How to calculate wardrobe door size
When customizing or purchasing a wardrobe, calculating the size of the cabinet doors is a key aspect. Accurate dimensions not only ensure the aesthetics of the wardrobe but also avoid problems during installation. This article will explain in detail how to calculate the wardrobe door size and provide structured data for reference.
1. Basic principles of wardrobe door size calculation

The size calculation of the wardrobe door is mainly based on the overall size of the wardrobe, the opening method and the material thickness. The following are common calculation methods and considerations:
| parameters | Description |
|---|---|
| total wardrobe width | To measure the overall width of the wardrobe frame, you usually need to subtract the thickness of the panels on both sides. |
| Door opening method | Swing doors or sliding doors, different door opening methods will affect the calculation of the cabinet door size. |
| Number of cabinet doors | Single door, double door or multiple doors need to be determined according to actual needs. |
| Cabinet door overlap | Sliding doors need to reserve an overlap, usually 50-100mm. |
2. Calculation of dimensions of flat door wardrobe doors
Swing doors are the most common way to open wardrobes, and the door size calculation is relatively simple. Here are the specific steps:
| steps | Description |
|---|---|
| 1. Measure the width of the closet space | The width of the wardrobe interior = total width - thickness of the panels on both sides (usually 18mm × 2). |
| 2. Calculate the width of a single door | Single door width = (inner space width + door gap) ÷ number of doors, the door gap is usually 2-3mm. |
| 3. Determine the door panel height | Door panel height = closet interior height - gap reserved at the bottom (usually 10-15mm). |
3. Calculation of sliding door wardrobe door dimensions
Calculations for sliding doors are more complex than for swing doors, as tracks and overlaps need to be considered. Here are the specific steps:
| steps | Description |
|---|---|
| 1. Measure the width of the closet space | The width of the wardrobe interior = total width - thickness of the panels on both sides (usually 18mm × 2). |
| 2. Calculate the width of a single door | Single door width = (inner void width + overlap amount) ÷ 2, the overlap amount is usually 50-100mm. |
| 3. Determine the door panel height | Door panel height = closet interior height - track height (usually 50-100mm). |
4. The influence of common materials on cabinet door size
Cabinet doors made of different materials vary in thickness and weight, which will affect size calculation and installation. The following are the parameters of common materials:
| Material | Thickness(mm) | Features |
|---|---|---|
| solid wood board | 18-25 | Thick and durable, more gaps need to be reserved. |
| density board | 16-18 | Economical and suitable for sliding doors. |
| glass | 5-10 | Beautiful but fragile and requires additional reinforcement. |
5. Things to note
1. Be sure to use professional tools when measuring to ensure accurate data.
2. Reserve appropriate door gaps to avoid door panel deformation due to thermal expansion and contraction.
3. The track of the sliding door needs to be of high quality to ensure smooth sliding.
4. When customizing cabinet doors, it is recommended to confirm the dimensions with the manufacturer to avoid errors.
With the reference of the above steps and data, you can easily calculate the size of the wardrobe door to ensure the practicality and beauty of the wardrobe. For further assistance, it is recommended to consult a professional designer or installer.
