There are hundreds of thousands of UK residents unsure of how to measure double glazing units, but you’re not one of them.

Or at least you won’t be after reading this step-by-step guide from the Maghull Double Glazing blog team.

It can be a daunting prospect, but with our help, it is a process that you can approach with confidence.

With that in mind, let’s get to it.

The Steps Involved in Measuring Your Double Glazing Units

Following these simple steps will see you through the process in no time. Our main advice would be to take your time, and make sure that you are happy with your measurements before giving them to a professional.

The last thing you want to do is to give the wrong fitting sizes to a tradesperson, but that shouldn’t be an issue if you follow the below steps.

Always Measure From the Outside

You’d be amazed at the number of people who don’t know to measure their windows from the outside. If you are one of them, don’t be ashamed, you’re far from alone. In the vast majority of cases, windows and doors are fitted from the outside, so the measurements taken from the inside may not be completely in line with the fitting from the outside.

Brick to Brick

We can’t stress this enough – please do not measure your double glazing from the frames themselves. Do so from brick to brick, as measuring from the edge of the frame or the opening itself can result in incorrect measurements.

It is a common misconception that double glazing is measured on the fitting themselves. Industry experts will be able to tell you that the measurements are actually of the aperture. Differing materials frames, such as uPVC or aluminium, will vary in thickness and size, meaning that you can take incorrect readings if measuring from the window panel.

Take Three Measurements

If at first you don’t succeed, try and try again. It’s a catchy saying, but not quite what we mean here. We’re sure your first measurement will be absolutely fine, but taking three different measurements takes away any element of doubt.

When measuring the width of your windows, take one from the top, one from the middle and one from the bottom. The average of the three will give you your correct measurement.

Similarly, when measuring the height, do so from the left, right and centre.

Include Your Inclusions

Sounds obvious, but don’t forget your inclusions. Be sure to include the height and the width of the frame, the window cill and any additional fittings that you may have originally opted for. It all adds up, and helps to give the professionals an accurate measurement.

Take the Height Measurements From the Floor to the Window

The final step is another important one. Be sure to check how far from the floor your windows are. Start from the bottom of the cill itself, measuring straight down to the floor. If the distance is less than 80cm, you’ll require reinforced glass.

What to Do If You’re Unsure of the Process?

Hopefully, after reading this blog, you are confident in how to measure your double glazing units. However, we’re only too aware that some people may still not have the confidence to carry it out, or are simply unable to.

We completely understand, a minor mistake can easily result in a wasted unit, potentially costing you time and money.

Maghull Double Glazing offer full technical surveys that include sending in one of our professionals to not only carry out the measuring, but advise you on your double glazing requirements.

Why is it so Important to Know How to Measure Your Double Glazing?

Quite simply, doing so incorrectly can cost you both financially and with your precious time. Measuring is the very first step, and as we all know, the first step is often the most important. Get it wrong from here, and the entire process is worthless.

It is also worth pointing out that incorrect measurements can result in poor performance in terms of noise reduction and energy efficiency. Yes, if your measurements are only slightly out, there is a chance that the windows can still be fitted, but who wants that if they aren’t going to properly perform the basic functions that they are intended for?
