Landscaping & Driveway Calculators
Bulk aggregate and surfacing is sold two ways — by volume in cubic yards and by weight in tons — and these calculators give you both from a length, width and depth. Start with the material: the Gravel and Crushed Stone calculators cover general driveway and drainage stone, the Road Base Calculator sizes the compacted sub-base beneath a driveway or patio, and the Asphalt Calculator works in tons because that is how the plant sells it. For landscaping, the Mulch and Landscape Rock calculators use realistic bed depths and a light waste allowance. The Cubic Yard Calculator is the plain volume tool for anything ordered by the yard, with no material assumptions at all. Weight always comes from a bulk density shown on the page that you can replace with your quarry's tons-per-yard figure.

Gravel Calculator
Gravel by volume and by delivered weight for driveways, paths and fill.
Cubic Yard Calculator
Convert a length, width and depth into cubic yards, cubic feet or cubic metres.
Crushed Stone Calculator
Crushed stone by volume and weight. Shares the density question with the Gravel Calculator.
Gravel Driveway Calculator
Gravel for a driveway of a given length, width and depth, by layer.
Road Base Calculator
Road base / crusher-run quantity for a sub-base layer.
Landscape Rock Calculator
Decorative rock by volume and weight for a landscaped bed.
Mulch Calculator
Mulch in cubic yards or bags for a bed of a given area and depth.
Excavation Calculator
Bank (in-situ) excavation volume and the larger, swollen loose volume once soil is dug out, plus an estimated weight.
Topsoil Calculator
Topsoil by volume and by delivered weight for a lawn, bed or fill area from its area and depth.
Bituminous Prime & Tack Coat Calculator
Bituminous prime coat or tack coat material for a paved area from its application rate.
Landscaping & Driveway Guides
How to Calculate Gravel Needed for a Project
Gravel is calculated by volume like concrete, but ordering by weight (tons) means factoring in the specific material's density.
How to Calculate Gravel for a Driveway
A gravel driveway is usually built in layers with a greater total depth than a path, to support vehicle loads over time.
How to Calculate Mulch Quantity
Mulch quantity is bed area times the desired depth, converted to cubic yards for bulk orders or bags for smaller beds.
How to Calculate Paver Sand and Base Material
A paver installation needs a compacted base layer and a bedding sand layer — two separate volume calculations, not one combined figure.
How to Calculate Excavation Volume
Excavation volume follows the same length × width × depth logic as a concrete slab, but real sites often need sectioning for varying depth.
How to Calculate Topsoil Quantity
Topsoil quantity follows the familiar area × depth formula, with typical depths depending on whether you're leveling, filling, or starting a lawn.
Prime Coat vs Tack Coat: What's the Difference?
A prime coat bonds a granular base to the first asphalt layer; a tack coat bonds one asphalt layer to another. They're not interchangeable.
