Volume and tonnage calculator →The math
- Area: 28.3 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic yards: 28.3 × 0.333 ÷ 27 = 0.35 yd³.
- Tons: × about 1.4 tons per yard = 0.5 tons.

Where round stone areas work
A round gravel area is easy to lay out with a stake and string at the center. Set flexible edging along the line and lay fabric inside before the stone goes in. For a fire pit area, keep combustibles well away and check local burn rules.

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. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
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.
