How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Click Calculate to see cubic yards, tons and cubic feet.
What it does – The calculator turns the dimensions of a gravel pad (length, width, depth) into three practical measures: cubic yards, cubic feet, and an approximate tonnage. Knowing cubic yards lets you order the right amount of material; cubic feet is useful for comparing to other fill specs; tonnage helps you budget for delivery costs that are often priced per ton. The tool automatically converts inches to feet, multiplies the three dimensions for volume in cubic feet, then divides by 27 to get cubic yards and multiplies by 1.4 US tons per cubic yard for a quick weight estimate. Read the results side‑by‑side to avoid over‑ordering or short‑changing your project. The calculator is free, works on any device, and updates instantly as you change numbers, so you can experiment with different depths before finalizing your order.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up the tonnage to the nearest half‑ton when ordering.
- Order a little more than the calculated cubic yards to avoid a second delivery.
- Double‑check depth conversion; 12 in = 1 ft.
Real-life examples
- Homeowner laying a 6‑inch driveway.
- Landscaper filling a garden path 4 in deep.
- DIYer building a patio base 8 in thick.
Case study
Maria needed a 12 ft × 10 ft patio with 6 in depth. The calculator showed 1.78 cubic yards, about 2.5 tons. She ordered 2 tons, saved $40 on material, and completed the patio without a second truck.
