How thick should the mortar joint be?

⅜" (0.375 in) is standard for most exterior masonry. Some restoration work uses ¼" or ½" depending on the original joint.

Does this account for openings (doors and windows)?

Not directly — enter the wall area minus openings yourself if accuracy matters. For rough estimates, the waste factor often absorbs reasonable opening losses.

How many courses tall is an 8 ft wall?

About 32 courses with modular brick at 2.25" face + ⅜" joint = 2⅝" per course.

Should I always order extras?

Yes — at least 5-10% to cover breakage. Try to order from the same kiln batch for color consistency on visible walls.

Result

Bricks needed

1207 bricks

160 ft² of wall, 10% waste included.

Bricks per row30.0
Courses (vertical rows)36.6
Wall area160.0 ft²

Step-by-step

Per-row count: wall length / (brick L + joint) = 240.0 ÷ (7.625 + 0.375) = 30.00.
Courses: wall height / (brick H + joint) = 96.0 ÷ (2.25 + 0.375) = 36.57.
Total: 30.0 × 36.6 × (1 + 0.10) ≈ 1207.

How to use this calculator

Enter wall length and height in feet.
Pick the brick size — modular is the default.
Adjust joint and waste if your masons run different specs.

About this calculator

Brick count for a wall is just wall area divided by the area of one brick (face dimension + mortar joint), with a waste factor. Modular bricks are by far the most common size in residential construction; queen and utility bricks are larger and reduce the count for big jobs.

Frequently asked

A modular brick is sized so that 3 bricks plus 3 joints stack to exactly 8 inches vertically — making layout math clean. It is the dominant residential size.
