Gravel Calculator
Estimate the cubic yards — and the weight in tons — of gravel, crushed stone or sand for any project.
Last reviewed 2026-06-06
Gravel, stone and sand are sold by weight or by the cubic yard, but you measure your project by area and depth. This calculator bridges the two — and gives you the weight so you can get an accurate quote from a supplier.
Enter the length, width and depth of the area, then pick your material. Different materials weigh different amounts, so we apply the right density to estimate tons (or tonnes) as well as volume.
How to use the Gravel Calculator
- Measure the length and width of the driveway, path or patio base.
- Choose a depth — 2 inches for a top-up, 4 inches or more for a new driveway base.
- Select the material so the weight estimate uses the right density.
- Read off the cubic yards and tons, then add 10–15% for compaction.
Frequently asked questions
How much gravel do I need for a driveway?
Measure length × width × depth. A new gravel driveway usually needs a total depth of about 4–6 inches, often in two layers. Enter your dimensions above and add 10–15% extra for compaction.
How many tons of gravel are in a cubic yard?
It depends on the material. Crushed stone is roughly 1.5 US tons per cubic yard, pea gravel about 1.4, and sand around 1.35. This calculator applies the correct density once you select a material.
Should I order gravel by the ton or by the yard?
Either works — suppliers often quote both. Volume (cubic yards) tells you if it will fit the space; weight (tons) is how it is usually priced and loaded. The calculator gives you both so you can order confidently.
Why add extra for compaction?
Loose gravel compresses as it is driven on or tamped down, losing volume. Adding 10–15% means the finished, compacted depth still matches what you planned.
