1. Considering the size of the brick all are 9 inches we can calculate how much bricks required in one sq ft. I will provide you with the measurements below.

The given measurement for how many bricks required for 1 square feet :

As per the Indian standard size, the measurement of one brick is 9"x4.5"x3"

Brick wall's area= 1sq.ft

Cement mortar's thickness= 0.5"

The Brick wall's thickness= 9"

Calculation of the brick per sq. ft

• Firstly, we must include the thickness of the mortar in the Indian brick size.
• We need to calculate the volume of one brick including the mortar.
• Then we should measure the volume of the brick wall.
• Then we must add up the number of bricks by dividing the wall volume by the volume of one brick including the mortar.
• The total number of bricks for 1 sq. ft:

1.

Size of a brick including mortar

9″×4.5″×3″ brick size

=(9″+0.5″)×(4.5″+0.5″)×(3″+0.5″)

9.5″×5″×3.5″ brick size including mortar.

2.

The volume of a brick including mortar:

9.5″×5″×3.5″ =166.25 cubic inch

3.

Brick wall's volume:

Area × brick wall's thickness

=1 sq.ft ×9″ (1sq.ft =144 square inch)

= 144″×9″ =1296 cubic inch

4.

Amount of bricks= Brick wall's volume/ one brick wall's volume including mortar

Amount of bricks= 1296/166.25 =7.8 nos

If we consider 10% bricks to be wasted then the number becomes 0.78

We can calculate the total number of bricks if we add 7.8+ 0.78= 8.58.

If we round the number the total number of bricks becomes 9.

Therefore 9 bricks are required for 1 sq. ft.

2. Hey,
Thank you to … who has explained how many bricks in 1 square feet in concise terms. I would like to share another approach to the question in my comment. Not to say that ….’s answer is wrong by any means. When you know the exact number of bricks needed, then you will be able to cut corners and budget for the construction of your house.

#### How many bricks per sq ft?

To know the exact number of bricks needed, you will need to know the coverage area of 1 brick.

The coverage area of 1 brick is 0.222 sq ft or 32 square inches.

Eg. if you have to know the coverage area for 1000 bricks in square footage. Then the coverage area of 1000 bricks in square footage = 0.222 × 1000= 222 sq ft.

This will mean that 100 bricks will cover 222 square footage.

#### How many bricks in a square foot?

Before I share the exact number with you, let me preface this by saying that a brick wall is made of three types and sizes of bricks, those are four inches, 9 inches, and 13 inches.

If you use the standard ( 7.5" x 3.5" ) type of brick then 5 bricks will be needed per square foot.

You will also need 5 bricks per square foot if you use 9.5" x 2.75" bricks.

I have come to this number by the following process.

• The first step is taking the area of 1 brick.
• The area of a brick can be calculated by measuring the length and width of a given brick dimension and multiplying the length and width.
• I have then concerted square foot into square inch, 1 foot = 12 inch, then 1 sq ft = 12 × 12 = 144 square inch.
• Remember that a modular brick has a dimension length width and depth is 8″ × 4″ × 4″, in which length is 8″, the width of a brick is 4″, and the depth of the brick is 4″. All the non-modular bricks size in the market is is 9″ × 4.5″ × 3″ with which length is 9″, width is 4.5″ and depth is 3″.
• I have then divided 144 square inches by area of 1 brick 32 sq inches,

This is how I know the number of bricks in one sq ft = 144/32 = 4.5 or 5 bricks.

I hope your question on how many bricks in 1 square feet has been cleared. This is third This is third This is fourth This is fourth This is fifth This is fifth This is six This is six This is seven This is seven This is eight This is eight
