Landscaping calculators

Work out how much bulk material to order for beds, paths, lawns and patios, by the yard, the ton or the bag.

Tons and cubic yards of gravel, crushed stone or sand for any mix of areas, by depth and material density.

Cubic yards or bags of mulch for every bed, topping up what is already there to the depth you want.

Cubic yards, tons or bags of topsoil or fill for lawns, beds and grading, by area and depth.

Square feet, pieces and pallets of sod for any mix of lawn areas, with waste, weight and the cost to buy and lay it.

Pounds and bags of grass seed for a new lawn or overseeding, by grass type, from university extension seeding rates.

Pavers to order for a patio or walk, plus the gravel base, bedding sand and edge restraint under them.

Blocks, caps, base gravel and drainage stone for a segmental block retaining wall, course by course.

Cubic yards, cubic feet and cubic metres for any area and depth, the unit bulk material is sold in.

Ordering bulk material

Measure every area. Break odd shapes into rectangles, circles and triangles and add them up. The calculators take any mix.
Pick the depth. Volume is area times depth, so an extra inch over a big area is a lot of material.
Convert to what the yard sells. Landscape yards sell by the cubic yard, quarries by the ton. The conversion is the material's density, which the gravel and topsoil calculators let you set.
