Brick Calculator

Brick Calculator estimates brick, pallets, and mortar allowance for general brick walls with openings. Enter job dimensions in U.S. customary units, adjust supplier assumptions, and get purchase-ready quantities instantly.

HOW IT WORKS

Formula and assumptions

Subtract openings from wall area, divide by the actual unit face plus the mortar joint module, apply waste, and round up.

Unit dimensions are actual face dimensions before the mortar joint is added.
Openings are entered as total square feet.

FIELD CHECK

Before you order

Enter the actual modular or nonmodular brick face and mortar joint used in the bond pattern.

Worked example

Example: with wall length 24 ft, wall height 8 ft, doors and windows 42 sq ft, waste allowance 7 %, the brick calculator returns 1,101 bricks for bricks to buy. The supporting check is pallets: 3 pallets. Replace the prefilled measurements and supplier assumptions with the project values before ordering.

WHEN TO USE IT

Best use of this calculator

Use the result as a planning estimate, then verify field measurements and product-specific data before ordering or building.

INPUTS EXPLAINED

What each input means

Wall length: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Wall height: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Doors and windows: Enter the project value in sq ft.
Actual unit face length (without joint): Enter the measured value and choose the matching unit (in, ft, cm, mm).
Actual unit face height (without joint): Enter the measured value and choose the matching unit (in, ft, cm, mm).
Mortar joint: Enter the measured value and choose the matching unit (in, ft, cm, mm).
Waste allowance: Enter the project value in %.
Units per pallet: Enter the project value used by the calculation.
Price per unit: Enter the project value in $.

COMMON MISTAKES

Checks that prevent bad estimates

Mixing units or entering a measurement in a different unit than the selected field unit.
Using a planning default when the exact manufacturer or supplier specification is available.
Rounding intermediate measurements too early instead of rounding the final purchase quantity.
Ignoring waste, compaction, cuts, laps, settlement, or full-package rounding where the project requires them.

SOURCES & REVIEW

How this estimate is supported

The implemented formula, assumptions, and worked example on this page are the calculator-specific reference. BuildYard's broader rules are documented in the Calculation Methodology and Sources & References.

For material density, coverage, yield, dimensions, package quantity, price, and other product-specific values, the current manufacturer or supplier specification should override a planning default.

COMMON QUESTIONS

Brick Calculator FAQ

What does the Brick Calculator calculate?

It converts the measurements for general brick walls with openings into the buying units normally used for brick, pallets, and mortar allowance, with the relevant waste, package, weight, or cost outputs shown on the result card.

How accurate is this brick calculator?

The geometry is calculated from the values you enter. Final ordering accuracy still depends on field measurements, supplier density or coverage, product dimensions, compaction, cuts, and the selected allowance.

What should I verify for general brick walls with openings?

Enter the actual modular or nonmodular brick face and mortar joint used in the bond pattern. Confirm the selected product, field conditions, and purchasing increments before placing the order.

Should I round the result up?

Yes for indivisible buying units such as bags, sheets, bundles, pallets, boxes, bars, and truck loads. The calculator rounds those purchase quantities up automatically.
