Indoor Area Formula? How to calculate the indoor area in square meters

Calculation of indoor area 1. Calculation of wall area. The decorative materials of the wall (including the column) generally include: paint, stone, wall tiles, wallpaper, soft packaging, and wainscoting.

When calculating the area, the calculation method is different depending on the material: apaint, wallpaper. The area of soft packaging and wainscoting is the length and height, and the unit is calculated in "square meters".

Length: calculated based on the net length of the main wall; Height: Calculated from the indoor ground to the bottom of the floor without wall skirting; If there is a wall skirt, it is counted from the apex of the wall skirt to the floor floor; If there is a suspended ceiling, it is calculated from the indoor ground (or the apex of the wall skirt) to the lower edge of the ceiling, and another 20 cm is added.

The area occupied by doors and windows should be deducted, but not the baseboard, the corner line, the area of the hole within the square meter and the area where the beam head and the wall are handed over. B, inlaid stone and wall tiles, according to the actual paving area in "square meters" calculation, the unit is meters. 2. Calculation of the top surface area.

The decoration materials of ceilings (including beams) generally include paints, suspended ceilings, corner lines (decorative corner flowers) and lighting ceilings. The area of the ceiling construction is calculated in "square meters" according to the net area between the walls, excluding the area occupied by the partition wall, columns, buttresses and nearby chimneys through the ceiling. The length of the top corner line is calculated in "meters" based on the net perimeter of the interior wall of the house.

3. Calculation of ground area. Flooring materials generally include: wooden flooring, floor tiles (or stone), carpets, stair treads and handrails, etc.

a. The ground area is calculated in "square meters" according to the net area between the walls, excluding the area occupied by the partition wall, columns, buttresses and nearby chimneys passing through the ground. b. The area of the stair tread is calculated in "square meters" according to the actual area, and the area occupied by the stairwell with a width of less than 30 cm is not deducted; The length of the stair handrails and railings (excluding the inside of the wall) factor is calculated in "extension meters". The length of other railings and handrails is calculated directly according to the "extension meter".

Calculation method of indoor space: length * width * height = room space.

Calculation method of indoor area: length * width = room area.

Example: A house 12 meters long, 4 meters wide, and 3 meters high.

The room space is: 12*4*3=144 cubic meters.

Room size: 12*4=48 square meters.

After the renovation of the new house, there is indoor air pollution, including formaldehyde and other gases that are harmful to the human body, it is recommended to open the window for 2-4 weeks, and put some flowers indoors, such as spider plant, tiger tail orchid, ivy, aloe vera, agave, Fulang flower, chrysanthemum, pothos, begonia, duck plant. Spider plant can absorb more than 80% of indoor harmful gases, and the ability to absorb formaldehyde is super strong.

Room size = length and width. The area of the room generally refers to the area inside a certain room, and the length and width of the room should be measured at a height of 1m from the ground, which will be more accurate. Because if the ground is uneven, it will affect the deviation of the measurement data.

First we need to measure the length and width of a room. Then add up the area of each small room to give the sum of the total area of a large room.

The area of an irregular house needs to be divided into rectangles of specifications, calculated separately and summed.

Generally speaking, the public area of multi-storey houses is small, and the public share of high-rise houses is large. Because high-rise houses will have elevators, shafts, elevators and other areas apportioned.

The calculation of the indoor area needs to follow the following rules and algorithms for limb age:1Determine the room range for the calculation:

First of all, it is necessary to determine the range of the room that needs to be calculated, which is generally the ground area that can be seen, including wall corners, door and window openings, etc. 2.Measure length and width:

Use measuring tools (e.g., tape measures, laser rangefinders, etc.) to measure the length and width of all corners in the room. It should be noted that the length of the corners should be from one corner to another, ignoring the length of the notch such as the opening of doors and windows. Similarly, the width of the corners should be from floor to ceiling height.

3.Calculate the area: Multiply the length and width of each room to get the area of the corresponding room.

If the shape of the room is a regular shape, you can calculate it directly using the corresponding formula, for example, the area of a rectangle is length multiplied by width. If the shape of the room is more complex, you can divide the room into several small areas to calculate, and add the areas of each small area to get the area of the whole room. 4.

