Gravel & Mulch Calculator
Calculate cubic yards and tons of gravel, mulch, sand, or topsoil.
How to calculate gravel, mulch, or sand by the yard
Measure the area length and width in feet. For irregular shapes, break it into rectangles and add the results.
Enter the desired depth in inches. Decorative gravel is typically 2–3 inches deep; drainage gravel needs 4–6 inches.
Select your material type. Density varies — pea gravel and crushed stone weigh more per cubic yard than mulch or topsoil.
Read cubic yards for ordering from a landscape supplier, and tons for delivery pricing (most trucks quote by the ton).
Common uses
- Ordering landscape gravel for a driveway or walkway
