How to calculate wall area for painting?

You cannot determine the cost of painting unless you first calculate the total area of the wall that you are planning to paint. I have never been good at math, so I had to do a bit of research on how to calculate area for painting. The formula is quite easy but you need to have the correct measurements. Since I am now aware of how to calculate wall painting area, I can help you understand it.

How to calculate square feet for painting walls?

To calculate the square feet for painting walls, at first:

• Measure the height and width of each wall you want to paint in the same unit (e.g., feet or metres).

• Then multiply the height by the width of each wall to find its area in square units.

• Add up the areas of all the walls you plan to paint.

• Deduct the area of doors and windows from the total wall area.

Example: If you have four walls, each 10 ft high and 12 ft wide, the total wall area is 480 sq. ft (4 walls x 10 ft x 12 ft). Deduct window and door areas to find the exact paintable area. I hope this paint area calculation formula will help you get your paintable area.

I was in urgent need to paint the walls of my bedroom. I wanted to do it myself. However, I was not very sure about the amount of paint that I should buy. I found the above-mentioned response on the NoBroker forum page. Manjot’s answer helped me with the painting area calculation.

Paint area calculation depends on whether you also want to paint the ceilings along with the walls.

• Ceilings:

Multiply the room's length by its breadth to determine the size of the floor area. For instance, 4 x 6 = 24 square metres if the room is 4 m wide and 6 m long. There will be a total of 2 coats needed, thus you will need sufficient paint to cover 48 square metres.

• Walls:

The area of room for painting formula will be the area of the ceiling + the area of the walls

Area of the ceiling is the same as the area of the floor. To evaluate the area of the floor, you need to determine the room’s length and the room’s breadth and multiply the two.

To calculate the total area of the walls, you will need to add the length of each wall and then multiply it by the height of the room,

For instance, if the room’s dimension is 10 feet x 10 feet, then the total floor area (plus ceiling area) is 100 square feet.

If the total wall area is 40 feet and the height is 10 feet, then the total wall area is 40x10= 400 square feet

Remember to take into account any windows or doors while measuring so that the amount of paint needed is reduced.

Don’t you love how a fresh coat of paint transforms our rooms? But painting is a house-improvement job that needs planning. This job will go more smoothly if you know how much paint you will require before you start painting. Read below to know how to calculate paint area as well as about paint calculator square feet:

• Measure the width and height of every wall of your room.

• Calculate the surface area of every wall in square feet or meters by multiplying the width and height.

• Add the totals of the 4 walls together to determine the total preliminary surface area of the walls

• Subtract the surface area of windows and doors including the frame, while determining how much paint you will require.

• Subtract the area of the windows and doors from four walls’ total surface area to calculate the net surface area.

• If you are planning to paint specific areas, such as window sills, the same colour as the walls, then you can add 10% to your net surface area.

• Calculate the ceiling’s surface area by measuring the length and width of the floor.

• Now, you will be able to calculate how much paint you will require to paint the room.

If you think this calculation is difficult, then you can take the help of a paint calculator (link given below) to calculate the paint area.

I hope now you know how to calculate wall area for painting as well as about paint calculator square feet.
