Gravel Calculator
Estimate the total weight and volume of gravel, crushed stone, or aggregate required for driveways, paths, and sub-bases. Planning for a solid foundation.

Material Overview
Gravel and aggregate are typically sold by weight (tons) or volume (cubic yards). One ton is approximately 2,000 pounds and covers significantly less volume than lighter materials like mulch. Calculating the exact tonnage prevents overpaying for delivery or stalling mid-project.
Density Standard
Most crushed stone has a density of 1.4 tons per cubic yard. However, wet or exceptionally dense stone (like granite) can reach up to 1.5 - 1.6 tons per yard.
Compaction Factor
Loose gravel compacts by 20% to 30% once rolled. If your driveway needs a 4" finished depth, you should order 5" of loose material.
Material Formula
Volume To Weight Logic
Tons = [ (L × W × D) ÷ 27 ] × 1.4
Where Depth (D) is converted from inches to feet (inches ÷ 12).
Popular Aggregate Grades
- #57 Stone: For drainage and French drains
- Crushed Run (ABC): Ideal for driveway bases
- Pea Gravel: Decorative and play areas
- Rip Rap: For erosion control on banks
Usage Pro Tip
Always order "Crushed Run" for any project requiring compaction (like a patio base). The mix of stone dust and 3/4" rock locks together, creating a surface that won't shift under pressure.
