Calculating the amount of stone needed for your project depends on whether you measure volume for driveways and walls or square footage for walkways and facades.
Your stone project requirements change based on shape, with rectangular projects needing length, width, and height measurements while cylindrical projects need radius and height calculations.
Measure your project area carefully before purchasing stone to avoid running short mid-project or overspending on excess materials you won't use.
Hiring a local masonry professional keeps your measurements accurate and helps you select the right stone type for driveways, patios, and retaining walls.

How Much Stone Is Needed for Common Projects?
This article covers crushed stone and stone used for flat projects like stone pathways or facades. Almost all stone projects will fit into these two categories. The table below shows estimated stone requirements for common projects.
| Project | Measurements | Stone Requirements |
|---|---|---|
| Retaining wall | 10 ft. x 2 ft. x 3 ft. | 60 cu. ft. or 2.2 cu. yd. |
| Footpath | 20 ft. x 3 ft. x 4 in. | 20 cu. ft. or 0.8 cu. yd. |
| Patio base | 12 ft. x 12 ft. | 48 sq. ft. |
| Gravel driveway | 40 ft. x 10 ft. x 4 in. | 134 cu. ft. or 4.9 cu. yd. |
| French drain | 30 ft. x 1 ft. x 1 ft. | 30 cu. ft. or 1.2 cu. yd. |
| Firepit base | 6-ft. diameter x 3 in. | 7.1 cu. ft. or 0.3 cu. yd. |
There are some important things to keep in mind:
1 cubic yard is 3x3x3 feet (27 cubic feet in a cubic yard).
1 cubic foot is 12x12x12 inches (1,728 cubic inches in a cubic foot).
All volume is shown as a unit to the third power (example: ft³, m³, in³).
How to Calculate Stone Requirements

Most stone projects are standard rectangular ones like driveways, drains, and walls. Use the following formula to calculate the volume of stone required:
Volume of a Rectangle = Length (in feet) x Width (in feet) x height (in feet)
For cylindrical projects, use the following formula:
Volume of a Cylinder = π x Cylinder Radius (squared) x Cylinder Height
To find the radius, measure from one end of the circle to the other and divide by two. If you can’t measure straight across, wrap a measuring tape around the cylinder to find the circumference. Then, use the following formula to find the radius: radius = circumference / (2 x π).
How to Measure for Volumetric Projects
Retaining walls, chimneys, drains, and other projects commonly require calculations that result in cubic measurements (volume amounts). For projects with hard angles like rectangles and squares, you’ll always need three measurements: the length, width, and height. For pillars and other cylindrical projects, you’ll only need the height and radius.
How to Measure Stone Facade Projects
For projects where you’ll just need to cover something—wall, walkways, et cetera—you only need square footage requirements. Assuming you’ll be using a flat stone like flagstone, you’ll need two measurements for your project: the length and height.
For triangles, measure the length of the triangle’s base, multiply by the height from the base to the tip of the triangle, and then divide by two.
Who to Hire to Measure and Install Stone
Homeowners interested in stone projects should talk to a local masonry pro. They’ll be able to accurately determine stone requirements, which stone is best for your project, and provide an accurate quote for completion.
