How the gravel calculator works

  1. Area — length × width for rectangles, π × r² for circles, ½ × base × height for triangles. All in feet.
  2. Volume — area × depth (inches ÷ 12) = cubic feet. Divide by 27 to get cubic yards.
  3. Weight — cubic yards × the material's density. Crushed stone and gravel run about 1.4 tons per cubic yard, crusher run about 1.5, sand 1.3–1.35, fill dirt about 1.2 and topsoil about 1.1.
  4. Compaction & waste — base materials compact when rolled, and some always ends up on the edges. We add 10% by default.
  5. Truckloads — a full load is up to 18 tons; the calculator rounds up.

How deep should gravel be?

Project Typical depth
Refresh an existing gravel driveway 2"
Walkway, path or patio top layer 2–3"
New driveway top layer 3–4"
Driveway or parking base (crusher run / #411) 4–6"
Heavy trucks or equipment pads 6–8"
French drain / drainage trench full trench depth

Quick reference

  • 1 cubic yard of gravel covers about 108 sq ft at 3" or 81 sq ft at 4".
  • 1 ton of gravel covers about 75–80 sq ft at 3".
  • A 60 × 12 ft driveway at 4" needs ≈ 8.9 yd³ ≈ 12.4 tons (+10% ≈ 13.75 tons).

FAQ

Gravel Calculator FAQ

How many tons of gravel are in a cubic yard?

Most crushed stone and gravel weighs about 1.4 tons per cubic yard (2,800 lb). Dense-graded base like crusher run is closer to 1.5 tons. The calculator uses the right density for each material.

How much does 1 ton of gravel cover?

Roughly 75–80 square feet at 3" deep, or about 60 square feet at 4" deep.

Should I order extra?

Yes — add about 10% for compaction and spillage on base materials. Running short means a second delivery fee; a small surplus is easy to spread.

Can I send the estimate for a quote?

Yes. Click "Use this estimate for my quote" and the numbers are attached to your request automatically.
