Volume and tonnage calculator →The math
- Area: 200.0 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic yards: 200.0 × 0.250 ÷ 27 = 1.85 yd³.
- Tons: × about 1.35 tons per yard = 2.5 tons.

Building the dog run base
For a dog run, rounded stone such as pea gravel is gentle on paws and drains fast. Lay it about 3 inches deep over fabric and edge the run so the stone stays put.

Prep
Clear vegetation, rake the soil level and compact it. Lay fabric overlapped at the seams and set edging before spreading the stone.
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. Decomposed granite packs into a firm, natural path when wetted and compacted in thin lifts. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
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.
Common mistakes
The most frequent problem is ordering for the finished depth without allowing for compaction, which can shrink a loose layer by 10 to 20 percent. Another is skipping fabric on soft soil and watching the stone vanish into the mud over the first wet season. Spreading everything in one thick layer instead of compacted lifts also leaves a soft, rutted surface.
