Bay Windows Measuring Guide

Homes with bay windows have a special character. The great thing about bay windows is that they look gorgeous with any style home. For instance, a bay window could easily enhance a contemporary home just as it would a traditional home. Because of this, as well as the value this type of window offers the homeowner, they have become very popular in recent years.

Measuring Tips

To measure a bay window for an inside mount, you want to make sure that the measurements are exact and such to ensure the best light control and privacy. With this, you will find you have no annoying gaps, giving the bay window a beautiful, clean appearance. The goal here is to make sure shades or blinds meet in a corner but just so the front edges meet, meaning the shade or blind itself just a little bit smaller in width from that of the headrail.


First, you need to know the bracket depth for both headrail and bracket of the shades or blinds you intend to install. Then, you would be able to choose the type of window covering you need. For width, you want to measure from the left section of the window to the location where it meets with the center window. You will need to measure out the distance for blind or shade depth type being installed. We suggest you put a tiny pencil mark on the ceiling to help you keep track of the location. Now for the center part of the window where it meets the left section, measure again out the blind depth, making a red mark on the ceiling. Next, using the two marks made, this would be the location where the blinds or shades meet.

Right Section

Now for the right window section to the center, measure the blind or shade distance of what is being installed. Again, use a small mark on the ceiling to note the location. For the center part of the window meeting the right side, you will again measure the distance of the shade or blind depth, making a new, tiny mark. The location where the two marks meet is where the shades or blinds will meet, side by side.

The distance from the two marks is measured, deducting 1/8 of an inch, which now becomes the center blind or shade width. Then, measure from the left side of the wall to the first mark, again reducing 1/8 of an inch, becoming the left blind or shade width. You would do the same for the right side. Just remember, bay windows can accommodate literally, any type of blind of shade. Of course, if you have any questions, you can work with a professional from home improvement or window covering stores to assist.
