Set doors have become a popular choice for modern home decor. With an increasing number of set door products available in the market, it's essential to understand their dimensions before making a purchase. Today, we’ll explore the key details about the size of set doors, helping you make an informed decision.

Door Size Measurement
In China, the standard method for measuring a door opening involves using a 5-meter tape measure. First, measure the width at three points—top, middle, and bottom—and take the smallest value as your target width. Then, measure the height on the left, center, and right sides, again taking the smallest measurement. For wall thickness, measure the left, right, and top walls separately and use the largest value as the target. Keep in mind that the acceptable width tolerance is 40mm, and the height tolerance is 30mm.
Internationally, the process is slightly different. Stand 2000mm away from the doorway and visually check the verticality of the walls. Measure the width and height, ensuring they are the narrowest possible, while the thickness should be the widest. Use an international tape measure to record these dimensions accurately.

Set Door Height
When installing a standard door, here are some common requirements:
- Bedroom doors typically have a core size of 2000 x 800 mm.
- Living room doors usually come in 2000 x 700 mm or 2000 x 800 mm sizes.
- The general opening size ranges between 2050-2070 mm, with height adjusted based on the wooden floor thickness.
- For a door core of 800 mm, the width should be between 860-880 mm. A flatter opening reduces the adjustment needed for the door cover.
When measuring the door opening, the size of the door frame is determined first. The door core size is then calculated by subtracting the frame and accounting for the necessary installation space.

Advantages of Set Doors
1. Advanced Technology: Brand-name wooden doors often use large-scale production equipment, ensuring high-quality wood drying, finger jointing, flatness, and paint finishes. This gives them a clear advantage in door manufacturing.
2. Quick Installation: Many homeowners prefer a smooth and efficient renovation process. Set doors offer faster installation, shorter service cycles, and more comprehensive support, making them a convenient choice.
