Using a circle of stone
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. Rake the stone level after spreading and add a thin top-up after the first season.

Ordering and delivery
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. #57 is a washed stone of roughly 1/2 to 1 inch with few fines; it drains fast but stays a little loose on its own. 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.
Common mistakes
People often forget that compaction reduces volume, so they come up short. Others order clean, round stone where a packable crushed stone with fines would have stayed put. Finally, dumping the whole load in one pile far from the work area adds hours of wheelbarrow trips.
