How to calculate the expanded area of the cabinet
In the process of furniture customization or decoration, calculating the expansion area of the cabinet is an important step. The expansion area is not only related to the amount of material used, but also directly affects the cost and quotation. This article will introduce in detail the calculation method of the cabinet expansion area, and combine it with the hot topics and hot content on the Internet in the past 10 days to provide you with a practical reference.
1. What is the expansion area of the cabinet?

The expanded area of the cabinet refers to the total area after unfolding all the panels of the cabinet (including door panels, side panels, bottom panels, top panels, etc.). This concept is often used in quoting and material calculations for custom furniture.
2. Calculation method of cabinet expansion area
Calculating the expanded area of a cabinet requires adding the areas of each panel. The following are the specific calculation steps:
| Board type | Calculation formula | Example |
|---|---|---|
| Side panels | Height × Depth × 2 | Height 2000mm × Depth 600mm × 2 = 2.4㎡ |
| Top and bottom plates | Width × Depth × 2 | Width 1000mm × Depth 600mm × 2 = 1.2㎡ |
| door panel | Height × width × number of door panels | Height 2000mm × Width 500mm × 2 = 2.0㎡ |
| Partition | Width × Depth × Number of Partitions | Width 1000mm × Depth 600mm × 3 = 1.8㎡ |
| backplane | height × width | Height 2000mm × Width 1000mm = 2.0㎡ |
According to the above example, the total expansion area of the cabinet is: 2.4㎡ + 1.2㎡ + 2.0㎡ + 1.8㎡ + 2.0㎡ =9.4㎡.
3. The relationship between hot topics on the Internet in the past 10 days and the cabinet expansion area

| hot topics | Relevance | Description |

2.Loss rate: There will be a certain amount of material loss in actual production, usually between 5% and 10%, which needs to be considered in the quotation.
3.Hardware accessories: The calculation of expanded area usually does not include hardware accessories (such as hinges, slide rails, etc.), but these will also affect the total cost.
5. Summary

Accurate calculations can not only avoid quotation traps, but also help you plan materials and costs reasonably.
