How Many Bricks Required For 100 Square Feet Room (4 Inch Wall)
To calculate the number of bricks required for 100 square feet room, we have some requirements and considerations in the room.
Requirements
The common requirements for 100 square feet room are given following:- Four sided walls in room
- Minimum one door and
- One window in the room
Here, we are ignoring ventilator because most of room do not required.
Consideration
The considerations to calculate number of bricks in 100 square feet room are following:
- Size of room is 10 feet length and 10 feet width = 100 square feet
- Four sided wall (wall size = 10 feet height x 10 feet width or 120 inch height x 120 inch width).
- One window (window size = 4 feet x 3 feet or 48 inch x 36 inch).
- One gate ( gate size = 7 feet x 3 feet or 84 inch x 36 inch).
- Brick size (Indian standard modular brick size) = 190×90×90 mm or 7.48×3.54×3.54 inch
- Mortar thickness 12 mm and
- Wall thickness is 4 inch (Single brick thickness).
Calculate the Total Area of Walls For 100 Square Feet Room
To calculate number of bricks required for 100 square feet room, we need to calculate the area of each wall separately because there are four walls in the room. The total area of all four walls would be the sum of the areas of each wall.
- Length of the room = 10 feet
- Width of the room = 10 feet
- Height of the wall = 10 feet
Total Area of Wall Calculation
- Wall 1: Length × Height = 10 feet × 10 feet = 100 square feet
- Wall 2: Length × Height = 10 feet × 10 feet = 100 square feet
- Wall 3: Width × Height = 10 feet × 10 feet = 100 square feet
- Wall 4: Width × Height = 10 feet × 10 feet = 100 square feet
The Total Area of All Four Walls
Total area of walls in 100 square feet room
= Area of Wall 1 + Wall 2 + Wall 3 + Wall 4
= 100 + 100 + 100 + 100
= 400 Square Feet
Calculate Area of Openings (Door and Window)
Since there are one gate in the room and one window in the room.
- Height of the gate in 100 square feet room= 7 feet
- Width of the gate in 100 square feet room= 3 feet
- Height of the window in 100 square feet room= 4 feet
- Width of the window in 100 square feet room= 3 feet
Total Area of Door and Window
= Area of door + Area of Window
= (Height of door × Width of door) + (Height of window × Width of window)
= (7 feet × 3 feet) + (4 feet × 3 feet)
= 21 square feet + 12 square feet
= 33 square feet
Net Area of Walls in the Room
Net area of walls in the room
= Total area of walls - Total area of openings (door and window)
= 400 square feet - 33 square feet
= 367 square feet
Covering Area of a Brick With Mortar Thickness in 4 Inch Wall
Covering area of a brick with mortar in 4 Inch wall
= (Length of brick + Thickness of mortar layer) × (Height of brick + Thickness of mortar layer)
= (190 mm + 12 mm) × (90 mm + 12 mm)
= 202 mm × 102 mm
= 20604 mm²
= 0.222 square feet
Total Bricks Required For 100 Square Feet Room
Total bricks required for 100 square feet room
= Net area of walls in square feet / Covering area of a single brick
= 367 square feet / 0.222 square feet
= 1653 nos bricks.
Wastage Factor
Taking 10% extra as wastage of bricks during masonry work;
So that, total bricks required for 100 square feet room with 4 inch wall
= 1653+10% of 1653
= 1818 Nos Bricks
Final Result
The total number of bricks required for 100 square feet room of 4 inch wall thickness is approximately 1818 nos with one gate and one window.
So, we would need approximately 1818 bricks to construct a 100 square feet room with four walls of 10 feet height, 10 feet length, 10 feet width, one gate of 7 feet × 3 feet and one window of 4 feet × 3 feet by using standard brick size of 190×90×90 mm.
Note: This calculation is an estimate and may vary depending on factors such as the pattern of the brickwork, the size of the mortar joints and the amount of waste generated during construction. It is always a good idea to order a few extra bricks than what you think you will need in the construction.
In this we have not considered brickwork under the plinth level and ground level. If you need to construct under the ground level brick work, you should buy extra bricks.
