Crushed Stone Calculator
Plan your crushed stone project with confidence. Enter the dimensions of your area and select the stone type to get precise volume measurements in cubic feet, cubic yards, and weight in tons. Includes cost estimation based on your local stone prices.
Length of the area to cover
Desired depth of crushed stone layer
Different stone types have slightly different densities
Typical range: $25-$80 per ton delivered
Cubic Feet = Length (ft) x Width (ft) x Depth (ft)
Cubic Yards = Cubic Feet / 27
Weight:
Tons = Cubic Yards x Density Factor
Density: 1.3 to 1.5 tons per cubic yard
Standard Factor:
1 cubic yard approx. 1.4 tons (average)
Volume = 40 x 12 x 0.333 = 160 cu ft
Cubic Yards = 160 / 27 = 5.93 cu yds
Tons = 5.93 x 1.4 = 8.30 tons
@ $45/ton: 8.30 x $45 = $373.50
Order approximately 9 tons to be safe.
How much crushed stone do I need for a driveway base?
For a driveway base, you typically need 4-6 inches of compacted crushed stone. Calculate the volume by multiplying length x width x depth in feet, then divide by 27 to get cubic yards. Multiply by 1.4 to convert to tons. For a 20 ft x 12 ft driveway at 4 inches deep: (20 x 12 x 0.333) / 27 = 2.96 cubic yards x 1.4 = 4.15 tons.
What is the difference between crushed stone 57 and 67?
Crushed stone 57 is 1/2 to 1 inch in size and is the most popular choice for driveways, drainage, and concrete mix. Crushed stone 67 is smaller, approximately 3/4 inch and down to fine particles, making it better for walking paths and as a base for pavers. Both are angular materials that interlock when compacted.
How deep should crushed stone be for different applications?
Recommended depths vary by use: Driveway base: 4-6 inches. Walking paths: 2-3 inches. French drains: 4-6 inches. Paver base: 4-6 inches. Under a shed or small building: 4 inches. For heavy vehicle traffic areas like RV parking: 6-8 inches. Always compact in 4-inch lifts for proper settling.
How do I calculate crushed stone in tons vs cubic yards?
Crushed stone typically weighs 1.35 to 1.5 tons per cubic yard, depending on the stone type and moisture content. For estimating, use 1.4 tons per cubic yard. To convert, multiply your cubic yards by 1.4 to get tons. Most suppliers sell by the ton, so this conversion is essential for ordering.
