How to use it

  1. Enter length in feet
  2. Enter width in feet
  3. Enter depth in inches
  4. Read cubic yards, cubic feet, and ton estimate

The Soil Raised Bed Calculator turns the three dimensions you enter—length, width, and depth—into the three quantities you care about: total cubic feet of soil, how many cubic yards that equals, and an approximate weight in US tons. Knowing the volume helps you buy the right amount of soil, avoid costly over‑orders, and plan delivery logistics. The weight estimate uses the industry‑standard 1.3 tons per cubic yard, so you can match it to truck capacities or budget line items. Results appear instantly, so you can tweak dimensions on the fly and see how each change impacts material needs. Read the cubic‑yard figure for ordering bulk soil, the cubic‑foot number for bag calculations, and the ton estimate for heavy‑lift planning. You can also round up to the nearest half‑yard to give yourself a safety margin.

Pro tips

  • Add 5‑10% extra volume for settling
  • Round cubic yards up to the nearest 0.5 for bulk orders
  • Compare the ton estimate to your truck’s payload before scheduling delivery
  • Double‑check depth conversion (inches to feet) to avoid under‑estimating

Real-life examples

  • A homeowner planning a 4 × 8 ft vegetable bed 12 in deep
  • A community garden organizer ordering soil for multiple raised beds
  • A landscaper estimating material for a new patio border with raised planting strips

Case study

Maria entered a 6 ft × 5 ft × 10 in bed and saw 1.1 yd³, 30 ft³, and 1.4 tons. She ordered 1.5 yd³ of soil, avoiding a $50 over‑order and finished planting the same day.

Frequently asked questions

How do I convert depth in inches to feet?
The calculator does the conversion automatically; just enter the depth as shown on your plan.
Why is the weight shown in tons, not pounds?
Bulk soil is usually sold by the cubic yard, and industry standards estimate 1 cubic yard ≈ 1.3 US tons.
Can I use the results to order bagged soil?
Yes—divide the cubic‑foot total by the bag size (e.g., 2 ft³) to know how many bags you need.
What if my bed isn’t a perfect rectangle?
Break the shape into rectangles, calculate each, then add the results.
Do I need to account for soil compaction?
The 1.3 ton per cubic yard factor already includes typical compaction for loose fill.
