The math

  1. Area: 80.0 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic yards: 80.0 × 0.250 ÷ 27 = 0.74 yd³.
  4. Tons: × about 1.4 tons per yard = 1.0 tons.

The gravel calculator does this for any size.

Chicken Run tips

Chickens scratch, so a run floor of washed stone 3 to 4 inches deep holds up better than bare soil. Grade the run so water runs out of it, and hose or rake the stone clean as needed.

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.

Getting it delivered

Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. 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.

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

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.
