How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the depth in inches and click Calculate.
Use the Garden Soil Calculator to instantly find how much soil you need for any rectangular garden bed. Enter length, width, and depth, and the tool returns the volume in cubic yards, cubic feet, and an approximate weight in tons. Knowing cubic yards helps you order the right amount of bagged or bulk soil, while cubic feet is useful for on‑site mixing. The ton estimate uses the standard 1.3 US tons per cubic yard, so you can budget delivery costs accurately. The results appear instantly, so you can compare supplier quotes or adjust dimensions on the fly. Remember that soil settles, so add a small waste factor. You can also convert the cubic‑foot value to bag counts by dividing by the bag’s coverage. The calculator is free, works on any device, and requires no sign‑up.
Pro tips
- Add 10% extra soil to cover settling.
- Round up to the nearest whole cubic yard for bulk orders.
- Use the ton estimate to compare supplier prices per ton.
- Verify depth conversion; 12 in = 1 ft.
