Before home decoration, it is very important to accurately measure the area of each part of the room, because this means that you are accurate in purchasing materials and estimate the money that should be spent on decoration. Although many families currently contract the overall decoration to the construction design unit, if you know how to calculate the decoration area, you will not be cheated when checking out

the items involved in home decoration are roughly divided into walls, ceilings, floors, doors, windows, etc.

1 Calculate the wall area:

the decorative materials of the wall (including the column surface) generally include paint, stone, wall tiles, wallpaper, soft bags, wall panels, skirting lines, etc. When calculating the area, the material is different, and the calculation method is also different. The area of paint, wallpaper, upholstery and wallboard shall be calculated in square meters by multiplying the length by the height. The length is calculated according to the net length of the main wall; Height: if there is no dado, calculate from the indoor ground to the floor bottom; If there is a dado, calculate from the top of the dado to the bottom of the floor; If there is a ceiling, add 20cm from the indoor ground (or the top of the dado) to the lower edge of the ceiling. The area occupied by doors and windows shall be deducted, but not the area of kick line, hanging mirror line, hole area with a single area of less than 0.3 square meters and the area of the connection between beam head and wall surface. When inlaying stones and wall tiles on the wall, it is calculated in square meters according to the actual paved area, and the area of installing kick angle plates is calculated according to the net perimeter of the interior wall of the house, with the unit of meters

2. Calculate the top surface area:

the decorative materials of the ceiling (including beams) generally include paint, ceiling, top corner line (decorative corner flower) and daylighting ceiling. The area of ceiling construction is calculated in "square meters" according to the net area between walls, excluding the area occupied by partition walls, columns, piers passing through the ceiling and wall attached chimneys. The length of the top corner line is calculated in meters according to the net perimeter of the interior wall of the house

3. Calculate the floor area:

the decorative materials of the floor generally include wood floors, floor tiles or stones, carpets, stair treads and handrails. The ground area is calculated in square meters according to the net area between walls, excluding the area occupied by partition walls, columns, piers and wall attached chimneys passing through the ground. The area of stair treads is calculated in square meters according to the actual developed area, without deducting the area occupied by stairwells with a width of less than 30cm; The length of stair handrails and railings can be calculated by multiplying their total horizontal projection length (excluding the length in the wall) by a factor of 1.15 to extend the meter. The length of other railings and handrails is directly calculated by the extension meter

4. There is no fixed requirement for the calculation of the area of furniture. Generally, the customary practice in the quotation of each decoration company shall prevail, and the statistics are generally in the unit of extended meter, square meter or item

but it should be noted that the unit of measurement of each kind of furniture should be consistent. For example, when making two wardrobes, there should be no phenomenon that one takes square meters as the unit of measurement and the other takes "items" as the unit of measurement
