How to measure the door set
When renovating a home or replacing doors and windows, accurately measuring the dimensions of a door set is a critical step in ensuring a smooth installation. Wrong dimensions may cause the door to fail to fit or become awkward to use. This article will introduce the measurement method of package doors in detail and provide structured data to help you quickly grasp the key points.
1. Preparation work before measuring the suit door

Before starting to measure, you need to prepare the following tools:
| Tool name | Purpose |
|---|---|
| tape measure | Measure the width, height and thickness of door openings |
| spirit level | Check whether the door opening is level |
| notebook and pen | Record measurement data |
| camera | Take photos of door openings for reference |
2. Measurement steps for set doors
1.Measure door opening width: Use a tape measure to measure the width of the door opening at the left, middle and right positions, and take the minimum value as the width of the door opening.
2.Measure door opening height: Measure the height of the upper, middle and lower positions of the door opening, and take the minimum value as the height of the door opening.
3.Measure door opening thickness: Measure the thickness of the wall of the door opening to make sure the thickness of the door matches.
4.Check door opening levelness: Use a level to check whether the door opening is level. If it is tilted, it needs to be corrected in advance.
The following is an example record table of measurement data:
| Measurement items | Measurement (mm) | Remarks |
|---|---|---|
| Door opening width (left) | 890 | Take the minimum value |
| Door opening width (medium) | 880 | |
| Door opening width (right) | 885 | |
| Door opening height (top) | 2100 | Take the minimum value |
| Door opening height (medium) | 2095 | |
| Door opening height (lower) | 2105 | |
| Door opening thickness | 160 |
3. Measurement precautions
1.Take the minimum value from multiple measurements: There may be irregularities in the door opening. Measure multiple times and take the minimum value to avoid oversizing the door.
2.Consider floor materials: If the floor has not been laid with flooring or ceramic tiles, a corresponding height needs to be reserved.
3.Check door opening for smoothness: The wall surface of the door opening should be smooth. If there are obvious unevenness, it needs to be dealt with in advance.
4.Reserve installation clearance: Usually, an installation gap of 10-15 mm needs to be reserved between the door and the door opening.
4. Popular door set size reference
According to recent market research, the following are common package door sizes:
| door type | Standard width (mm) | Standard height (mm) | Applicable space |
|---|---|---|---|
| bedroom door | 800-900 | 2000-2100 | Bedroom, study |
| bathroom door | 700-800 | 1900-2000 | Toilet, bathroom |
| kitchen door | 750-850 | 2000-2100 | kitchen |
| Entrance door | 950-1100 | 2100-2200 | main entrance |
5. Next step after measurement
After completing your measurements, you will need to:
1. Provide the measurement data to the door manufacturer or seller to confirm the door’s customized dimensions.
2. Ask about installation service details. Some businesses provide free measurement and installation services.
3. Confirm the opening direction of the door (left or right) to avoid customization errors.
4. Understand the material and style of doors and choose products that suit your home style.
Through the above steps, you can accurately measure the size of the door set, laying a good foundation for subsequent purchase and installation. If you are unsure about the measurement results, it is recommended to contact a professional for retesting.
