ 324 = 1.48 cubic yards. Enter one area or several, in rectangles, circles or triangles, and this calculator gives the total in cubic yards, cubic feet, cubic metres and litres. Pick a material to see the weight too.

How it was worked out
  1. Area: 12 ft × 10 ft = 120 ft²; × 4 in (0.333 ft) deep = 40 ft³
  2. 40 ft³ ÷ 27 = 1.48 yd³

Common use cases

  • Order concrete, gravel, mulch or topsoil by the yard
  • Check a delivery or a contractor's quantity
  • Work out how much a dumpster or truck load holds
  • Convert measurements in feet and inches to yards

How to use

  1. Enter the length and width in feet and the depth in inches.
  2. Switch the shape to a circle, a triangle or a known area if you need to, and add more areas for complicated spaces.
  3. Read the cubic yards, along with cubic feet, cubic metres and litres.
  4. Choose a material to see the weight in tons, and add a price per yard for a cost.

FAQ

How do I calculate cubic yards?

Multiply length × width × depth in feet to get cubic feet, then divide by 27. If the depth is in inches, divide it by 12 first, or use length × width × inches ÷ 324.

How much does a cubic yard cover?

About 324 ft² at 1 inch deep, 162 ft² at 2 inches, 108 ft² at 3 inches, 81 ft² at 4 inches and 54 ft² at 6 inches.

How many cubic feet are in a cubic yard?

27: three feet by three feet by three feet. A cubic yard is also 0.7646 m³, about 765 litres.

How much does a cubic yard weigh?

It depends on the material: roughly 600 lb of wood mulch, about 2,200 lb of dry topsoil, 2,700 lb of gravel and over 4,000 lb of concrete. Choose a material in the calculator to see the figure it uses.
