How to measure for bay window blinds

If you have a bay window configuration, it may not seem obvious how best to measure for new window coverings. However, it’s not quite as tricky as it may seem and by following our guide, we’re confident you’ll get it spot-on first-time.

Measuring advice for bay windows

First and foremost, it’s important not to assume the two side window angles are both set at 135-degrees. While this is normally true, double checking the angles is a mandatory requirement before proceeding. This can be achieved with a variety of measuring tools, from smart phone apps to a good old protractor, pen and pencil! Once your angles are known, keep a record of them and progress to measuring.

Recess fitted blinds

If you’re planning on fitting your blinds within each of the bay window’s recesses, it’s important to be consistent in measuring from either the front edge or the rear of the recessed area but never from the midway point. This measuring point will need to be matched when installing the items provided.

To learn how to measure each window recess, use our guide for recess fitted blinds. Once you have recorded the width and drop (height) measurement for each window, you can proceed to placing your order…

When placing your order, each blind will need to be ordered separately with notes added specifying that the ordered product is part of bay configuration and advising the angle. We’d suggest adding something like this: “This is an order for bay windows and is the left / centre / right side window. The angle of the window is (add your details) degrees.” Armed with this information, we’ll make the relevant adjustment to ensure the products we supply fit snugly in the recesses.

We’d also strongly advise choosing ‘forward roll’ during the customisation process. This will help ensure everything looks neat, there’s less chance of the fabric catching on existing window handles or such like, and it also minimises any chance of fabric overlap if the fitting isn’t millimetre accurate!

Please note, with the standard adjustments, we’ll reduce the width of each blind to ensure all three butt together neatly. If you wish to have this done differently (i.e., no width deduction to the centre blind), please advise this requirement in your order notes or via a follow up email once your order has been confirmed.

Face fitted blinds

Much like recess fitting, the key information to obtain first is the angle each window is set on. As mentioned above, while most bay windows are set at 135-degrees (or very close to it), it’s important to check yours before proceeding.

When measuring each window, please follow our existing face fit measuring guide. Once you have recorded a width and height measurement for each window, you can proceed to placing an order…

Still not sure?

For any bay window requirements, feel free to email a photo of your space before starting so we can provide any specific advice. Also, with any clearly specified bay window order we receive, we’ll get in touch before we progress to manufacturing to check the requirements and ensure no adjustments have been made before we apply ours.
