Example Data Table
Brick (L×W×H) Joint H/V Approx. Bricks/m² Approx. Bricks/ft²
190×90×90 mm 10/10 mm ≈ 50 ≈ 4.65
230×110×70 mm 10/10 mm ≈ 52 ≈ 4.85
US Modular 7.625×3.625×2.25 in 3/8 in ≈ 74 ≈ 6.9
Figures are indicative; use the calculator with your exact sizes for precise results.
Formula Used
  1. Net Area = Gross Area − Openings Area.
  2. Gross Area (mode LH) = Length × Height × Walls.
  3. Brick face area = (Brick Length + Vertical Joint) × (Brick Height + Horizontal Joint).
  4. Raw bricks = Net Area ÷ Brick face area.
  5. Pattern factor accounts for cuts and layout complexity.
  6. Bricks incl. waste = ceil(Raw bricks × Pattern × (1 + Brick Waste%)).
  7. Auto thickness = Wythes × (Brick Width + Vertical Joint) + Cavity.
  8. Wall volume = Net Area × Wall Thickness.
  9. Total brick volume = Bricks incl. waste × (Brick L × W × H).
  10. Mortar volume ≈ max(0, Wall volume − Total brick volume) × (1 + Mortar Waste%).
  11. Mortar bags = ceil(Mortar volume ÷ Bag yield).
  12. Weights = Volume × Density (brick and mortar separately).
  13. Pallets/straps = ceil(Bricks ÷ size) with leftover counts.
  14. Costs = Bricks × Cost/brick + Bags × Cost/bag.
All dimensions are converted to a consistent system internally before calculation.
How to Use
  1. Choose Metric or Imperial and your preferred area mode.
  2. Enter wall dimensions or direct net area, then add openings.
  3. Select a brick size preset, bond pattern, and joint thicknesses.
  4. Set wythes and cavity; enable auto thickness or type manually.
  5. Pick material densities and mortar yield or set custom values.
  6. Enter waste, costs, pallet and strap sizes, then click Calculate.
  7. Save or load project presets, export CSV or PDF as needed.
FAQs

Different bonds require more cuts and partials. We apply a small multiplier to raw counts to reflect added pieces and breakage for typical layouts.

It sets wall thickness automatically from the number of wythes, brick width, joints, and any cavity. Disable auto to enter a custom thickness instead.

We divide total bricks by your pallet or strap size. Results show required counts using ceiling division and leftover bricks for the final pallet or strap.

Clay, sand-lime, and concrete bricks have different densities. If your supplier lists a value, use that. Otherwise select the closest preset or enter a custom value.

No. Yields vary by brand and mix. Use the closest preset or the yield on your product datasheet for best accuracy.
