Worldwide concrete volume estimator

Concrete Volume Calculator

Concrete volume for slabs, footings and columns, from dimensions - with cement, sand and aggregate to order for the whole job, not just one pour at a time.

Metre2 Concrete Volume Calculator showing a pours list, a selected slab's dimensions, and job totals across two pours

Slabs, footings and columns

Rectangular slabs, strip footings, and round or square columns - each with its own dimension fields and a quantity for identical repeats, like fence posts or footings.

Any mix ratio, worldwide

1:1.5:3 structural, 1:2:4 general, 1:3:6 mass fill, or a custom ratio - 25kg, 50kg or 94lb (US) cement bags, metric or imperial units.

Every pour, one job total

Add every slab, footing and column in a job and see cement, sand and aggregate to order for the whole thing, not a separate tally per pour.

Cement, sand, aggregate and water

Bags of cement, tonnes of sand and aggregate, and water by the litre - from a standard dry-volume factor and material densities, with a waste allowance built in.

Named pours and exports

Name each pour for a job that reads back clearly, then copy a plain-text summary or export the whole job as a standalone HTML file to keep, print or send on.

A pours list, not a form to scroll through

Every pour sits in a list on the left - click one to edit it on the right, with job totals always visible at the bottom. Light/dark theme remembers your choice.

Frequently asked questions

Do I need to install anything to use Concrete Volume Calculator?

Concrete Volume Calculator is a Windows desktop app, free to try from the Microsoft Store.

Does my Concrete Volume Calculator account work with Vector and Forma?

Yes - Concrete Volume Calculator uses the same shared Metre2 account as Vector, Forma and every other Keystone app. Sign in once and it works everywhere.

Is this a substitute for a qualified engineer's mix design?

No - it's a quick sizing sense-check from generic, rounded reference values (a 1.54x dry-volume factor, standard cement/sand/aggregate densities), not a certified mix design. Always verify against the applicable standards and get structural pours designed and checked as required in your jurisdiction.

Does it work outside the UK?

Yes - metric or imperial units, and a choice of common mix ratios (1:1.5:3, 1:2:4, 1:3:6, or a custom ratio) with 25kg, 50kg or 94lb cement bag sizes.
