Shutter Measuring Guide for Curved Bay Windows

This information will help you successfully measure your shutters. If possible please print this in colour to help you clearly see where you should measure.

1. Each window in the bay gets its own individual frame. The panel or panels are hinged inside each frame.
2. Due to the angle of the bay there will have to be deductions made when measuring the width of each window. This then allows the frames to butt up to each other and the panels will open and close without restriction.
3. It is recommended that you use our small templates which replicate the size of the frame, these are available on the site to print off. Position the template on the window sill as shown in the photo and sketch. When you are happy that all frames when installed will butt up to each other......Measure the widths required.
4. When measuring for the drop it is important that all frames are ordered the same height for each window. This ensures that all panels have equal number of slats and that shutters have equal top and bottom rails.
5. The width of the frame that you need to template is 33mm and the depth of this frame (how far the frame comes from the window into the room) is either 57mm or 67mm. The depth you choose depends on the slat size you go for and if there are large handles on the window that you need to clear.
6. If you want to include a midrail in the panels, measure up from the sill to the mid point on the window where you want the rail centered. Again, this should be the same measurement on all windows in the bay. If there is a divide or rail on the actual window it is always best to mirror this location on the shutter panels. This is normally in the middle or 3/4 way up the window.
7. Use a steel tape measure and always measure in a couple of places on every window to ensure it is square. If the window is not square always choose the smallest measurement it needs to be.

If you would like further advice on your actual window, please email a clear digital image to hello@thecaliforniacompany.co.uk. Ensure all curtains are moved away from the window and that handles and the full window is in the photo.

The green lines above show where your shutter frames will be mounted.
You need to measure as indicated by the black arrows.

Remember – the dimension you give to us includes the frame itself.

If ordering full height panels with a mid rail please measure to the blue line to ensure the mid point of the mid rail is at the mid point of the window transom.

If ordering café style or tier on tier shutters measure to the red line (the lower
panels will then cover the window transom).

To measure please refer to the instructions at the beginning of this section and use the templates supplied.

Before measuring, look for any obstructions on the window. You need to make sure that you avoid the possibility of the slats tilting open and hitting any obstacles such as handles or phone junction box.

We advise that phone points, if they sit in the way of the shutter frame, should be moved. This is generally the case with 3 section Victorian sash windows. However for handles, especially on UPVC windows, it is not easy to change these and you therefore need to ensure you measure correctly to accommodate the handles.

• Measure how far into the room the handles protrude.
• Depending on the slat size you choose check if you will have enough clearance or if you need to pull the frame forward.
• Remember, you can always order a deeper frame if you choose. For example a 4032 (67mm deep) frame for a 47mm slat. We can also custom make a non standard depth frame for additional cost.

Below is an example of how full height shutters with a mid rail look when installed.
