How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches and hit Calculate.
The 0 3 4 Gravel Calculator turns the three dimensions you input—length, width and depth—into three practical quantities: cubic yards, cubic feet and an approximate tonnage. Knowing the cubic yards tells you how many bulk bags or truckloads to order; cubic feet is useful for smaller projects or when comparing material specs; the ton estimate (1 yard ≈ 1.4 US tons) helps you budget weight‑based delivery fees. The tool does the math instantly: it converts depth from inches to feet, multiplies the three dimensions for total cubic feet, divides by 27 for cubic yards, then multiplies by 1.4 for tons. Read the results, round up slightly, and you’ll order the right amount without costly over‑or under‑ordering. Because gravel settles over time, adding a small buffer prevents shortages. The calculator also shows the result in cubic feet, which aligns with many supplier quotes.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up to the nearest whole yard; suppliers sell by the yard.
- Compare the ton estimate with the supplier’s per‑ton price before ordering.
- Double‑check depth; a 1‑inch error changes volume by about 8%.
Real-life examples
- A homeowner planning a new driveway needs to know how much gravel to order.
- A landscaper installing a garden path wants to budget material costs accurately.
- A contractor preparing a base for a patio must order enough gravel to meet code‑specified depth.
Case study
Sam measured his 12 ft × 15 ft patio area at 4 in depth. The calculator showed 2.22 yd³ and about 3.1 tons. He ordered 3 tons, saved $150 by avoiding a second delivery, and finished on schedule.
