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

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.

Before the stone goes in

Remove sod and roots, level the area and slope it slightly for drainage. Install edging so the stone stays inside the footprint.

Ordering and delivery

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. Pea gravel is small and rounded, comfortable underfoot, and needs edging because it rolls. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.

Planning the cost

Quarries and landscape suppliers set their own prices, and they change by region and season. Get the price per ton, the delivery fee and the minimum order. If two products will both work, compare cost per square foot at your depth rather than cost per ton.

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.