Dealing with special circumstances: If there are uneven floors, columns, stairs and other special circumstances in the room, you need to adjust accordingly according to the actual situation. It should be noted that the calculation of indoor area is a relatively complex process that requires certain measurement skills and computing ability.

If you are unsure about your measurement and calculation capabilities, it is advisable to seek professional help and guidance before taking measurements.

<> indoor area is divided into two types: construction area and use area. The building surface is calculated from the axis of the wall and the depth, the usable area is to directly measure the distance between the wall and the wall, the height of the wall is multiplied by the perimeter of the ground area to obtain the area of the outer enclosure, the partition in the house needs to be multiplied by the height of the wall by the length of the song because of different designs, calculated by the longest place, and then subtract the area of the doors and windows.

<>The algorithm for indoor area is relatively simple and is equal to the length of the room multiplied by the width. The interior area does not have much to do with the height of the base sliding book. Height-related, generally the space area of the interior.

1. The formula for calculating the indoor area of the house is as follows:

2. Indoor construction area = usable area in the set + wall area in the set + balcony area.

4. Calculation of the area in the house suite:

5. The usable area in the suite refers to the actual usable area of the house, that is, it is also known as the carpet area; The area in the suite is generally Qi Dan refers to the construction area in the suite, which is the sum of the usable area in the suite and the apportioned area in the suite. The calculation of the usable area in the suite is mainly reflected in the following five aspects:

6. (1) The indoor usable area is calculated according to the inner surface size of the structural wall, and the wall has a composite thermal insulation and thermal insulation layer, which is calculated according to the size of the inner skin of the composite layer.

7. (2) Chimneys, Tongfeng roads, and various pipeline shafts are not included in the usable area.

8. (3) Non-public stairs (including the set of internal stairs in the duplex residence) shall be included in the area of the town according to the total usable area of the natural floors.

9. (4) The usable area of the residence includes bedrooms, living rooms (halls), kitchens, toilets, dining rooms, halls, corridors, front rooms, storage rooms, balconies, wall cabinets, etc.

10. (5) Usable area coefficient in the suite: When the area of the house is calculated according to the set (unit), the usable area coefficient is the ratio (%) of the usable area in the suite to the construction area in the suite plus the common construction area that should be apportioned according to the regulations

In the process of interior decoration, before purchasing decoration materials, we must make a corresponding understanding of each area of the interior, and then purchase a certain number of decoration materials according to the area, so how to calculate the indoor wall area? The first thing you need to understand is the formula for calculating the indoor wall area, so let's take a look!

1. Formula for calculating indoor wall area.

The length of the wall height The area of the windows and doors = the solid area of the wall.

2. How to calculate the indoor wall area.

1.Budgetary estimate. Wall Area Calculation:

The usable area of the ground 3. For example, if you want to budget the area of latex surge paint, you can subtract the floor area of the bathroom and kitchen from the floor area of the interior floor and multiply it by 3. That is to say, if the interior area of the house is 100 square meters, then the area that needs to be painted with wall latex paint is between 200 and 220.

Calculation of the area of wall tiles in the bathroom and kitchen: Floor area 4. Since the windows and doors in these two areas are relatively small, it is necessary to multiply the floor area by four when budgeting for wall tiles.

Window meters: subject to the specific measurement size of the indoor window.

2.Precise calculations.

Accurate calculations, as the name suggests, are the actual measurements of the interior with measuring tools.

Calculation of wall area: length of wall + width of wall 2 room height - area of door - area of window.

The calculation of the baseboard should be calculated according to the net perimeter, and if there are triangles and trapezoids and arcs in the interior, the calculation method of the triangle ground area is: the bottom edge is multiplied by the height, and then multiplied by two; The trapezoidal area is calculated as follows: the upper edge plus the size of the lower edge, multiplied by the height, and multiplied by two.

Summary: The above is the formula for the calculation of the indoor wall area shared for everyone, I believe that after reading the above sharing, the calculation of the indoor wall area also has a corresponding smile.
