How do I measure the area of walls of a room in sq. ft?

Answer 1

Measure the length of each wall. Add up the numbers, measure the height (typically 8 feet). Multiply the total length by the height. Measure any openings (doors & windows) using the same method (L x H), and subtract that from the total. The result will be the surface area of your walls in sq. ft.

Answer 2

Basically, it is height times width. Of course, you should deduct for doors and windows. Rather than try to divide the room into little sections around the doors and windows, look at the wall as one big rectangle without the doors and windows, multiply that, then measure the windows and door, multiply them,add up those sums and deduct that total from the rectangle you first measured.
Since ceiling heights throughout the house are usually the same, you can use that measurement as a default, then you only have to measure horizontally.
An example; A standard 30" door would measure, including 2 1/2" casings, 35" x 83" = 2905 square inches. There are 144 square inches in a square foot. So, to find the square feet, divide 144 into 2905. Answer is 20.17 sq. ft. or, 20 square feet.

Answer 3

To measure the area of any flat surface you multiply the length by the width.
To find the area of walls you can measure the length of the perimeter of the walls, that is the total length of all the walls and multiply that number by the height of the wall.
Example:
The room is 12' 6" by 10' 3" wide and 8' high.
The perimeter then is; 12' 6" + 12' 6" + 10' 3" + 10' 3" or 45' 6"
45' 6" X 8 + 364 square Feet of wall area.

Answer 4

For walls, you have to measure the height of the wall and the length of the wall. Take those measurements in feet and multiply the two measurements (height X length). You might have to round up. It depends what you need the sq. footage for.

Answer 5

multiply width x height and say 8 foot height and 20 foot long the wall is 160 square feet. a 12 x 12 room at 8 ft would be 96 square foot per wall x 4 walls youde have 384 and so ... on and so... on and in reading others answers do not deduct for windows or doors cause it make you short of material whether its a paer or paneling or sheetrock your putting up you will be short and not able to follow a pattern and sheetrocks thesame you want a factory end to butt

Answer 6

Measure length x's height for square footage, if you have a lot of windows measure them the same way then subtract that total of the windows from the intial wall measurement!

Answer 7

Measure the perimeter of the room then times it be the height, that will give you square feet, but don't forget to deduct the areas of the doors and windows

Answer 8

Measure the hight times the width. for each wall. In other words from the floor to the ceiling and from one end of the wall to the other. do this for each wall in the room to get you total wall square footage. Hight ( 8ft. ) x Width ( 10ft. ) = Area ( 80sq.ft. )

Answer 9

hello!
here's your answer...

To calculate the square footage of the walls, measure the length (L) multiplied by the height (H) of the wall. This will give you the square footage needed to cover the area....

any other questions, let me know..

Answer 10

length x width= sq ft. for ex; 10x12 ft wall would be 120sq ft
