Double glazed bay windows are a very popular window to fit shutters on and many customers choose the DIY option. This means learning how to measure up, so to help, I have put together the following video blog.

This video shows you the basics of making a template out of an A4 piece of paper.

Bay windows can all vary in design especially at the sides where the window meets the wall. They can also have plastic infill’s and quadrant running around the frame, these can be removed or battens moulded around them to suit.

Making a paper template to help you measure is usually the same for each window, with just a few little adjustments, depending on the style of the window and surrounding plastic trim.

The idea of the template is to be able to accurately measure the shutter frame width. As most bays have large handles that protrude you will need to fit battens around the window first to space the louvre blades away from the handles. This means you have to allow for the battens when making the templates, the size of which depends on the handle depth.

There are also different frame depths depending on the material chosen and if you require the blackout option. The Standard and Standard Plus shutter frame is 46mm deep and the Elite and Basswood shutter frame are 50mm deep. When fitting blackout shutters the frame depth increases to 60mm or 64mm.

Once you have this information you can mark out the battens and frame depth on your templates which will allow you measure the width.
