Calculating Brick and Tables for Estimating Brick Quantity

In this construction article briefly explain how to calculating brick and tables for estimating brick quantity.

a. Face area (in inches²) = Length of the brick x Height of the brick

b. Number of bricks you will require per square feet = 144 square inches/Height x Length of brick

c. Compute the area of space for inserting brick – Make sure to deduct space for openings (windows, doors, etc).

d. Brick Quantity = Area x number of bricks needed per square feet (Brick Multiplier) 

e. Add 5 to 10 % waste according to all-inclusive size of the job.

Mortar Required for Standard Size Brick:

a. Choose the joint thickness.

b. Choose the thickness of the wall.

c. Find the multiplier that matches step 1 and 2.

d. Divide the total number of bricks you are using by 1000. 

e. Take the multiplier and multiply it with the number calculated in step 4.

f. That will offer you CF of mortar required.

Illustration – CF of mortar required to install 8000 bricks. Joint thickness is 1/8’’ and thickness of the wall is 8’’.

a. Step 1 – 8000/1000 = 8

b. Step 2 – 8 x 5.6 = 44.8 CF of mortar

Discover the Size of your Mortar Joint:

a. Locate the number as per your brick size.

b. Multiply the number by the area for which you will be installing the brick.

c. The outcome will be the number of bricks you will need.

Illustration – Compute the amount of brick to be installed on 5000 square feet. You are using a jumbo brick with ¼’’ joint. The result will be 5000 x 1.16 = 5800 bricks.
