Gravel Calculator
Calculate gravel or stone volume and optionally estimate mass when density is known.
Gravel or stone volume
Enter area, average depth, and optional waste. The calculator separates base and recommended volume and reports cubic meters, feet, and yards.
Volume = area × depth
Weight only when density is known
Density varies with stone type, grading, moisture, and compaction. Editable gravel (1,700 kg/m³) and crushed-stone (1,600 kg/m³) presets are rounded references; you can enter your supplier's density instead.
Frequently asked questions
How do I measure an irregular area?
Split it into simple shapes, total their areas, and use a reasonable average depth.
Is compaction included?
Not automatically. Adjust dimensions or allowance according to the project specification.
Why is density optional?
Different materials can have very different mass at the same volume.
