Quantity calculators for the jobsite

Calculators

Every calculator shows its assumptions under the result. A figure without its mix, its waste allowance and its limits is no use on a jobsite.

Cement bags, a stack of tiles, a plasterboard sheet, a bucket and a trowel arranged on a site pallet

A calculator gives you a quantity of material, not a sign-off on a structure. Anything carrying a building is a structural calculation and may be subject to inspection.

Concrete and mortar

How many bags of cement for your slab, assumptions included.

Tiles and adhesive

Tiles, bags of adhesive, grout and spacers, by tile format.

Plasterboard partition

Boards, track, studs, screws, tape and compound, centres included.

Timber decking

Boards, joists and screws, from joist spacing and board width.

Loft insulation

Bags of blown wool or rolls for a slope, from the pack size you enter.
