Measuring the housing area is a necessary part of the renovation budget. The accuracy of the decoration area is to save money, save time and worry. No matter what material you buy, you can do it all at once. Not much, avoid unnecessary waste.

Tools: Ordinary tape measure, calculator. Note: Measure refers to measuring and calculating two different steps. Measurement: The main measure is the actual size of the house.
Step 1: Get a detailed standard floor or floor plan of your home.
According to the detailed residential floor plan measurement and calculation can be convenient and accurate. The main data that should be included in the floor plan are: the dimensions of each room's axis (ie, the dimension between the center lines of the load-bearing walls or columns) and the total size of the external walls, ie the two dimensions, and the area of ​​use of each room.
Most of the households are on the standard floor. Measurements and calculations are mainly based on standard floor plans and areas. If the floor of the residence is more special, such as the bottom floor, the drawing of the floor where the residence is located is used. In order to measure the area of ​​a house, it is not necessary to measure the area of ​​the entire building.
Step two:
Measure and calculate your own internal use area and floor area. Use area estimates. The size obtained by measuring the interior of the room is the size of the room axis minus the thickness of the wall and the thickness of the screed and cannot be used as the size in the area. In other words, the area calculated from this size is not the use area. The use area is calculated based on the internal dimensions of the room, which is the dimension of the axial dimension to remove the thickness of the structure. In general, when the load-bearing wall is a brick wall, the structure is 24 cm thick, the wall thickness in the cold area is 37 cm, the thickness of the concrete wall structure is 20 cm or 16 cm, and the non-bearing walls are 12 cm, 10 cm, and 8 cm. In general, the axis is located in the middle of the wall, and each side is half a wall thickness. White plaster thickness is generally 2-3cm.
The measurement position should be at a height of 1-1.2 meters above the ground. For rooms with an axis size of 360 cm, the measurement result should be 360-20-2.5 x 2 = 335 cm. Based on this, the dimensions of the room's internal axis can be calculated to be 360cm and the calculated size is 340cm. If the dimensional error is within a few centimeters, it means that the thickness of the plaster is inaccurate and uneven. Generally, it does not affect the size of the axis and the internal dimensions of the room.
There may be problems if the error is close to or exceeds 20 cm. Measure the interior dimensions of the room in both directions and multiply to get the room area. The area of ​​doors and windows is not included in the area of ​​use.
Each room (including: foyer, aisle, hall, bedroom, kitchen, bathroom, storage room, wallpaper, balcony and other non-fixed structure surrounded by space) use area for the total area of ​​residential use.
House floor area measurement
Separate the intersection of your home and other homes and public areas along the axis. The total area between your homes' axes is the total floor area of ​​your home. The calculation method is to add the total use area to the structural area of ​​each section of the wall; one is to directly calculate the area of ​​the geometry enclosed by its own axis. However, the total building area in a dwelling is generally not marked in the drawings and has no substantive meaning. It is only used for the next calculation of the total residential building area.
