What is the Gravel Calculator?
Estimate gravel volume and weight in tons for driveways and paths. Order the right amount the first time. These construction and DIY calculators estimate materials for common home projects and include sensible waste allowances.
How to use the Gravel Calculator
- Enter your length, your width, your depth, your density.
- Results update automatically as you type; you can also press Calculate.
- Read the output: cubic yards, weight.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With length = 30 ft, width = 10 ft, depth = 4 in, density = 1.4 tons/yd³, the Gravel Calculator returns cubic yards: 3.70; weight: 5.19 tons.
Tips for better results
- Add 5–15% for waste, cuts and breakage depending on the material.
- Measure twice and round up when buying — returns are easier than second trips.
- Coverage figures vary by product, so check the label or spec sheet.
⚠️ Material estimates are approximate. Follow local building codes and manufacturer instructions.
