How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches.
  4. Click Calculate to see cubic yards, tons, and cubic feet.

What it does – the calculator turns the dimensions of your pea‑gravel area into three practical measures: cubic yards (the unit suppliers use), approximate tons (based on 1.4 US tons per cubic yard), and cubic feet (useful for on‑site checks). Why it matters – ordering too little means extra trips and delays; ordering too much adds unnecessary cost and waste. How to read – cubic yards is the volume you’ll quote to a vendor, tons gives a weight estimate for transport, and cubic feet lets you verify the space fills as expected. Just input length, width, and depth, hit calculate, and you have the numbers to order confidently.

Pro tips

  • Add 5‑10% extra for compaction and spillage.
  • Round up to the nearest 0.1 yd³ for ordering.
  • Compare supplier pricing per ton vs per cubic yard.
  • Double‑check depth; a common mistake is entering inches as feet.

Real-life examples

  • A homeowner planning a 12 ft × 15 ft patio with a 3‑inch gravel base.
  • A landscaper estimating material for a 200‑sq‑ft garden path 4 in deep.
  • A DIYer needing gravel to fill a 5‑ft × 8‑ft fire pit 6 in deep.

Case study

Jane entered a 10 ft × 12 ft area with a 4‑inch depth, got 1.48 yd³ and 2.07 tons, ordered exactly that amount, and completed her patio without extra trips or leftover gravel.

Frequently asked questions

What depth should I use for a pea‑gravel patio?
Typical patios use 2‑4 in depth; choose the depth that matches your design and load requirements.
Why does the calculator show tons?
Suppliers often price gravel by weight; using 1.4 US tons per cubic yard gives a quick weight estimate for budgeting.
Can I use the results for a rectangular and a circular area?
The tool works for any rectangular footprint; for circles calculate the area first and enter length × width as the equivalent rectangle.
Do I need to account for compaction?
Yes, add 5‑10% extra volume to cover settling and compaction before ordering.
Is the result in cubic feet useful?
Cubic feet helps you visualize the space on‑site and verify that the gravel will fill the intended area.
