How to calculate how many boards to use for a wardrobe?
When customizing a wardrobe, calculating the amount of boards is a key step to ensure cost control and rational utilization of materials. This article will combine structured data and actual cases to help you quickly master calculation methods.
1. The core formula for calculating wardrobe boards
Total board usage = Wardrobe expansion area ÷ Available area of a single board × Loss coefficient (usually 1.1-1.2)
| Calculate elements | illustrate | Sample data |
|---|---|---|
| Expanded area | The sum of the planar areas of all panels | 2.4m high wardrobe is about 6-8㎡ |
| Standard plate size | Common specifications: 1220×2440mm | 2.97㎡/sheet |
| Utilization | Actual usable ratio | About 85%-90% |
2. Step-by-step calculation demonstration (taking a 2m wide × 2.4m high wardrobe as an example)
| Part name | quantity | Dimensions(mm) | Area calculation |
|---|---|---|---|
| Side panels | 2 | 2400×600 | 2×2.4×0.6=2.88㎡ |
| Partition | 4 | 2000×600 | 4×2×0.6=4.8㎡ |
| Top and bottom plate | 2 | 2000×600 | 2×2×0.6=2.4㎡ |
| backplane | 1 | 2400×2000 | 2.4×2=4.8㎡ |
| Total total area | 14.88㎡ |
3. Conversion of plate quantity
| Calculation project | formula | result |
|---|---|---|
| Theoretical dosage | 14.88÷2.97 | 5.01 photos |
| Actual dosage | 5.01×1.15(loss) | 5.76 photos |
| final purchase quantity | 6 pictures (rounded up) |
4. Supplementary explanation of influencing factors
1.Design complexity: Curved and special-shaped designs will increase material loss by 5-15%
2.Door opening method: Sliding doors save about 0.5-1 sheets than flat doors
3.Board thickness: The back plate usually uses 5-9mm thin plate, and the main body uses 18mm thick plate.
| thickness type | Applicable parts | Usage conversion factor |
|---|---|---|
| 18mm | Main structure | 1.0 |
| 9mm | backplane | 0.6 |
| 5mm | decorative panel | 0.3 |
5. Practical suggestions
1. Use professional design software (such as AutoCAD, Kujiale) to automatically generate an accurate bill of materials
2. Reserve 5% margin in advance to deal with installation errors and subsequent maintenance.
3. Consider adopting the "standard size first" principle to reduce plate cutting waste
Latest industry trends (hot spots in the past 10 days)
1. A certain brand launched an “intelligent material calculation system”, claiming to reduce material waste by 8%
2. The price of environmentally friendly panels fluctuates significantly. It is recommended to lock in the purchase price in advance.
3. The newly released "General Technical Conditions for Customized Furniture" in 2024 puts forward higher requirements for the utilization rate of panels.
Through the above structured calculation method and real-time data reference, you can more accurately plan the amount of wardrobe panels, which not only avoids insufficient materials and delays the construction period, but also prevents waste caused by over-purchasing.
