What you’ll need
- A steel tape measure (fabric ones are not accurate enough)
- Something to note the measurements
- Small step-ladder
Tips:
- Measure in centimetres
- Get someone to help – it can be very helpful to have a second pair of hands to hold the end of the measure, it will make it easier and more accurate
- Always measure at the place on the wall, or window frame, where the pole will be fitted.
- Don’t assume the bay is the same on both sides – it may not be!
- Allow 15cm or more at each end so the pole will pass the window.
Step 1 - How many sides does your bay window have?
The most common bays are 3 or 5 sides, but may also be 2 or 7

Step 2 - Measure the distance between the top of your window and the ceiling
This will determine if there is sufficient space for the brackets, or if you need to fix to the ceiling. A single-pole centre bracket will need a minimum of 3cm which gives a small clearance top and bottom. The passing brackets also require the same clearance. However, you will need to bear in mind the end brackets will require a minimum of 8cm

Step 3 - Draw out the shape of the bay and letter each point
Once you have drawn out the bay, starting with the letter A and letter each point clockwise as shown in the example 3 sided bay.

Step 4 - Measure the first side of your bay
Measure the width of the first side of your bay, where the pole will be fitted, along to where it meets the angle of the next section. Remember to start 15cm before the window frame so that the pole will allow the curtain to be pulled past the window when opened.

Step 5 - Measure the width of the next section
Measure the width of the next section of the bay and write down the measurement. Continue around the bay until all sides are measured. Remember to add the extra 15cm to the length of the last side of the bay. Then measure the width of the bay between the first and last points.

Step 6 - Take the cross angle measurements
Now take ALL the cross measurements. In the example shown there are only 2. If you have a 5 sided bay there will be 6 cross measurements.
If you are not sure which measurements to take, simply start at the first point and make sure you have a measure from there to every other point around the bay. Then do the same from the last point.

Step 7 - Cross angle measure on larger bays
If you have a 5 sided bay there will be 6 cross measurements. Simply start at the first point and make sure you have a measure from there to every other point around the bay. Then do the same from the last point.
n.b. The cross measurements are in red.
