How many bricks you need

Estimate bricks for one wall layer, with allowance for mortar joints and openings.

Your numbers

Brick count wey di model estimate

—

Na one face layer alone; bonding pattern, corners and structural wall thickness need separate quantity calculation.

Formula

Use N = ceil[(A−O)(1+w)/((l+j)(h+j))]. A and O na wall and opening areas for m²; brick face dimensions l, h and joint width j need conversion to m. w na waste fraction and ceil dey round up.

Estimate bricks for one wall layer, with allowance for mortar joints and openings.

Example wey show the calculation

Full wall area (m²): 10
Area of di openings (m²): 0
Length of brick face (mm): 190
Height of brick face (mm): 90
Di mortar joint (mm): 10
Allowance for waste (%): 10

Brick count wey di model estimate: 550
