Matters to note when measuring the size of the doorway

Here are some important things to keep in mind when measuring the dimensions of a door opening: 

1. Accuracy: try to make sure that the measurement is accurate. Even a small margin of error can lead to problems with door installation.

2、Door type: Different types of doors (e.g. single, double, internal or external) require different sizes and installation methods. Make sure you choose a door type that suits your needs.

3、Door frame: Consider the width and thickness of the door frame as they will affect the final size and installation of the door.

4, Clear the space: When measuring the door opening, make sure there are no obstacles or furniture blocking the path of the measurement to ensure accuracy.

Measuring door opening dimensions is an important step when installing a new or replacement door. 

Make sure you use the right tools and methods and pay special attention to the accuracy of your measurements to avoid future problems and additional costs.
