How to calculate cabinet door size
When customizing or replacing cabinet doors, accurately calculating dimensions is a critical step. Whether it is a wardrobe, cabinet or bookcase, size errors may cause installation difficulties or affect the appearance. This article will introduce in detail the calculation method of cabinet door size and provide structured data to help you quickly grasp the key points.
1. Basic principles of cabinet door size calculation
When calculating the size of a cabinet door, factors such as the cabinet frame, hinge type, and door panel material need to be considered. The following is the core calculation formula:
| parameters | Description | Calculation formula |
|---|---|---|
| Door panel width | Single door horizontal width | (total width of cabinet - sum of gaps) ÷ number of doors |
| Door panel height | Single door vertical height | Cabinet interior height - top/bottom gap |
| gap reservation | Gaps between and around door panels | Reserve 2~3mm on each side |
2. Specific calculation methods for different cabinet types
1.Swing door wardrobe: Please pay attention to the space occupied by the hinge. Usually the width of a single door does not exceed 600mm.
| Overall width of cabinet | Number of door leaves | Recommended single sash width |
|---|---|---|
| 1200mm | 2 fans | (1200-6)÷2=597mm |
| 1800mm | 3 fans | (1800-8)÷3≈597mm |
2.sliding door wardrobe: It is necessary to calculate the overlap of the track. Usually door width = cabinet width + overlap amount (100~150mm).
3. Comparison of size characteristics of popular materials
| Material | Recommended minimum thickness | Maximum unsupported width | Thermal expansion and contraction coefficient |
|---|---|---|---|
| solid wood | 18mm | 800mm | A 5mm gap is required |
| particle board | 16mm | 600mm | A 3mm gap is required |
| glass | 8mm | 1200mm | Neglect |
4. Measurement tools and precautions
1.measuring tools: It is recommended to use a laser rangefinder, and the error should be controlled within ±1mm.
2.triplicate measurement method: Measure the top, middle and bottom of the cabinet and take the minimum value.
3.Special reminder: If the ground is uneven, an additional 5~10mm adjustment gap needs to be reserved.
5. Latest trend data in 2023
| trend characteristics | Proportion | Recommended sizing |
|---|---|---|
| Minimalist handleless design | 42% | Door panel heightened by 20mm |
| Glass door mix and match | 35% | Single fan width ≤500mm |
| Intelligent electric opening | 18% | Reserve 50mm circuit space at the top |
Summary: Calculation of cabinet door size requires comprehensive consideration of functional requirements, material characteristics and installation environment. It is recommended to make a 1:1 template for pre-installation testing, especially for high-priced customized materials. Save the original measurement data for later adjustment and maintenance.
