If you are going to plaster walls, glue wallpaper, or tiles, you need to calculate the amount of material needed for repair. Having calculated the area of uXNUMXbuXNUMXbthe walls, you need to subtract from them the dimensions of the doorway and window. This will help you not to overpay for materials for repairs. A calculator will help you accurately calculate the area of uXNUMXbuXNUMXbthe door.
To calculate the area of the door, you need to multiply its height by the width. A tape measure is used for measurements, and the data obtained is used in centimeters or converted to meters.
The formula for calculating the door area for dimensions in meters:
S=h*a
For calculations in centimeters:
S=h*а/10000
Where:
- S – door area;
- b – width;
- h – height.
As a result, we find out the area of uXNUMXbuXNUMXbthe door or opening in square meters – м2.
The online calculator will do the calculations for you quickly and without errors. It is necessary to measure in centimeters to the outer part of the door frame or extensions.
If in the calculator along with the doorway we enter the dimensions of the window, we will get their total area. When repairing a room, this size must be subtracted from the total area of uXNUMXbuXNUMXbthe walls so as not to purchase excess material. To calculate, measure the frame of a window or window opening in centimeters, and enter it in the fields of the second opening of the calculator.
