How to calculate the area of the painting
You will need
  • roulette;
  • notebook;
  • - handle;
  • calculator.
Instruction
1
To calculate the area of the coloring of the floor, multiply the length by the width. This will be the area of the painting. To calculate the amount of paint you need, read the instructions on the packaging from the manufacturer. There always has information about the amount of paint that is specified in square metres. These instructions correspond to the coating on a single layer. If you are going to paint a wooden surface, so that the charge is adequate, treat all painted surfaces with primer or varnish. Then, the specified flow will exactly match the actual flow. When painting the surface in two coats, multiply the calculated area of a floor or two.
2
To calculate the area of painting the ceiling, make exactly the same calculation as sex, that is multiply the length by the width. If the ceiling has any additional protrusions or niches, calculate their area separately and add to the total area of the painting, multiply the result by two if you want to produce color in two layers.
3
If you wish to clean the walls where there are Windows and doors, calculate the total areaby multiplying the length of each of the painted wall in the width, add the calculated numbers. Separately calculate area of doors and Windows by multiplying length by width, add up the digits and subtract the result from the total area of all the walls.
4
To paint the battery and the heating pipes calculate the area of the batteries. To do this, multiply the length by the width, add to the number of 20% if the batteries have a convex shape.
5
To calculate the area of painting of pipe, measure the entire length of the pipe, multiply by the diameter and multiply by two, as the pipes also need to paint on two layers.
6
To calculate the square painting the window frames, measure the length of the frames, add all the resulting numbers, and multiply by the width. Separately calculate area of window-sill, multiplying length by width. Add the obtained square to the square frames. This method calculate all the frames, put the obtained results.
Note
Buying paint, always read the area of the color indicated on the label. Paint from different manufacturers may have a different structure, and the area of coloring will vary.

Advice 2: How to calculate the area of the walls

For the first time, getting to the repair work, people often ask yourself the question - where to start? The first thing you need to calculate the quantity of materials necessary, and for this to determine what the surface will be repaired. The most important thing is possible to accurately determine the area of the walls, especially if you are going to cover them with tile. Tools which are usually used by professional finishers do not always have at hand the dilettante. But the area of the walls can be measured using any means available.
To determine the amount of materials you need to calculate the area of the walls
You will need
  • Roulette
  • Rake
  • Spirit level
  • A sheet of paper with a pencil or calculator
  • Of stool or ladder
Instruction
1
Put on the wall vertical and horizontal lines. Vertical line guide closer to the corner of the room. To verify the accuracy of the lines with a spirit level. The height of the walls in the room are usually the same, so start with her. Place the ladder closer to the corner of the room and attach zero roulette to the point of intersection of the vertical line of the ceiling. Roulette align with the line. Carefully go down from the ladder, holding the tape measure. View, a division of roulette was in the point of intersection of the vertical line with the floor or baseboard. Record the height.
2
Measure the length of the room. It's best to do on a horizontal line, parallel to the floor or baseboard if it is smooth. Zero mark will align with the corner of the room, lay the tape measure along the line and note the division, which is aligned with the second corner.
3
Similarly, measure and record the width. Find the perimeter of the room, arms folded along the length and width and multiplying the resulting sum by 2. Calculate the wall surface area by multiplying the perimeter of the room multiplied by the height.
Note
If you don't want to Wallpaper all the walls, find only the area needed. The length of wall and multiply by the height, and similarly guide calculation for all other walls.

If the room has a niche, compute separately the area of the walls of the niche and the area of the other walls.

Decide whether to glue the Wallpaper to the ceiling or leave a free stripe on top. Determine what will be the width of this strip and subtract its square from the square walls.
Useful advice
Before start measuring, please clean and align the wall.

The height measure together. Combines single zero roulette with the point of intersection of the vertical line and the ceiling, the other looking mark at the intersection with the floor or the baseboard.

If you do not have roulette, you can use a long cord. Tie a knot in it and align it with the point of intersection of angular lines and ceiling. Pull the cord and at the intersection of it with the floor tie the second knot. The distance between the knots can be measured with a regular ruler.

Advice 3: How to calculate the area of a room

Sooner or later there comes a time when you need to do repairs. They say that if you do repairs only in one room, then the number of carries dirt this process is similar to repair a flat.

Using a ruler measure the length and width of the room. Record the result in a notebook.
2
If your room lacks any protrusions or, on the contrary, holes in the walls, and shape of the room is a regular rectangle, to calculate area, multiply the resulting measurements to each other. This figure will be the total area of the room.
3
However, if your room is located, for example, part of a closet or in a room with some pillars, then you have to exclude these dimensions from the obtained measurement results. For this additionally calculate the area of each protruding element of the room and subtract it from the total area of the room.
4
Guided by the same principle, calculate the area of all room walls. To exclude the size of door openings and Windows, and also add an additional area of the walls arches such as under radiators. By doing thus, all the necessary measurements, you will get the exact area of the room, all its walls and floors and be able to calculate the amount of Wallpaper, linoleum or other materials you will need for repair.
