How to use it
- Enter the bed length in feet, width in feet, and depth in inches.
- Click the Calculate button.
- Read the results in cubic yards, tons, and cubic feet.
What it does – The Garden Bed Dirt Calculator takes the length and width of your raised bed in feet and the depth in inches, then instantly shows how much soil you need in three useful units: cubic yards, tons (using the industry standard 1.3 US tons per cubic yard), and cubic feet. Why it matters – Knowing the exact volume prevents over‑ordering costly soil or ending up short and having to scramble for more. How to read – Cubic yards is the quantity most suppliers quote; convert to tons by multiplying by 1.3 for a weight estimate; cubic feet helps you visualize the space in familiar terms. You can also compare the tonnage with delivery truck capacities to plan the best loading schedule. The calculator works on any device, so you can measure on the job site and get results on your phone instantly.
Pro tips
- Add 5‑10% extra for settling and compaction
- Round up to the nearest 0.1 cubic yard for easier ordering
- Check supplier weight limits; 1 cubic yard ≈1.3 tons
- Measure depth from the top of the bed, not the soil surface

Case study
Emily planned a 12‑ft by 8‑ft raised bed 8 in deep. The calculator told her she needed 1.78 cubic yards (≈2.3 tons) of soil, so she ordered exactly that amount, avoiding a $45 over‑order and a last‑minute trip for more soil.
