Gravel Calculator

The driveway math quarries assume you can't do.

Gravel is ordered by the ton but planned by the yard, and the conversion depends on the material. This calculator handles the full chain: dimensions to cubic feet to cubic yards to approximate tons using the standard crushed-stone density — so you can order once, order right, and spot a bad quote instantly.

Why people use this

Driveway and path projects live here. People use this to order once and order right — gravel is sold by the ton but planned by the yard, and the conversion is exactly where DIY estimates go wrong. Landscapers use it to sanity-check supplier quotes.

How it works

1. Enter the project length and width in feet.
2. Enter depth in inches: 2–3 for paths, 4 for driveways over a compacted base, 6+ for heavy vehicles.
3. The calculator computes cubic yards and converts to tons at ~1.4 tons per yard (typical crushed stone).
4. Add 5–10% for compaction and waste before ordering.

Common questions

How much does a ton of gravel cover?

Roughly 100 square feet at 2 inches deep, or 80 square feet at 3 inches, for standard crushed stone. Pea gravel and lava rock differ — ask the supplier for their density if ordering specialty stone.

How deep should a gravel driveway be?

Three layers is the professional standard: 4 inches of large base stone, 4 inches of mid-size, and 2–3 inches of surface gravel. For a single-layer refresh, 2–3 inches over existing compacted gravel is typical.

How many cubic yards fit in a dump truck?

A standard tandem dump truck carries 10–14 cubic yards; a single-axle around 5–6. Weight is often the real limit — a full load of gravel can exceed 10 tons.
