Single-wythe rectangular wall, fully filled joints, ideal solid bricks. Bond pattern, cavities, frogs, breakage and mixed masonry change quantities.

Your calculation, step by step

No black boxes
  1. Net wall area = 200 − 20.
  2. Module face = (7.625 + 0.375) × (2.25 + 0.375) in²; round up after adding waste.
  3. Mortar estimate = single-wythe gross volume minus ideal solid brick volume, before waste.

Save up to three scenarios, then change your inputs to compare the possibilities.

How to use this calculator

  1. Enter your own values in the labeled fields. Check the units and assumptions before comparing results. Only the fields needed for your selected calculation mode are shown.
  2. Your answer updates automatically. Review the calculation steps to see exactly how it was calculated.
  3. Copy, share, save, or download your result. Saved inputs stay on this device.

How the calculation works

Bricks = ceil(net area / jointed face module × allowance)

The model treats a single-wythe wall as a regular repeating brick face. Openings reduce net area. Mortar volume is the ideal wall volume less solid bricks before waste; voids, bond patterns and actual brick cavities can materially change it. Review the units, period and assumptions before comparing scenarios. Displayed values are rounded, while the underlying calculation retains its available precision.

A worked example

For 100 ft², 12 × 6 inch bricks with no joints or waste require 100 × 144 / 72 = 200 bricks.

Reading your result

Use the main result together with its units and supporting figures. Display values are rounded; calculations keep their underlying precision. A change in inputs or assumptions can change the answer. Compare the step-by-step working with your intended use before relying on an estimate.
