Measuring uPVC windowsHow to measure a window? Sounds relatively straightforward doesn’t. Just measure the gap and you done! Well if you take that approach you are likely to come unstuck, and it could spell disaster if you place an order with those measurements.

The first thing to realise is that the hole that your window sits in is unlikely to be perfectly square (what we mean by this is an exact rectangle or square), despite how well you believe your house is built.

Measuring uPVC windows

Currently, by far the most popular type of window is a uPVC window but the principle is the same for almost any material.

To get over the issues of the window openings not being square we have to take multiple measurements in terms of moth width and height. The first thing to understand is that the industry has a set way of listing sizes. When submitting sizes it is always the width first then the height so it is good practice to measure this way.

I would advise getting a piece of paper and writing at the top the type of windows that you are looking for, either casement or sash windows. Underneath this draw four columns and write Room, Width, Height and Depth at the top of each of the columns.

How to measure for windowsGenerally, most window openings will be reasonably square, As such you should be fine in taking three measurements in either direction. For the width you want to measure the opening at the very top of the window, in the middle of the window and at the very bottom of the window. On your paper put in the room name you are measuring and the jot all three measurements in the with column and circle the smallest measurement,this your window width. For the height you again measure in three places, the fare left side of the window, the centre of the window and the far right side of the window. Again, jot down the tree measurements and circle the smallest measurement,this your window height.

If your window is particularly wide (over 1500mm) then you may need to take two extra measurements for the height, midway between the left hand side of the window and the centre (basically a quarter of the way across) and midway between the right hand side and the centre. If the window is unusually high over 1500mm, you may also need to take extra width measurements. Please note you are always looking for the smallest measurement irrespective of whether you take 3,4 or 5 measurements.

It is also useful to take the depth of the wall measurement and fill this number into your fourth column.

After you have measured all of the rooms that you are looking planning to install windows in, write out on a second piece of paper all correct window sizes for width and then height using the smallest measurement that you got for each window.

Dont’ discard your initial measurements as they are likely to prove useful at a later date. It is good practice to keep or start project folder as you are likely to have accumulated quite a bit of information by the end of the project.
