How to use it

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

What it does – The Gravel Fill Calculator turns the dimensions of your area into three practical measures: cubic yards (what most suppliers quote), tons (the weight you’ll pay for), and cubic feet (useful for on‑site planning). Why it matters – Ordering too little means extra trips and delays; ordering too much wastes money and fills your truck. How to read the results – Cubic yards is the volume to request from the vendor, tons is the estimated weight (1 yard ≈ 1.3 tons), and cubic feet helps you visualize the depth across the whole surface. The calculator also shows the result in cubic feet so you can double‑check the numbers against your own manual conversion. No need for spreadsheets or guesswork; the figures update the moment you change any input.

Pro tips

  • Add 5‑10% extra volume to cover compaction and spillage.
  • Round up to the nearest half‑yard to simplify ordering.
  • Order by weight (tons) if the supplier charges per ton.
  • Double‑check depth entry; inches, not feet, are required.

Real-life examples

Case study

Maria needed 1.5 yd³ of gravel for a 12 ft × 8 ft patio at 4 in depth. Using the calculator she saw she actually required 1.6 yd³ (≈2.1 tons) and ordered the correct amount, avoiding a costly second delivery.

Frequently asked questions

How do I convert the result to tons?
Multiply the cubic yards by 1.3 US tons per cubic yard; the calculator does this automatically.
My depth is in centimeters—can I use this tool?
Convert centimeters to inches (1 in = 2.54 cm) before entering the depth.
Do I need to include a waste factor?
Yes, add 5‑10 % to the cubic‑yard result to cover settling and spillage.
Is the weight estimate accurate for all gravel types?
The 1.3 ton per cubic yard estimate is an industry average; actual weight may vary slightly.
Can I save or share the results?
The tool provides a printable summary that you can copy or email after the calculation.
