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

What is a modular brick?+

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.

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.
