Using a circle of stone
Circles show up around fire pits, under swing sets, around trees and as seating areas. Steel or paver edging keeps the round shape crisp and holds loose stone in place. For a fire pit area, keep combustibles well away and check local burn rules.

Ordering and delivery
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. 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.
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.
