How to use it
- Enter patio length in feet.
- Enter patio width in feet.
- Enter sand depth in inches.
- Click Calculate to see cubic yards, cubic feet, and tons.
Calculate Sand Needed lets you input the length, width, and depth of your patio and instantly see three useful measures: total cubic feet of sand, the equivalent in cubic yards (the unit suppliers use), and an approximate weight in US tons. Knowing the cubic yards helps you order the right amount without costly over‑orders, while the ton estimate lets you compare delivery fees that are often weight‑based. The tool converts depth from inches to feet, multiplies the three dimensions for cubic feet, then divides by 27 to get cubic yards and multiplies by 1.3 tons per cubic yard for weight. Use the results to plan material purchase, budget, and site preparation confidently. If the calculator shows 1.5 cubic yards, order at least 2 cubic yards to allow for settling and spillage.
Pro tips
- Add 5‑10% extra sand to cover compaction and spillage.
- Round up to the nearest half‑yard for easier ordering.
- Order sand by the cubic yard; suppliers charge by weight using 1.3 tons per yard.
- Double‑check depth conversion from inches to feet before calculating.
Real-life examples
- Planning a 12 × 15 ft patio with a 3‑inch sand base.
- Estimating sand for a backyard fire pit surrounded by a 8 × 8 ft patio.
- Renovating a walkway that requires a 2‑inch sand layer over 20 ft of length.
Case study
Mike entered his 10 ft × 12 ft patio and a 4‑inch depth, getting 1.5 cubic yards (≈2 tons). He ordered 2 cubic yards, avoiding a costly second delivery and finished the project on budget.
