How to use it
- Enter length in feet
- Enter width in feet
- Enter depth in inches
- Read cubic yards, tons and cubic feet results
Enter the patio length, width, and desired depth. The calculator converts those dimensions to cubic feet, then to cubic yards (the standard ordering unit for bulk gravel). It also multiplies cubic yards by 1.4 to give an approximate tonnage, so you know the weight you’ll be handling and the cost you’ll be quoted. Knowing cubic yards helps you order the right amount from suppliers, while tons let you compare delivery fees that are often weight‑based. The results appear instantly, letting you adjust dimensions on the fly and avoid costly over‑ordering or shortfalls. Use the numbers to budget, schedule delivery, and communicate clearly with contractors or DIY teams. If you’re planning a multi‑level patio, run the calculator for each section and add the totals. The tool also shows the volume in cubic feet, which is handy when you need to compare against bagged sand or stone that is sold by the cubic foot.
Pro tips
- Add 5‑10% extra for spillage and compaction
- Round up to the nearest whole cubic yard for ordering
- Order by tons if the supplier charges weight‑based delivery
- Double‑check depth before finalizing the calculation

Case study
Mike wanted a 12 ft × 8 ft patio 4 in deep. Using the calculator he saw he needed 2.4 cubic yards, about 3.4 tons of gravel. He ordered exactly that amount, avoided a $150 over‑order, and the patio was ready on schedule.