How Many Bricks Required For 100 Square Feet Room (9 Inch Wall)
Total 3637 brick of Indian standard size is required for 100 square feet 9 inch wall. To calculate the number of bricks required for 100 square feet room with 9 inch wall, we have some requirements and considerations in the room.
Requirements
The common requirements for 100 square feet room are given following:- Four sided walls in room
- Minimum one door and
- One window in the room
Here, we are ignoring ventilator because most of room do not required.

The considerations to calculate number of bricks in 100 square feet room are following:
- Size of room is 10 feet length and 10 feet width = 100 square feet
- Four sided wall (wall size = 10 feet height x 10 feet width or 120 inch height x 120 inch width).
- One window (window size = 4 feet x 3 feet or 48 inch x 36 inch).
- One gate ( gate size = 7 feet x 3 feet or 84 inch x 36 inch).
- Brick size (Indian standard modular brick size) = 190×90×90 mm or 7.48×3.54×3.54 inch
- Mortar thickness 12 mm and
- Wall thickness is 9 inch (Double brick thickness).
Calculate the Total Area of Walls For 100 Square Feet Room
To calculate number of bricks required for 100 square feet room, we need to calculate the area of each wall separately because there are four walls in the room. The total area of all four walls would be the sum of the areas of each wall.
- Length of the room = 10 feet
- Width of the room = 10 feet
- Height of the wall = 10 feet
Total Area of Wall Calculation
- Wall 1: Length × Height = 10 feet × 10 feet = 100 square feet
- Wall 2: Length × Height = 10 feet × 10 feet = 100 square feet
- Wall 3: Width × Height = 10 feet × 10 feet = 100 square feet
- Wall 4: Width × Height = 10 feet × 10 feet = 100 square feet
The Total Area of All Four Walls
Total area of walls in 100 square feet room
= Area of Wall 1 + Wall 2 + Wall 3 + Wall 4
= 100 + 100 + 100 + 100
= 400 Square Feet
Calculate Area of Openings (Door and Window)
Since there are one gate in the room and one window in the room.
- Height of the gate in 100 square feet room= 7 feet
- Width of the gate in 100 square feet room= 3 feet
- Height of the window in 100 square feet room= 4 feet
- Width of the window in 100 square feet room= 3 feet
Total Area of Door and Window
= Area of door + Area of Window
= (Height of door × Width of door) + (Height of window × Width of window)
= (7 feet × 3 feet) + (4 feet × 3 feet)
= 21 square feet + 12 square feet
= 33 square feet
Net Area of Walls in the Room
Net area of walls in the room
= Total area of walls - Total area of openings (door and window)
= 400 square feet - 33 square feet
= 367 square feet
Since, we are using double brick thickness of wall. So, we need tho multiply net area of wall with 2.
Net area of double brick thickness wall
= 2×367 square feet
= 734 square feet
Covering Area of a Brick With Mortar Thickness in 4 Inch Wall
Covering area of a brick with mortar in 4 Inch wall
= (Length of brick + Thickness of mortar layer) × (Height of brick + Thickness of mortar layer)
= (190 mm + 12 mm) × (90 mm + 12 mm)
= 202 mm × 102 mm
= 20604 mm²
= 0.222 square feet
Total Bricks Required For 100 Square Feet Room
Total bricks required for 100 square feet room
= Net area of walls in square feet / Covering area of a single brick
= 734 square feet / 0.222 square feet
= 3306 nos bricks.
Wastage Factor
Taking 10% extra as wastage of bricks during masonry work;
So that, total bricks required for 100 square feet room with 9 inch wall
= 3306 +10% of 3306
= 3637 Nos Bricks
Final Result
The total number of bricks required for 100 square feet room of 9 inch wall thickness is approximately 3637 nos with one gate and one window.
So, we would need approximately 3637 bricks to construct a 100 square feet room with four walls of 10 feet height, 10 feet length, 10 feet width, one gate of 7 feet × 3 feet and one window of 4 feet × 3 feet by using standard brick size of 190×90×90 mm.
