Gravel Volume Calculator

How to use this calculator

1. Enter length and width in feet.
2. Enter depth in inches and the material density (tons per cubic yard).
3. See cubic yards and tons required; add 5–10% for waste when ordering.

Inputs explained

Length/Width

Project dimensions in feet (driveway, pad, trench run, etc.).

Depth

Desired gravel depth in inches.

Density (tons/yard)

Weight per cubic yard of your aggregate; ask your supplier for exact numbers.

When to use it

• Sizing gravel deliveries for driveways, parking pads, or drainage trenches.
• Comparing material weights across products (pea gravel vs crusher run).
• Budgeting deliveries by tonnage and yardage before ordering.

Tips & cautions

• Add 5–10% for compaction and grading; softer subgrades may need more.
• Different aggregates have different densities—confirm with your supplier for accurate ton estimates.
• Break irregular areas into rectangles, total the yards, then apply density.
• Assumes rectangular areas and uniform depth; complex shapes need segmentation.
• Does not include waste factor automatically—add it manually when ordering.
• Density is an estimate; wet or packed material can weigh more.

FAQs

How much extra should I order?

Add 5–10% to account for compaction, settling, and measurement error.

Does density change?

Yes—pea gravel, limestone, and crusher run vary. Ask your supplier for exact tons/yard.

Can I enter meters instead of feet?

Inputs are in feet/inches. Convert to feet first for accurate results.

What if my area isn’t rectangular?

Break it into smaller rectangles or approximate with average dimensions, then total the yards and add waste.
