Brick Calculator
Professional masonry estimator. Calculate bricks, mortar, sand, cement, and costs for single or double-skin walls. Includes global brick database.
1. Dimensions & Structure
2. Brick Selection
3. Openings
4. Logistics & Cost (Optional)
About
Professional estimation requires more than simple area division. This tool is engineered for contractors and serious DIY builders who need to account for structural realities. Unlike standard calculators that assume a single layer of bricks, this engine supports Single Skin (half-brick thick), Double Skin (one-brick thick), and Cavity Wall configurations.
The calculation logic integrates a volumetric analysis of mortar joints, distinguishing between the nominal size (includes joint) and actual size of the masonry unit. It computes logistics data including total weight (for vehicle payload limits) and pallet estimation. The database includes over 50 standard unit sizes across North America, Europe, and Oceania, ensuring accuracy regardless of regional standards. Wastage factors are applied to the final procurement order, not the structural area, to ensure the site never runs dry.
Formulas
The estimator uses a multi-stage logic to determine material lists. First, it calculates the raw brick count based on the chosen wall construction type (skins).
Load weight is critical for logistics. It is approximated using average densities (ρ) for clay and mortar.
