Brick count from wall area
Use this brick calculator when the wall area is known and you need a whole-brick planning count. The default is 7 bricks per square foot with 5% waste. Change both inputs when the selected unit, joint, pattern, or job conditions call for something different.
The Brick Industry Association says its Technical Note 10 covers modular and non-modular brick masonry and provides guidelines for estimating material quantities. BIA lists the note in its technical library. That is the right principle for this tool: dimensions and unit choice drive the count.
This is quantity math, not a complete masonry estimate. Mortar, sand, ties, flashing, lintels, reinforcement, scaffolding, delivery, cleanup, and labor remain separate so you can audit the brick count.
How to use the brick calculator
- Measure wall length and height in feet, then multiply them for gross square footage.
- Subtract openings large enough to materially reduce the brick field.
- Enter the resulting wall area.
- Enter the bricks-per-square-foot figure for the selected unit and layout. Use 7 only as the built-in planning default.
- Enter a waste percentage for cuts, breakage, sorting, and field loss.
- Read the rounded whole-brick result.
If the wall is concrete masonry rather than fired clay brick, use the concrete block calculator instead. Unit dimensions and layout are different, so swapping the density input is not a clean substitute.
The calculator uses:
Bricks to order = ceiling(net wall area × bricks per sq ft × (1 + waste % ÷ 100))
The ceiling step rounds any fractional result up to the next whole brick. Keep the three decisions visible: measured area, unit density, and waste. If the brick density changes from 7 to 6.8 or 7.2, update that input rather than hiding the difference in waste.
Brick dimensions, mortar-joint thickness, bond pattern, and special layout conditions affect units per square foot. Seven bricks per square foot is an editable planning value here, not a promise for every product.
Ask the manufacturer or supplier for the takeoff density for the actual brick and joint. Keep field brick separate from corners, rowlock, soldier courses, sills, caps, accent bands, and other special pieces. Those units can have different packaging and lead times.
BIA describes Technical Note 10 as covering basic wall layout, structural and veneer applications, unit sizes, and material estimating. That scope is why product dimensions belong in the count, not in a generic waste factor.
Worked example: 252 square feet of brick veneer
A veneer wall is 32 feet long and 9 feet high, for 288 square feet gross. A large opening removes 36 square feet, leaving 252 square feet.
At 7 bricks per square foot, the base quantity is 1,764 bricks. Applying 5% waste gives 1,852.2, so the calculator rounds the order quantity to 1,853 bricks.
If the supplier takeoff specifies 6.9 bricks per square foot, change the density input. The same area and waste then produce 1,825.74, which rounds to 1,826 bricks. The wall area did not change; the product-specific unit density did.
What the calculator does not include
The output covers field-brick quantity only. Mortar color and quantity, sand, flashing, weeps, anchors, control or expansion joints, reinforcement, scaffolding, weather protection, cleaning, delivery, labor, and equipment need their own estimate lines.
BIA notes that one of its own cladding cost tools excludes mortar costs, mason labor, installation costs, and wasted materials. Its calculator page makes those exclusions explicit. This brick calculator handles waste when you enter a percentage, but it still does not price those other scope items.
If you have not settled the cladding material, the brick vs stone veneer guide covers the broader system choice before you lock a takeoff.
How to handle windows and doors
Use one opening rule across the estimate. Subtract a garage door, storefront opening, or wide window bank when it removes a meaningful area of masonry. Small openings can stay in gross area when cuts, returns, and layout losses consume much of the apparent savings.
Do not subtract every opening and then add a large waste allowance for the same cuts. That can make the adjustment hard to defend. Record gross area, deducted openings, net area, and waste as separate lines so another estimator can follow the takeoff.
Turn the count into an order
Clay brick is often sold by the thousand, and BIA offers a calculator that converts a price per thousand brick into a price per square foot. BIA explains that conversion on its calculator page. For purchasing, also record the manufacturer, color or blend, plant, size, finish, packaging quantity, special shapes, and acceptable delivery lots.
Run separate counts when an elevation mixes products or sizes. Convert the approved whole-brick count to cubes, pallets, or partial packages only after the takeoff is set. Packaging should shape the purchase order, not the area formula.
Once brick, accessories, delivery, labor, and equipment are priced, use the break-even calculator to test how much job revenue the complete cost requires at your target gross margin. A brick count alone cannot answer that business question.

Brick calculator FAQ
How many bricks are in a square foot?
This calculator starts at 7 bricks per square foot as a planning input. Replace it with the density for the selected brick, joint, and pattern.
How do I calculate bricks for a wall?
Multiply net wall square footage by bricks per square foot, multiply by one plus the waste rate, and round up.
Should I subtract windows and doors?
Subtract large openings that materially reduce masonry area. Handle smaller openings consistently and avoid counting the same loss again through an inflated waste rate.
Does the result include mortar?
No. It counts field bricks only. Price mortar, accessories, delivery, labor, and equipment separately.
