How to use it
- Enter length and width in feet, depth in inches
- Click calculate
- Review cubic yards, tons, and cubic feet
- Add 10% waste before ordering
This calculator tells you exactly how much 3/4 crushed gravel your project needs. Enter the length and width of the area in feet, plus the depth in inches. The tool returns cubic yards, approximate tons, and cubic feet — all instantly.
Why it matters: Buying too little means delays and extra trips. Buying too much wastes money. The 1.4 tons-per-cubic-yard estimate gives you a reliable baseline for ordering.
How to read it: Cubic yards is the standard trade measurement. Tons helps you compare supplier quotes. Cubic feet is useful for smaller spot-checks. Multiply your result by 1.10 to add a 10% waste buffer for spills and grading.
No formulas to memorize. Just the dimensions of your space and the density constant of 1.4 tons per cubic yard.
Pro tips
- Add 10% waste allowance for spillage and grading
- Round up to the nearest half-yard when ordering
- Confirm depth with your supplier — compacted vs loose varies
- Never order exact amounts; always round up to avoid shortages

Case study
A homeowner needed gravel for a 15×30 ft patio at 4 inches deep. Before using the calculator, they ordered 5 yards and ran short. After calculating, they got 5.55 yards, added 10% waste, and ordered 6 yards — completing the job in one delivery, no waste.
