Easily estimate the quantity of bricks and mortar required for any wall construction with our free online calculator. Input your wall dimensions, brick sizes, and joint thickness to get precise material estimates, helping you plan your project efficiently and avoid material waste.
Formula:
To estimate the number of bricks and mortar volume, the calculator uses the following logic:
- Total Wall Volume (Vwall) = Wall Length (L) × Wall Height (H) × Effective Wall Thickness (Teff)
- Effective Wall Thickness (Teff) = (Number of Skins × Brick Width) + ((Number of Skins - 1) × Mortar Joint Thickness)
- Bricks per Square Meter = 1 / ((Brick Length + Mortar Joint Thickness) × (Brick Height + Mortar Joint Thickness))
- Total Bricks (B) = Bricks per Square Meter × Wall Length (L) × Wall Height (H) × Number of Skins × (1 + Waste Factor)
- Volume of One Brick (Vbrick) = Brick Length × Brick Height × Brick Width
- Total Mortar Volume (M) = (Vwall - (Total Bricks (without waste) × Vbrick)) × (1 + Waste Factor)
All dimensions are converted to meters for consistent volume calculation.
