Direct answer
Estimate the volume occupied by loose stone across a measured area. The result describes space, not the mass of a particular stone, and remains valid without assuming a product density.
Use it for loose stone in borders, drainage zones, paths or landscape layers where the footprint and planned depth are known.
Follow the finished edging rather than the rough excavation. Split curved borders into short measured sections or use circles and triangles where they fit. Keep larger feature-stone zones separate from small graded-stone areas.
Loose landscaping stone includes voids between particles. Its bulk density is not the density of a solid piece of stone.
A circular stone bed has a diameter of 3.6 m and a depth of 60 mm. Its radius is 1.8 m and area is π × 1.8² = 10.178760 m². At 0.06 m depth, volume is 0.610726 m³ before allowance.
The example uses geometry only. It does not insert a density, package size, recommended depth or supplier tolerance.
Suppliers may use stone, chippings, gravel or rock for different products. Record the nominal size, grading, finish and sale unit shown on the quotation. Use supplier package capacity for bag counts.
The tool does not choose a suitable stone, assess drainage or predict how particles will settle. It also cannot infer coverage from a product photograph.
No. Geometry sets volume, but stone size can affect bulk density, settlement and appearance.
No. Enter the capacity printed for the actual bag or container.
