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 tons results.

What it does – You input the shed base dimensions (length, width in feet and depth in inches) and the tool instantly returns three useful measures: total cubic feet, cubic yards, and an approximate tonnage. Knowing the exact volume prevents ordering too little material, which can delay construction, or too much, which wastes money. The cubic‑feet figure is handy for on‑site checks, while cubic yards match how gravel is sold. The ton estimate uses the industry standard 1.4 US tons per cubic yard, giving you a realistic weight for delivery planning. Read the results: cubic feet → raw volume, divide by 27 for cubic yards, multiply cubic yards by 1.4 for tons. You can also compare the tonnage with your truck’s payload capacity to avoid overload. Use these numbers to place an accurate order.

Pro tips

  • Add 5‑10% extra for compaction loss.
  • Round up to the nearest whole cubic yard when ordering.
  • Order by tons only if the supplier sells by weight.
  • Double‑check depth measurement; a common mistake is using feet instead of inches.

Real-life examples

  • A homeowner building a 10 ft × 12 ft shed needs to know how much gravel to order for a 4‑inch base.
  • A DIY landscaper preparing a garden shed foundation wants to estimate delivery weight for a truck.
  • A contractor quoting a client for a shed base wants a quick, accurate volume to include in the bid.

Case study

Mike entered his 8 ft × 10 ft shed dimensions with a 3‑inch depth and instantly saw 2.2 cubic yards (≈3 tons). He ordered 3 cubic yards, avoiding a shortfall and saving $45 on excess material.

Frequently asked questions

How do I convert the calculator’s result to the amount of gravel bags I need?
Multiply the cubic yards by the bag coverage listed on the bag; most 50‑lb bags cover about 0.05 cubic yards.
Why does the ton estimate differ from the supplier’s weight?
The calculator uses a standard 1.4 US tons per cubic yard; actual weight can vary with moisture and stone size.
Can I use the tool for a concrete pad?
The volume calculation works for any material, but the weight factor (1.4 tons) is specific to gravel.
What if my depth is in centimeters?
Convert centimeters to inches (1 cm ≈ 0.39 in) before entering the depth.
Do I need to include a waste factor?
Yes, add 5‑10 % to the cubic yards to cover compaction and off‑cuts.
