THE MATH, MADE SIMPLE

Exactly how we calculate your gravel.

No mysterious formulas or hidden estimates. Your measurements determine volume; your chosen density determines weight.

01 / MEASURE

Calculate area

Length in feet × width in feet = square feet of coverage.

02 / CONVERT

Find cubic yards

Area × depth in inches ÷ 12 ÷ 27 = cubic yards. Add your extra allowance.

03 / COMPARE

Estimate weight and cost

Cubic yards × density = US tons. Compare bulk charges with rounded-up bag costs.

Good to know: Gravel varies by type, moisture, compaction and supplier. If you have an irregular area or a compacted-depth requirement, confirm measurements and order allowances with a qualified supplier. This prototype assumes a rectangular area.
