Question 1

How many bricks per square foot?

Accepted Answer

With standard modular bricks (8 x 2-1/4 inches) and 3/8-inch mortar joints, you need approximately 6.5-7 bricks per square foot for a single-wythe wall. For pavers laid flat without mortar, about 4.5 bricks per square foot.

Question 2

What size is a standard brick?

Accepted Answer

The standard modular brick in the US is 7-5/8 x 3-5/8 x 2-1/4 inches (actual). With 3/8-inch mortar joints, it creates an 8 x 4 x 2-2/3 inch module. Other common sizes include queen, king, and utility bricks.

Question 3

How much mortar do I need?

Accepted Answer

Approximately 7 bags of 80-lb mortar mix per 1,000 standard bricks with 3/8-inch joints. For thicker joints or larger bricks, you will need more. One 80-lb bag of mortar mix yields about 30 standard-joint bricks.

Question 4

What is the waste factor for bricks?

Accepted Answer

Use 5% for simple straight walls with running bond pattern. Use 10% for walls with corners and openings. Use 15% for complex patterns like herringbone or basketweave, which require more cuts.
