16 Jul How to Measure for a Door

If you’re replacing an old door or installing a brand new one, getting accurate measurements is important. A correctly fitted door improves insulation, security and the appearance of a home. Below is a guide focusing on how to measure for a door and how we can help at Park Lane Windows.

 

The Importance of Accurate Door Measurements 

A front door that doesn’t fit correctly can cause draughts, reduced efficiency and risk of security at home. To prevent this, be precise when measuring the door frame.

 

Three Methods to Measure a Door

Below are the three most common methods for measuring a new door.

1 – Measuring the current door – If it fits well already, you can use these measurements as a reference.

2 – Measure inside the frame – This is ideal for replacing a door but keeping the current frame.

3 – Measure brick to brick – This method is used when replacing both the door and frame.

Always measure in millimetres (mm) and take measurements for width and height to ensure accurate results.

 

Step-by-Step: How to Measure for a Door 

Measure with Width 

Measure the internal width when measuring the door frame from one side to the other at the top, middle and bottom. Record the largest figure to ensure you get the right fit when learning how to measure for a door.

Measure the Height 

Measure from the floor up towards the top of the frame on both sides. Using the larger number for accuracy is important for installation and insulation when measuring door frame dimensions.

Measure Brick to Brick 

If you’re installing a new frame and door, measure across the brick opening horizontally and vertically. This method is an important part of understanding how to measure for a door without an existing frame.
