Plan wall quantities, openings and economical purchase options.
In your browserExample dimensions only. Confirm your actual brick or block face size and joint width before ordering.
Enter the wall size and the visible face size of your brick or block. Estimate one face layer only (not wall thickness). Door/window areas can be entered directly or calculated from their measurements.
Use when whole units cannot be shared between walls. Counts round up per wall before pack rounding; this still does not model cuts or bonds.
Each row rounds up independently. These rows add to the required count only when separate-wall rounding is selected.
Enter the same product’s actual supplier prices. Compare loose units, full packs, and a mixed order if the supplier permits it.
Enter at least one supplier price to compare purchase costs.
One delivery charge applies to each alternative. No labour, mortar, taxes or supplier minimums are inferred. Mixed ordering is shown only when enabled. Costs use the required count including waste; the full-pack option also includes pack-rounding extras.
Areas display up to six decimal places; tiny values use scientific notation. Counts round up from validated decimal inputs without discarding positive remainders.
Net area is the sum of wall rectangles minus openings. Module area = (face length + vertical joint) × (face height + horizontal joint). Divide net area plus waste by the module area and round up, then round to full packs if requested.
Approximate single-layer face estimate. Depth, bond, corners, returns, piers, edge joints, courses, cuts and reusable offcuts are not modelled. Units are pooled across walls. Joint modules include an edge allowance that may differ from an actual layout. Check a course plan and supplier dimensions before ordering; this is not a structural design or certification.
