Formula
Cubic yards = length (ft) × width (ft) × depth (ft) ÷ 27. Depth is often measured in inches, so 6 inches = 0.5 ft.
Estimated tons = cubic yards × material density (tons per cubic yard). Truckloads = cubic yards ÷ truck volume capacity, or tons ÷ truck weight capacity, rounded up.
Example
An area 27 ft × 10 ft at 12 inches deep = 270 ft³ ÷ 27 = 10 cubic yards. Gravel at about 1.4 tons per cubic yard ≈ 14 tons.
Material density assumptions
Densities in this tool are approximate loose-material values. Moisture, compaction and gradation can change weight by 10–20% or more. If your supplier gives a density, enter it in the optional density field.
Volume or weight — which limits the truck?
Light materials such as mulch usually fill a truck bed before reaching legal weight. Dense materials such as wet sand or stone usually hit the weight limit first. Choose the capacity unit (cubic yards or tons) that matches how your truck is rated.
Frequently asked questions
How many tons are in a cubic yard of gravel?
Roughly 1.4 tons for typical loose gravel, but it varies with stone size and moisture.
Should I order extra material?
Many contractors add 5–10% for compaction, uneven grades and waste. Confirm with your supplier.
Are the truck capacities Contractor Transport's equipment?
No. Enter your own truck capacity; the calculator does not describe any specific fleet.
