Inputs
Example Data
Auto-calculated brick needs for a 3.0 × 2.5 wall (no openings), bed/perpend joints 10 mm, wythe = half-brick.
| Preset | Bricks per m² | Total Bricks (3.0×2.5 m) |
|---|
Formula Used
- Modular Length = Brick Length + Perpend Joint
- Modular Height = Brick Height + Bed Joint
- Bricks per m² (single leaf) = 1 / (Modular Length × Modular Height)
- Net Face Area = Wall Length × Height × Count − Σ(Openings Width × Height × Count)
- Wythe Leaves = {0.5→1, 1.0→2, 1.5→3, 2.0→4}
- Total Bricks (no wastage) = Bricks per m² × Net Face Area × Wythe Leaves
- Total Bricks (with wastage %) = ceil(No‑wastage × (1 + w/100))
- Wall Thickness (for volume) depends on wythe: width, length, width+length, 2×length (plus joints)
- Wall Volume = Net Face Area × Thickness
- Mortar Wet Volume ≈ Wall Volume − Total Brick Solid Volume
- Dry Mortar Volume = Wet × 1.33; Cement Volume = Dry × C/(C+S); Sand Volume = Dry × S/(C+S)
How to Use
- Select Units and enter Wall Length, Height, and count.
- Choose Wythe thickness to reflect wall construction.
- Pick a Brick Preset or enter dimensions and joint sizes.
- Add any Openings like doors or windows; use the “+ Add Opening” button.
- Set Wastage and optional pack size for pallet estimates.
- Enable Mortar estimation to see mortar volume and material breakdown.
- Click Calculate, then export your results as CSV or PDF.
FAQs
Counts are based on modular dimensions including joints and selected wythe thickness. Real‑world workmanship, tolerances, and bond patterns may vary, so keep a prudent wastage allowance.
For planning quantities, bond patterns typically do not change counts significantly when joints are included. Specialty bonds or decorative work may need specific allowances.
Yes. Enable the mortar panel to see wet and dry mortar volumes, cement bags from density and bag weight, and sand volume by your mix ratio.
Add each opening with width, height, and count. Their areas are subtracted from the total wall face area before computing quantities.
Change bed and perpend thicknesses to match your specification. The calculator recomputes the modular brick size and updates bricks per area accordingly.
Yes. Switch units to convert inputs and labels. Metric uses meters and millimeters; imperial uses feet and inches.
