How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read cubic yards, cubic feet, and tons results.
The 57 Gravel Calculator lets you input the exact dimensions of a driveway, patio, or garden path and instantly shows the volume in cubic feet, the equivalent in cubic yards, and an approximate weight in tons. Knowing the yardage helps you order the right amount from the supplier, avoiding costly over‑orders or shortfalls that delay a project. The cubic‑foot figure reflects the raw space you’ll fill; divide by 27 to see how many full yards that represents. Multiply the yardage by 1.4 to get a quick estimate of tons, which many carriers quote. Use the results to compare quotes, plan delivery logistics, and budget accurately. The calculator updates in real time, so you can experiment with different depths to see how material needs change.
Pro tips
- Add 5‑10% extra for compaction and breakage.
- Round up to the nearest whole yard; suppliers often sell by the yard.
- Order a little more than the ton estimate if the truck capacity is limited.
- Double‑check that depth is entered in inches, not feet.
Real-life examples
- A homeowner planning a 12 × 20 ft driveway with 4 in depth.
- A landscaper estimating gravel for a 30 × 40 ft garden path at 3 in depth.
- A contractor needing material for a 50 × 60 ft parking strip with 6 in depth.
Case study
Mike needed gravel for a 15 × 30 ft patio at 4 in depth. Using the calculator he saw he required 0.74 cubic yards, about 1 ton. He ordered 1 ton, saved $200 on excess material and finished on schedule.
