How to calculate the expanded area of the cabinet? An article explaining the calculation methods and precautions in detail
When customizing cabinets, the calculation of the expanded area is directly related to the amount of material and the final quotation. Many consumers are confused about how to accurately calculate the cabinet expansion area. This article will introduce you to the calculation method in detail and attach a structured data table to help you easily master this key knowledge point.
1. What is the expansion area of the cabinet?
The expanded area refers to the total area after all the cabinet panels (including door panels, side panels, bottom panels, back panels, etc.) are expanded and tiled. This calculation method is more accurate than the projected area and can truly reflect the amount of material used.
| Calculation method | Features | Applicable scenarios |
|---|---|---|
| Expanded area | Calculated based on actual plate area used | Customized cabinets, accurate quotation |
| Projected area | Calculated based on front projection size | Finished cabinets, quick quotation |
2. Calculation formula for cabinet expansion area
Basic formula: expanded area = ∑ (length of each plate × width)
| components | Calculation formula | Example |
|---|---|---|
| Cabinet panels | (Height×Depth)×2 + (Width×Depth)×2 + (Width×Height) | 600mm high × 500mm deep × 800mm wide cabinet: (0.6×0.5)×2 + (0.8×0.5)×2 + (0.8×0.6)=2.68㎡ |
| door panel | width×height | 800mm×600mm door panel=0.48㎡ |
| Partition | Width×Depth | 780mm×450mm partition=0.351㎡ |
3. Detailed explanation of calculation steps
1.Measure cabinet dimensions: Accurately measure the length, width, height and depth of each cabinet (unit: mm)
2.Itemized calculation: Decompose the cabinet into individual plates and calculate them separately.
3.cumulative sum: Add the areas of all plates to get the total expanded area
4.increase loss: Usually need to add 5-10% material loss
| Cabinet type | Expanded area coefficient | illustrate |
|---|---|---|
| Base cabinet | 3.5-4.5 times the projected area | Including drawers, pull baskets, etc. |
| wall cabinet | 2.5-3.5 times the projected area | Simpler than floor cabinet |
| High cabinet | 4.0-5.5 times projection area | Contains internal structure |
4. Precautions
1.Hardware is not included: Hardware such as hinges and slide rails are not included in the area calculation.
2.Special structure processing: Curved and special-shaped cabinets need to be calculated separately
3.Door panel calculation: Usually door panel area = opening size + 3mm surrounding gap
4.Back plate thickness: The back panel is usually thin (5-9mm) and should be calculated separately from the side panels.
5. Frequently Asked Questions
Q: Why is the expanded area much larger than the projected area?
A: Because the expanded area is calculated for all visible and invisible panels, including internal partitions, back panels, etc.
Q: How to calculate the unfolded area of a corner cabinet?
A: The corner cabinet needs to be split into two or more standard cabinets and calculated separately.
Q: What is the average price per square meter of cabinet expansion area?
A: Depending on the material, the price varies greatly:
- Particle board: 200-400 yuan/㎡
- Multi-layer solid wood: 400-700 yuan/㎡
-Solid wood: 700-1200 yuan/㎡
6. Cost-saving techniques
1.Simplify internal structure: Reduce unnecessary compartments
2.Standard size preferred: Non-standard sizes will produce more material waste
3.Mass customization: The same plate can be optimized for cutting solutions
Through the above detailed introduction, I believe you have mastered the calculation method of the cabinet expansion area. During the actual customization process, it is recommended to fully communicate with the designer to ensure that the calculations are accurate and to avoid additional costs in the later period.
