How to measure an internal door
At Howarth, most of our internal doors
fall within a range of conventional sizes, so it's crucial to select the right
size for your door. Measuring up for a new internal door is an important step
in ensuring a correct fit, so we've put up a brief guide to walk you through
the process.

For measuring a door, the 3 things you will need are:
2. Pencil
3. A piece of paper
Helpful tip: If you are buying replacement doors, DO
NOT
measure the existing door. You must always base your measurements on
the door frame itself.
Step 1: Measuring the height
The first thing to do when measuring an internal door is to take a measurement of the inside of each vertical side of the door frame. It is important to measure both sides of the frame since each side may not be symmetrical. Ultimately, the longest length will determine the door's height.
In the UK, the most common door height is 6'6/1981mm, but some may also be 2040mm high.
Step 2: Measuring the width
After that, start measuring at the top corner and work your way across. Repeat this across the middle and at the bottom.Use the widest measurement to ascertain the width of your new door.
Step 3: Measuring the thickness
Lastly, to determine the thickness that your frame will allow,
measure the frame rebate where the door will sit after it is closed.
Most doors have a standard thickness of 35mm, however particular areas, such as
a kitchen or garage, are likely to have
fire doors installed. Fire doors are typically 40mm or 44mm in thickness.
Door Measuring Tips
- Use the dimensions shown above to ensure a perfect fit. Also make sure to double-check all measurements before making a purchase.
- If you're installing new frames, you might be able to make changes to accommodate common door sizes and prevent the requirement for custom doors.
- Don't forget to examine how the door opens and take that into consideration. If the floor is uneven or varies on each side of the door, it may impair the ease of opening.
- Consider the finishing touches you intend to add, such as hinges and handles.
