To calculate the number of bricks in a 4″ and 9″ wall, you need to consider both the length and height of the wall.

1. Measure the wall length: Measure the length of the wall in inches.

2. Measure the wall height: Measure the height of the wall in inches.

3. Convert measurements to feet: Convert the measurements to feet if they are not already in that unit. There are 12 inches in a foot.

4. Calculate the area of one brick: Determine the dimensions of a standard brick (length, width, and height) and calculate its area.

5. Calculate the wall area: Multiply the length and height of the wall to get the total wall area.

6. Divide by the brick area: Divide the total wall area by the area of one brick to find the number of bricks needed.

Remember to account for mortar joints, and consider buying a few extra bricks for any potential wastage or breakage during construction.

When you are think about starting and new projects of brick structure as external and internal partition wall in the house, boundaries for Garden, retaining wall, brick pier, etc, one of the toughest aspect is determining how many bricks you will need, ordering few bricks make delay in construction for over ordering make loss of money that increases your estimate for construction.

In this article you will calculate number of bricks in a wall by using Thumb Rule based on experience and calculation. I will explain How to calculate bricks in a wall.

There are two types of brick wall, one is full (one) brick wall have thickness with mortar is 200mm and other is half- brick wall have thickness is 100mm, in india, standard size of brick is 190mm × 90mm × 90mm, in which length is 190mm, breadth is 90mm & thickness is 90mm, thickness of mortar is 10mm, add 10mm mortar in each dimensions of brick, so nominal size of brick is 200mm × 100mm × 100mm.

**How to calculate bricks in a wall**

There are two types of brick wall, full brick wall and half brick wall, if you want to calculate bricks in a wall and to determine how many bricks you will need, follows in easy steps:-

**How to calculate bricks in a wall:-**

**For half brick – thick wall**

1) Using thumb rule, half brick wall or singular layer or 4″ brick wall, multiply the length of wall by the height to get area measured in square meter. Multiply that area by 50 to get the number of bricks you should need, then add @10% extra for wastage and breakage during transportation storage and brick wall installation.

2) half brick thick wall = 50 bricks per square meter + extra 10%

3) number of bricks for half brick wall = Area of wall in sqm × 50 + extra @10%.

4) consider a half brick wall of length 12.5 m and height is 4m, area = 12.5× 4 = 50 sqm, number of bricks = (50 × 50) + 10% of (50 × 50) = 2750 nos, so there are 2750 nos bricks you will need for 50 square meter of half brick – thick wall.

**For one brick – thick wall**

1) Using thumb rule, one brick thick wall or double layer or 9″ brick wall, multiply the length of wall by the height to get area measured in square meter. Multiply that area by 100 to get the number of bricks you should need, then add @10% extra for wastage and breakage during transportation, storage and brick wall installation.

2) One brick thick wall = 100 bricks per square meter + extra @10%

3) number of bricks for one brick – thick wall = Area of wall in sqm × 100 + extra @10%

4) consider one brick – thick wall of length 12.5 m and height is 4m, area = 12.5× 4 = 50 sqm, number of bricks = (50 × 100) + 10% of (50 × 100) = 5500 nos, so there are 5500 nos bricks you will need for 50 square meter of one brick – thick wall.

**How to calculate bricks per square feet**

In india, standard size of brick is 190mm × 90mm × 90mm (length is 190mm, breadth is 90mm & thickness is 90mm), add 10mm mortar in each dimensions to get nominal size as 200mm × 100mm × 100mm or 8″ × 4″ × 4″.

Consider one brick – thick wall of length 10 feet in length and height is 10 feet, area = 10× 10 = 100 square footage, thickness of double brick wall is 8 inch, so volume of wall = 100 sq ft × 8/12 = 66.66 cubic feet.

Volume of one bricks = 8″ × 4″ × 4″ = 0.66′ × 0.33′ × 0.33′ = 0.0718 cubic feet.

Number of bricks in a wall = volume of wall/ volume of one brick with mortar, as 66.66/ 0.0718 = 927 nos.

You will need extra 10% damage and breakage during transportation, storage and brick wall installation, so 10% of 927 = 93 bricks, add extra 93 bricks, 927 + 93 = 1020, rounding it nearly equal to 1000 bricks.

**How to calculate bricks per square feet**:- 100 sq ft of double layer brick wall, you will need about 1000 brick, number of bricks per square feet for one brick – thick wall = 1000/ 100 = 10 nos, number of bricks per square feet for half brick – thick wall = 10/2 = 5 nos, so there are 10 bricks required for one brick – thick wall per square feet and for half brick – thick wall, there are 5 bricks per square feet, you needed.
