How Much Gravel Do You Need? A Practical Way to Estimate
Gravel Made Simple
You don’t need to be an engineer to estimate gravel — you just need a simple method that gets you close enough to plan.

Step 1: Measure length and width
Measure your driveway area in feet.
Example: 200 ft long × 12 ft wide
Step 2: Choose depth (in inches)
Common finished depths vary by goal and traffic. For estimating, choose a depth like:
- 2 inches (light resurfacing)
- 3–4 inches (more substantial refresh)
Convert inches to feet:
- 2 inches = 2/12 = 0.167 ft
- 3 inches = 3/12 = 0.25 ft
- 4 inches = 4/12 =
0.333 ft
Step 3: Calculate cubic feet
Formula:
Length × Width × Depth (ft) = cubic feet
Example (200 × 12 × 0.25) = 600 cubic feet
Step 4: Convert to cubic yards
There are 27 cubic feet in 1 cubic yard.
Cubic feet ÷ 27 = cubic yards
- Example:
600 ÷ 27 = 22.22 cubic yards
Step 5: Add waste/settling buffer
Gravel settles and real driveways aren’t perfect rectangles.
Add 10–15% as a buffer.
- Example:
22.22 × 1.10 = 24.44 cubic yards
One more practical note
Suppliers often sell by ton. Converting yards to tons depends on the material type and moisture.
If you want a rough planning number, ask your supplier: “How many tons per cubic yard for this stone?” Then convert based on their spec.
