Gravel Calculator
Estimate gravel by area and depth in tons or cubic yards.
Gravel is estimated by volume and then converted to tons. Multiply the area by the depth, converted to feet, to get cubic feet. Divide by 27 to get cubic yards, and multiply by approximately 1.4 to get tons.

How does the gravel calculator work?
Gravel is estimated by volume, then converted to tons. Multiply the area by the depth (converted to feet) to get cubic feet, divide by 27 for cubic yards, and multiply by ~1.4 for tons.
Formula: tons = (L × W × D/12 ÷ 27) × 1.4

What else do people ask about this calculator?
How much gravel do I need for a driveway?
A typical residential driveway uses 4–6 in of gravel. For a 20×10 ft driveway at 4 in, you need about 2.5 yd³ (3.5 tons).
How many tons of gravel in a cubic yard?
About 1.4 tons per cubic yard for average crushed stone. Denser stone (river rock) can be 1.5+ tons/yd³.
How deep should gravel be for drainage?
3–4 in for a top layer; 6+ in for a base beneath pavers or concrete.

Gravel guide
How much gravel you need, what a cubic yard weighs, and which type fits your project.

Weight
Crushed Stone guide
Crushed stone sizes suit different applications: #57 stone is commonly used for drainage, concrete, and paver bases; #8 stone works for fine paver bedding, chip seal, and decorative applications; and ¾″ minus, also called crusher run, compacts into a hard driveway base.
Pea Gravel guide
Pea gravel is smooth, rounded ⅜″ stone commonly used for patios, paths, play areas, dog runs, and drainage. One cubic yard weighs about 2,700–2,800 lb and covers approximately 100 sq ft at a 3″ depth. For walkable surfaces, use a 2–3″ layer and edging to keep the gravel contained.
Limestone guide
Crushed limestone for base, drainage, and agricultural use.
