The math

  1. Area: 100.0 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic yards: 100.0 × 0.250 ÷ 27 = 0.93 yd³.
  4. Tons: × about 1.35 tons per yard = 1.2 tons.

The gravel calculator does this for any size.

Dog Run tips

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.

Before the stone goes in

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. 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.

Measuring the area

Measure length and width in feet at a few points and use the largest figures, since real sites are rarely square. For odd shapes, split the area into rectangles and circles, work out each one and add them together. Depth is the number most people underestimate: drive a stake, run a level string and measure down to the dug-out surface in several spots.

Planning the cost

Stone is usually priced per ton or per cubic yard, and delivery is often a separate charge based on distance. A full truckload can cost less per ton than a partial one, so it can pay to combine projects. Ask whether the quote includes tax, delivery and any small-load fee before you compare yards.
