Pick a material and enter your area and depth to get cubic yards, tons and coverage — for gravel, soil, mulch, sand and more.
How the yard calculator works
“How many yards do I need?” is the most common landscaping question, and this yard calculator answers it for any material. Choose what you’re ordering, enter the area and depth, and it returns cubic yards, cubic feet, tons and the coverage.
Because different materials weigh different amounts, the tonnage updates with the material you pick.
Using the calculator
- Select the material you’re ordering.
- Enter the area and depth, rectangular or round.
- Read the cubic yards and tons for your delivery.
The formula
cubic yards = (length × width × depth) ÷ 27
tons = cubic yards × material density ÷ 2000

Questions people ask about this
What does a “yard” of material mean?
It’s a cubic yard — a 3×3×3-foot volume, equal to 27 cubic feet. It’s the standard unit for bulk landscape materials.
How many yards do I need?
Multiply your area in square feet by the depth in feet, then divide by 27. The calculator does this once you enter the numbers.
Why does tonnage change with material?
Gravel, soil and mulch have very different weights, so a cubic yard of each weighs a different number of tons.
