Worldwide wall material estimator
Bricks, blocks, mortar, cement, sand and cost for a whole job, not just one wall. Any region - UK, US, Europe, Australia, South Africa or a custom size - solid or cavity walls, multiple sections in one estimate.
United Kingdom, United States, Europe, Australia or South Africa's standard sizes, or type in a custom brick or block face size - one calculation covers all of them.
Add as many wall sections as the job needs, each with its own material, and see running totals across the whole thing - no re-entering numbers per wall.
Model a full cavity wall - separate outer and inner leaf materials, plus a wall-tie estimate - or a solid single or full-thickness wall.
Mortar volume converts straight into bags of cement and tonnes of sand for the mix ratio you choose, with a wastage allowance built in.
Optional per-material pricing for a rough cost, extra units for corners and returns, and a coursing check so you know before ordering if a wall lands on a whole course.
Full packs plus loose units for ordering, a name for each wall (front elevation, garage, side return), and a one-click copy or standalone HTML export of the whole job to keep, print or send on.
A layout that spreads across a wide window instead of one narrow column, plus a light/dark toggle that remembers your choice next time you open the app.
Load a realistic example to see how it works - it rotates through a handful of different jobs (cavity, blockwork, imperial, more) so it's not the same one twice in a row - or clear everything back to a single blank wall in one click.
Buildxact is a well-known cloud estimating and takeoff platform used by builders for whole-job quoting. It's built for running a business's estimating pipeline, not for a quick brick-and-block sense-check - here's how a focused, one-off desktop tool compares.

A single-skin brick front and a brick-and-block cavity return, with prices filled in so the job gets a materials cost as well as counts.
The course count is the detail worth noticing: the app tells you when a wall height lands on a whole number of courses and when it doesn't, which is the difference between a tidy top course and a row of cuts. Change the region to US Modular or Australian brick and every count is recalculated for that coordinating size. Open the browser edition to try it with your own figures.
Read the guide: How many bricks per m²? - bricks and blocks per m², openings, waste, ties and mortar.
No - use it straight from your browser, on a phone, tablet or PC, with no sign-up. It works offline once it has loaded, and you can add it to your home screen or desktop like an app. There is also a Windows desktop version in the Microsoft Store if you prefer an installed app.
Not at all. Brick & Block Calculator never asks you to create an account, and everything you enter stays on this PC. Registering is optional and only used to tell you about updates.
Site managers, estimators, bricklayers, small trade contractors and self-builders who want a quick, worldwide-capable materials estimate before they order - not a replacement for a full takeoff on a complex job.
Yes - pick United Kingdom, United States, Europe, Australia or South Africa, or type in a custom brick or block size. The same calculation applies everywhere, in metric or imperial.
Yes - add as many wall sections as a job needs and see running totals across all of them, and choose a full cavity wall build-up (separate outer and inner leaf, plus a wall-tie estimate) or a solid wall for each section.
