The math

  1. Area: 75.0 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic yards: 75.0 × 0.250 ÷ 27 = 0.69 yd³.
  4. Tons: × about 1.4 tons per yard = 1.0 tons.

The gravel calculator does this for any size.

Building the dog run base

Pea gravel is a common dog run surface because it drains and is easy on paws; some dogs dig in it, so edging and a deeper layer help. Rinse the run regularly, and pick stone without sharp edges.

Prep

Clear vegetation, rake the soil level and compact it. Lay fabric overlapped at the seams and set edging before spreading the stone.

Buying the stone

If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Gravel is a broad label, so confirm whether the yard means crushed or rounded stone and whether it carries fines. Round up by about 10 percent for compaction and uneven ground.

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.

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.
