Gravel Calculator
Calculate gravel volume, weight, and cost for your construction and landscaping projects
Calculate Gravel Requirements
Typical depth: 2-4 inches for paths, 4-6 inches for driveways
Default: 1680 kg/m³ (105 lb/ft³) for typical gravel
Gravel Requirements
Formula: Volume = Area × Depth, Weight = Volume × Density
Calculation: 0.00 m² × 0.000 m = 0.00 m³
Cost Estimation
Example Calculation
Driveway Gravel Project
Project: 100 ft² driveway, 2 inches deep
Dimensions: 10 ft × 10 ft × 2 in
Area: 10 × 10 = 100 ft² = 9.29 m²
Depth: 2 inches = 0.167 ft = 0.051 m
Gravel density: 1680 kg/m³ (105 lb/ft³)
Calculation
Volume = 9.29 m² × 0.051 m = 0.474 m³
Volume in cubic yards = 0.474 × 1.308 = 0.620 yd³
Weight = 0.474 m³ × 1680 kg/m³ = 796 kg
Result: 0.620 yd³ or 0.796 tons of gravel
Common Gravel Types
Pea Gravel
¼ to ⅜ inch, smooth, rounded
Great for pathways and drainage
Crushed Stone
¼ to 2 inches, angular
Best for driveways, compacts well
River Rock
1 to 3 inches, smooth
Decorative landscaping
Depth Guidelines
Project Tips
Add 5-10% extra material for waste and compaction
Consider truck access for delivery
Prepare base with landscape fabric
Compact in layers for best results
Understanding Gravel Calculations
Volume Calculation
The volume of gravel needed is calculated by multiplying the area to be covered by the desired depth. For rectangular areas, multiply length × width × depth. For irregular shapes, calculate the total area first.
Weight Calculation
Weight is determined by multiplying volume by the gravel's density. Different types of gravel have different densities, ranging from 1,200 to 2,000 kg/m³ (75 to 125 lb/ft³).
Common Conversions
- •1 cubic yard ≈ 0.714 tons of gravel
- •1 ton covers approximately 100 ft² at 2" depth
- •1 cubic meter = 35.3 cubic feet
Project Planning
Proper planning ensures you order the right amount of gravel. Consider the project type, expected traffic, drainage requirements, and aesthetic preferences when choosing gravel type and depth.
Types by Application
Driveways
Crushed stone, 4-6 inches deep, angular for compaction
Pathways
Pea gravel, 2-3 inches deep, smooth for walking
Drainage
Larger stones, varies by application, good permeability
