Brick Calculator
Net wall area is length times height minus openings. Divide by brick length times brick height. Waste percent rounds the buy count up. Use the same unit for the wall and the brick face. Estimate only, not a bond schedule.

How to estimate a brick count
- Enter wall length and height in one unit. The default 20 by 8 uses the same unit as the brick face.
- Enter brick length and brick height in that same unit. Modular 8 by 2.25 only works if the wall is also in inches.
- Enter waste from 0 to 40 percent and optional opening area to subtract.
- Read net area, bricks before waste, and bricks to buy. Confirm with a mason. Estimate only.
Face-bedded brick count
Wall area divided by brick face, plus waste
| Net wall | max(0, length × height - openings) |
|---|---|
| Brick face | brick length × brick height |
| Raw count | net wall / brick face |
| Buy | ceil(raw × (1 + waste/100)) |
| Waste cap | 0 to 40 percent |
| Advice | Estimate only. Bond, mortar joint, and code are not a mason takeoff. |
What this brick count includes
The page treats each brick as a rectangle on the wall face. It does not add a mortar joint to the brick size, so you should type the modular size with joint if that is how you buy. Openings subtract area, not a window schedule. Tile on a floor is the tile calculator. Wall area without a unit count is square footage.
How bricks to buy are computed
net = max(0, wall length × wall height - openings). face = brickLength × brickHeight. raw = net / face. buy = ceil(raw × (1 + waste/100)). Waste stays from 0 to 40. All lengths share one unit. Mixing feet for the wall and inches for the brick produces a nonsense count.
Bond, joints, and openings
Running bond, stack bond, and soldier courses change cuts. Header courses use the brick length as the wall thickness, which this face-bedded model ignores. Fire-rated assemblies and veneer ties are code items, not this form.
Use cases
A veneer sketch, a homework area divided by 8 by 2.25, or adding 10% waste before you call a yard. Not structural masonry design.
Limits
No joint thickness field. No corners. Waste max 40%. Estimate only, not code approval. CZNull does not receive the sizes.
