Formula Used
- Effective face = (face-dimension-A + head joint) × (face-dimension-B + bed joint).
- Face area per brick = effective face (in²) ÷ 144 → ft².
- Bricks per ft² = 1 ÷ face area per brick; for bonds, weighted by header/soldier proportions.
- Total bricks = ceiling( wall area × bricks per ft² × (1 + total wastage%) ).
- Brick volume (each) = length × width × height (in³) ÷ 1728 → ft³.
- Wall volume = wall area (ft²) × wall thickness (ft).
- Wet mortar volume ≈ max( wall volume − total brick volume, 0 ).
- Dry mortar volume ≈ wet volume × 1.33 (bulking/voids allowance).
- Cement volume = dry volume × cement parts ÷ total parts.
- Sand volume = dry volume × sand parts ÷ total parts.
Pattern allowances apply typical cut waste; adjust Base Wastage to suit site conditions.

FAQs
Counts are driven by effective face. Patterns like English and Flemish blend header faces, which are smaller, raising bricks/ft² compared with pure stretcher bonds.
Each pattern adds a typical cut allowance (e.g., herringbone). The total wastage equals Base Wastage plus the pattern allowance shown in results.
Yes. Set the frequency to place a header course every N stretcher courses to match drawings.
No. They load sizes in either inches or millimeters as listed. Use the Units toggle for your inputs.
We include common examples such as US modular and utility, UK 215×102.5×65 mm, Pakistan 9×4.5×3 in, and similar widely used formats.
Mortar volume is based on wall thickness and brick volume. Herringbone typically increases cut waste only, reflected in the allowance.
They are planning estimates. Verify against shop drawings, manufacturer data, and site constraints.

We convert dry volume using a 1.33 factor, apply the mix ratio, assume 1440 kg/m³ for cement density, and divide by 50 kg per bag.
Increase wall thickness to include multiple wythes or calculate each wythe separately and sum totals.
