How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the depth in inches.
- Read the cubic yards, cubic feet, and tons results.
This free online calculator turns the three dimensions of your garden bed—length, width, and depth—into three practical measures: cubic feet, cubic yards, and an approximate weight in US tons. Knowing the cubic yards tells you how many bulk bags or truckloads to order, while cubic feet is useful for smaller bags. The ton estimate, based on a constant 1.3 tons per cubic yard, helps you budget for delivery costs that often charge by weight. Simply type your measurements, hit calculate, and the tool instantly shows the three results. Use the cubic‑yard figure to match supplier specifications, the cubic‑foot number for bag‑size calculations, and the ton value to confirm you’re not under‑ordering for a healthy garden.
Pro tips
- Add 10% extra volume to cover settling and compaction.
- Round up the final cubic‑yard number; suppliers sell whole yards.
- Order soil in the unit (bags or bulk) that matches the cubic‑yard result to avoid waste.
- Double‑check depth conversion: inches ÷ 12 = feet before multiplying.
