How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches and hit Calculate.
What it does – The Gravel Calculator turns the dimensions of your area (length, width, depth) into three useful measures: cubic feet, cubic yards, and an approximate tonnage. Knowing cubic yards tells you how many standard 0.5‑yd³ bags or bulk deliveries to order. Tons help you compare pricing between bagged and bulk options, since many suppliers quote weight. How to read the results – Cubic feet is the raw volume. Divide by 27 to see cubic yards (the unit most landscapers use). Multiply cubic yards by 1.4 tons to get an approximate weight. For example, a 10 ft × 5 ft area 4 in deep equals 16.65 ft³, about 0.62 yd³, which is roughly 0.86 tons of gravel. Use the result to order a little extra for compaction and spillage—most professionals add 5‑10 % to the calculated volume. This prevents costly trips back to the supplier.
Pro tips
- Add 5‑10 % extra volume for compaction and spillage.
- Round up to the nearest whole yard for easier ordering.
- Check supplier specifications; some quote weight per yard differently.
- Measure depth in inches carefully—small errors multiply over large areas.
Real-life examples

Case study
Emily wanted a 10 ft × 8 ft patio 3 in deep. Using the calculator she saw she needed 0.74 yd³ (≈1.04 tons). She ordered 1 yard, avoided a second delivery, and finished on budget.
