Gravel Calculator
Estimate how many cubic yards or meters of gravel you need for a level layer, plus approximate weight for hauling.
Step 1: Units
Step 2
Enter project measurements
Use decimals if needed (e.g. 3.5).
Step 3
How to use this calculator
Measure the coverage rectangle and average depth you want after compaction. Deeper sections can be averaged or split into multiple runs.
What the math is doing
Volume is length × width × depth. Weight multiplies volume by a typical bulk density for that material.
How to measure
Stake the area and run a string line for straight edges. Depth is from existing grade to finished grade.
Frequently asked questions
Do I need geotextile?
It reduces mixing with soil below on soft sites; ask your supplier.
Compacted vs loose volume?
Depth should be the finished compacted thickness you want to see.
How much extra?
Use the waste field for fluff factor and uneven subgrade.
Ton vs yard ordering?
Use the weight line to cross-check truck payloads.
