How to calculate the expansion area of the cabinet
In the process of furniture customization or decoration, calculating the expansion area of the cabinet is a common but easily overlooked detail. The expansion area is not only related to the material cost, but also directly affects the quotation and construction plan. This article will give you a detailed analysis of the calculation method of the cabinet expansion area, and provide structured data for easy reference.
1. What is the expansion area of the cabinet?
The expanded area refers to the total area of the cabinet after dismantling all the panels (including side panels, partitions, back panels, etc.). Unlike projected area (only the front view area is calculated), expanded area more accurately reflects the actual amount of material used.
2. Key steps in calculating the expanded area
1.Split cabinet structure: Decompose the cabinet into independent panels (such as top panel, bottom panel, side panel, etc.).
2.Measure the dimensions of individual panels: Record the length, width and thickness of each board (the units are recommended to be unified in millimeters).
3.Calculate the area of a single block: Length × width, please note that the reused plates need to be accumulated.
4.Total total area: Add the areas of all panels.
3. Examples of calculating the expansion area of common cabinet types
| Cabinet type | Quantity of plates | Single block size (mm) | Total area (㎡) |
|---|---|---|---|
| single door wardrobe | 6 yuan | 1200×600×18 | 4.32 |
| Bookcase (3 layers) | 5 yuan | 800×300×15 | 1.20 |
| Cabinets (base cabinets) | 8 yuan | 700×500×18 | 2.80 |
4. Factors affecting the expansion area
1.Cabinet structural complexity: The more drawers and compartments there are, the greater the amount of board used.
2.Material thickness: Usually 18mm thick plate is standard, but 9mm may be used for the back plate.
3.special design: Curved, chamfered and other special-shaped plates need to be calculated separately.
5. Practical suggestions for cost saving
1. Prioritize standard size plates to reduce cutting waste.
2. Plan the internal structure reasonably to avoid excessive separation.
3. Compare the calculation methods of different merchants (some will deduct the hinge hole area).

7. Summary
Mastering the calculation method of cabinet expansion area can effectively avoid hidden consumption during the decoration process. It is recommended that before signing a contract, the owner requires the merchant to provide a detailed split sheet and review the key data by himself. If precise calculation is required, CAD software or professional order disassembly tools can be used to assist.
