How to calculate the area for decoration
During the renovation process, accurate calculation of the house area is the basis for budget planning and material procurement. Whether it's walls, floors or ceilings, precise measurements are needed to avoid waste or shortfalls. The following is a detailed analysis of common area calculation methods in decoration.
1. Calculation method of wall area
Calculation of wall area usually requires deducting doors and windows. The following is the specific formula:
| area | Calculation formula |
|---|---|
| single wall | Length × Height - Door and window area |
| multiple walls | The sum of the wall areas |
For example, if a wall is 5 meters long, 2.8 meters high, and has a 1.5×1.2 meter window, the wall area is: 5×2.8 - (1.5×1.2) = 14 - 1.8 = 12.2 square meters.
2. Ground area calculation method
The floor area is generally calculated based on the net size of the room, without deducting fixed furniture such as cabinets:
| shape | Calculation formula |
|---|---|
| Rectangle | length × width |
| irregular shape | Divide into multiple rectangles and calculate separately and then sum |
3. Ceiling area calculation method
The ceiling area is usually equal to the floor area, but special treatment for the suspended ceiling should be noted:
| Type | Calculation method |
|---|---|
| flat ceiling | Same floor area |
| Styling ceiling | Calculated based on expanded area |

5. Special precautions
1.Loss calculation: Ceramic tiles and other materials need to increase the loss by 5-10%
2.unit of measurement: Materials such as paint may be priced by "barrel" rather than by area
3.Retest timing: After the disassembly and modification are completed, the actual size needs to be measured again.
Mastering the correct area calculation method can not only prevent decoration companies from falsely reporting the area, but also accurately control material costs. It is recommended that the owner measure the basic data by himself and then check with the construction party for confirmation.
