Gravel Calculator
Box volume for crushed stone or gravel. Cubic yards divide cubic feet by 27. Optional tons use a density in lb/ft³ you type. This is coverage, not a concrete mix design.

How to estimate gravel coverage
- Enter length, width, and depth for the area you will cover.
- Pick units. Depth is often inches of stone on a driveway or path.
- Enter waste from 0 to 50 percent for compaction and extra.
- Optional: type density in pounds per cubic foot to see tons. Confirm with a quarry. Estimate only.
Crushed stone volume
Rectangular coverage, not concrete mix
| Volume | L × W × D with waste |
|---|---|
| Cubic yard | 27 cubic feet |
| Tons | ft³ × density (lb/ft³) / 2000 |
| Density | Optional. You type lb/ft³. |
| Not computed | Gradation, base course design, or psi |
| Advice | Estimate only. Not a structural design. |
How gravel volume and tons are computed
Edges convert to feet. Volume is the product times (1 + waste/100). Cubic yards divide by 27. If density is set, tons are cubic feet times lb/ft³ divided by 2000.
Crushed stone versus concrete
This page covers loose stone. It does not batch cement, sand, and aggregate into a mix. Concrete volume is the concrete calculator. Organic cover is mulch.
Estimate only
Compaction, moisture, and stone size change how far a load goes. A supplier ticket wins. Area without depth is square footage. This is not code approval.
Use cases
A driveway lift, a French drain trench approximated as a box, or a patio base. Irregular beds need extra rectangles you add yourself.
Limits
Length, width, and depth must be greater than 0. Waste stays from 0 to 50. Blank density skips tons. CZNull does not receive the numbers.
