The unit of measurement in brickwork is the 1000 bricks, ordinarily.

To determine the number of bricks in a wall, multiply each square foot of surface by 7 (sometimes 7½ is used) which is the average number of bricks per foot of wall when 4" thick. Add 5% for breakage. Deduct for openings over 2' square. For walls thicker than 4", make suitable allowance.

A mason can lay 800 to 1000 common and 300 to 400 face bricks in a day.

Bricks may be laid in lime mortar or in cement mortar.
