The Simple Guide To Measuring Your Door
Has the time come where you’re on the hunt for a new door to replace your existing one and you don’t really know where to start? It’s important to have a clear vision of what you want and need when you’re searching for the perfect door. Does it match your interior? What size door do you need? What colour? One of our most frequently asked questions, is how to measure a door. Now, although this appears to be an easy task, it’s something that can be wrongly done. Measuring correctly is essential in purchasing the right door, especially when it comes to installation. Imagine having a 7ft door delivered to your home when the door size you need is only 6ft in length– the installation process is going to be a bit off. This article does not act as a definitive instruction manual so we highly recommend that if you do require a new door to be installed, please contact a professional to do so.
Measuring Guide For Doors Fitted Into Existing Frames
If your existing door is still fitted, it's sensible to measure that as it will make the measuring process a lot easier. However, close the door and make sure your existing door has a good fit. If you don’t have an existing door fitted and you just have the frame, the measurements need to be taken from the inside of the frame. Carpenters and Joiners are known to allow different amounts of ‘tolerance’ around the edges of the door so it is worth checking with whoever will be hanging the doors.
What To Do?
Measure the height of the opening on both sides (this is marked as H1 and H2 on the graphic below) Measure the width of the door at the top and bottom Measure the thickness of the door that will be fitted
You should use the larger sets of measurements as the size you require. You will find that doors are available in standard sizes, so when it comes to choosing the right size for yours, you will have to choose the closest to your requirements. This, of course, applies to you if you’re not looking to have a bespoke door. Door measurements are usually listed as height x width x thickness.
A Quick Recap
- Measure width top
- Measure width bottom
- Measure height (left and right)
- Measure inside edge of the frame
Measuring Guide For Doors Without Existing Frames
If you don’t have a door or door frame in place, you can still take = measurements so it’s nothing to worry about. During this process, however, it’s essential to be careful as you’re not measuring against a door or a frame.
What To Do?
- Measure the height of the brickwork opening in 3 places – left, centre and right-hand side
- Repeat this process when you measure the width
If you have to order a new door frame, you need to allow a fitting clearance to ensure the frame fits into the door opening without any complications or damage. The clearance you should allow is 10mm. You can deduct this from your calculations to then find out what size you should go for when it comes to ordering a door and a frame. Frame thicknesses do vary, so you should check before you order.
