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.

Enter the length, width, and desired depth of your pea‑gravel area. The tool instantly converts those dimensions to cubic feet, then to cubic yards (1 cubic yard = 27 cubic feet). It also multiplies the yardage by the industry‑standard weight of 1.4 US tons per cubic yard to give an approximate tonnage. Knowing the volume helps you order the right amount, avoid costly over‑orders, and plan delivery logistics. The results are displayed in three units so you can compare with supplier quotes that may list price per cubic foot, yard, or ton. Use the numbers to add a 5‑10 % waste factor, round up to the nearest whole unit, and place an accurate order. You can also save the calculation for future projects or share it with contractors to ensure everyone is on the same page.

Pro tips

  • Add 5‑10% extra for compaction and breakage.
  • Round up to the nearest whole cubic yard or ton for supplier minimums.
  • Order by the unit your supplier quotes (yard, foot, or ton) to avoid conversion errors.
  • Double‑check depth conversion from inches to feet before entering data.

Real-life examples

  • A homeowner planning a new pea‑gravel driveway needs to know how much material to order.
  • A landscaper estimating material for a garden path wants accurate tonnage for delivery pricing.
  • A DIYer renovating a patio wants to compare supplier quotes listed in different units.

Case study

Sarah entered a 12 ft × 8 ft patio with a 3‑inch depth. The calculator showed 2.22 cubic yards, about 3.1 tons. She added a 10% waste factor, ordered 2.5 cubic yards, and avoided a costly over‑order.

Frequently asked questions

How do I convert depth in inches to feet?
Divide the inch value by 12; the calculator does this automatically.
Why does the ton estimate differ from the yardage?
Because each cubic yard of pea gravel weighs roughly 1.4 US tons.
Should I round up the tonnage?
Yes, round up to the next whole ton to cover variations in material density.
Can I use the calculator for other gravel types?
The volume conversion works for any material; adjust the weight per yard if needed.
Is the calculator accurate for irregular shapes?
It assumes a rectangular area; break irregular sites into rectangles and sum the results.
