Gravel Calculators
Last updated .
Start with the stone if the ticket already names it. #57, clean 3/4, pea, and 1 inch gravel on this site start at 1,600 kg/m³, which is 1.35 short tons per cubic yard. 304 starts at 1,920 kg/m³ (1.62 short tons). Crusher run, limestone, and 411 start at 1,700 kg/m³ (1.43 short tons). Class 5 stays at 2,400 kg/m³ because that page treats it as the heavy end.
Start with the project if you know the shape and not the quarry name. A driveway, French drain, walkway, shed pad, pool pad, or patio surface has its own page. The shape tools at the bottom are for a circle or a triangle when none of the project pages fit. Decorative river rock, landscape rock, and lava rock are not driveway base.

Guides
- Gravel sizes
ASTM and AASHTO size numbers next to 304, 411, Class 5, and crusher run, with a calculator for each product this site has.
- Pea gravel vs crushed stone
Drainage, compaction, and walkability, and which jobs belong to rounded pea versus angular stone.
- Gravel driveway depth
Base, middle, and top layers, which size goes in each, and how crown and maintenance differ from a quantity calculator.
- French drain gravel
Stone size, fabric wrap, and how bedding and cover share the trench. Yards stay on the French drain calculator.
- Gravel under pavers
Base depth for a patio, walk, or driveway, the bedding sand, and compaction lifts.
- Shed base: gravel or concrete
Drainage, frost, and pad size for the same footprint, with no prices and no local permit list.
- Winter gravel for ice
Angular grit under 3/8 inch versus salt, and why a road rate per mile is not a driveway dose.
- Spring driveway prep
Reshape the crown and cut out potholes before new stone. Yards stay on the driveway calculators.
