Volume and tonnage calculator →The math
- Area: 176.7 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic yards: 176.7 × 0.250 ÷ 27 = 1.64 yd³.
- Tons: × about 1.4 tons per yard = 2.3 tons.

Where round stone areas work
A round gravel area is easy to lay out with a stake and string at the center. Set flexible edging along the line and lay fabric inside before the stone goes in. For a fire pit area, keep combustibles well away and check local burn rules.

Getting it delivered
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Pea gravel is small and rounded, comfortable underfoot, and needs edging because it rolls. Round up by about 10 percent for compaction and uneven ground.
Measuring the area
Use a long tape and measure each side twice. If the ground slopes, measure depth at the high and low ends and average them. Irregular outlines can be broken into simple rectangles, triangles and circles; add the pieces for the total square footage before converting to tons.
Tools for the job
A flat shovel, a steel rake, a wheelbarrow and a rented plate compactor cover most residential pads. A landscape rake or the back of a rake levels the top layer, and a long straightedge or a level string shows high and low spots before the final pass.
