Brick Calculator
Calculate brick quantity for masonry: standard, 1.5×, double size. Mortar consumption for wall and facade.
Total wall length or perimeter in meters
Masonry height in meters
Masonry thickness in bricks: 0.5 — partition or facing, 2 — load-bearing wall
Standard 250×120×65, 1.5× 250×120×88, or double 250×120×138 mm
Mortar joint thickness in millimeters (typically 8–12 mm)
Calculation formula
Bricks = Area × Rate (pcs/m²); Mortar = Area × Thickness × 0.025 m³
Wall area is multiplied by the tabular brick rate based on brick type and wall thickness. Mortar volume is taken as 0.025 m³ per brick layer of thickness at a 10 mm joint.
About the brick calculator
The brick calculator estimates how many bricks and how much mortar you need for a wall of a given length and height. Pick the brick type — standard, 1.5×, or double — and the masonry thickness from half a brick to two bricks, and the calculator instantly shows piece count and mortar volume in m³.
It is useful for building load-bearing house walls, cladding facades, putting up interior partitions, or laying stoves and fireplaces. Knowing the consumption rate up front makes it easier to buy material with a sensible reserve and plan the masonry budget.
All math runs locally in your browser without any data leaving your device and without registration. Use the brick calculator for free — for self-build projects, apartment renovation, or commercial sites.
Calculator benefits
All brick sizes
Standard, 1.5×, and double — per-m² rates are substituted automatically based on the chosen brick size.
Mortar estimate
Beyond brick count, the calculator shows masonry mortar volume in m³ and its weight in kg.
Any wall thickness
Supports 0.5, 1, 1.5, and 2 brick walls — from cladding and partitions to load-bearing structures.
FAQ
What is the difference between a standard and 1.5× brick?
A standard brick is 65 mm tall and a 1.5× brick is 88 mm tall, with the same 250×120 mm footprint. One square meter of single-brick masonry takes about 102 standard or 78 1.5× units, so the larger format covers area faster and uses slightly less mortar.
How much mortar do you need per 1 m² of masonry?
At a 10 mm joint, one square meter of single-brick wall consumes about 0.05 m³ of mortar, 1.5-brick wall about 0.075 m³, and 2-brick wall about 0.1 m³. By weight that is roughly 90–180 kg of cement-sand mortar per square meter.
Does brick masonry need reinforcement?
Yes — for load-bearing walls it is recommended every 4–6 rows using 50×50 mm masonry mesh or 4–6 mm rebar. Piers, areas under windows, columns, and lintel bearings should always be reinforced.
What load does a brick wall put on the foundation?
One square meter of single-brick wall weighs about 240 kg, 1.5-brick about 360 kg, and 2-brick about 480 kg including mortar. When sizing a strip or slab foundation, add slab, roof, and live loads on top of this masonry weight.
How much extra brick should I order?
Typically 5–10% on top of the calculated quantity covers breakage on delivery, cuts at openings, and batch defects. For facing brick, 10% is safer so the whole facade comes from one batch and shades match.
How are windows and doors accounted for?
Subtract the total opening area from the wall area before entering dimensions into the calculator. For a 30 m² wall with 6 m² of openings, set length and height so that their product equals 24 m².
