Construction Calculator
Rule-of-thumb site math, reviewed October 2026 — first-pass material estimates, not a bill of quantities or a code check. Confirm with your contractor or engineer.

The count is wall area ÷ the face area one brick occupies with its mortar joint, rounded up: 10 m² at 0.092 m² per brick needs ceil(10 ÷ 0.092) = 109 bricks. The joint is the point — a nominal 190 × 90 mm brick with a 10 mm joint occupies 200 × 100 mm of wall, and entering the bare brick size under-counts every course.
Measure the wall, enter the per-brick face area including one mortar joint, and read a single-leaf count. Then adjust reality upward: full-brick (double-leaf) walls need roughly twice as many, openings come off the area, and cuts plus breakage want a 5% buffer on top. Brick size and bond vary by region, so confirm the face size with your supplier, not memory.
It does not output mortar volume, price the wall, or check structural thickness rules — a material count for one leaf, to be multiplied and buffered by site judgement.
Single leaf only — mortar volume and wall thickness rules excluded.
The per-brick area allows for a mortar joint, but it does not output the volume of mortar separately.
It estimates a single leaf. Multiply for thicker walls, and add wastage for cuts and breakages.
About 11 per m² at 0.092 m² per brick (10 ÷ 0.092 ≈ 109 for 10 m²) — but always compute from your actual brick-plus-joint size.
