The math

  1. Area: 160.0 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic yards: 160.0 × 0.250 ÷ 27 = 1.48 yd³.
  4. Tons: × about 1.4 tons per yard = 2.1 tons.

The crushed stone calculator does this for any size.

Stone for a greenhouse

A stone floor drains spilled water, holds some heat and is easy to rake clean. Many growers use about 3 inches of pea gravel or washed stone over fabric, with paver or concrete stepping paths if they roll carts.

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.

Getting it delivered

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. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. Round up by about 10 percent for compaction and uneven ground.

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.

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.
