Gravel Calculator
Calculate how much gravel you need for your driveway, walkway, or landscaping project. Enter dimensions and depth to get material estimates.
Select how you're measuring the area.
The length of the area in feet.
The width of the area in feet.
The depth of gravel in inches.
Different gravel types have different densities.
This calculator estimates the amount of gravel needed based on area dimensions and desired depth. Results include cubic yards, tons, and coverage area.
How It Works
Gravel Volume Formula
Volume = (L × W × D ÷ 27)Volume in cubic yards equals length times width times depth (in feet), divided by 27.
Convert depth from inches to feet by dividing by 12
Calculate area in square feet: length × width
Calculate volume in cubic yards: area × depth (in feet) ÷ 27
Important Notes:
- •One cubic yard covers approximately 108 square feet at 3 inches deep
- •Standard gravel weighs approximately 1.4 tons per cubic yard
- •Different gravel types have different densities
- •Always order 10-15% extra for compaction and settling
Worked Example
A rectangular driveway 10 feet by 20 feet, 2 inches deep.
Inputs:
- area Type:rectangle
- length:20
- width:10
- depth:2
- gravel Type:standard
Result:
You'll need approximately 1.23 cubic yards of gravel, weighing about 1.72 tons, covering 200 square feet.
