Should I choose curtain poles or curtain tracks for my bay window?

It depends on several factors, including the weight of your curtains, the style of your home, and how straightforward you want the installation to be. Both options have their benefits and drawbacks – read on to find out more.

Curtain poles

Curtain poles allow for a bolder statement. Available in wooden or metallic options, they come in a wide selection of styles and finishes. Curtain poles can hold more fabric, resulting in a fuller and heavier appearance – making them the ideal choice for heavier curtains, such as blackout or thermal lined curtains.

Curtain tracks

Curtain tracks are less visible than poles and offer a simpler, more understated look that blends seamlessly with your room’s decor. Our coil tracks are easy to bend and shape to fit your window, while our Thira tracks can be cut to size.


How to measure bay windows for curtain poles

Step 1: Measure the distance between the top of the window and the ceiling using a tape measure. If there is 15 cm or more, you can use a wall bracket or a ceiling bracket to fix the curtain pole. If it’s less than 15 cm, use a ceiling bracket, as it will be too tight for a wall bracket.

Step 2: Starting from left to right, measure the width of the first window in your bay to the angle of the next bay, and continue until you’ve measured all the bays. Write down your measurements in centimetres. Add an additional 20–30 cm to the first and last sides of your bay windows to allow for tucking back the curtains without blocking the window. Add up the total length of all sides for your complete bay window measurement.

Step 3: Measure the curtain drop length by finding the distance from where you’ll install the pole to where you want the curtains to sit. This can depend on whether you prefer your curtains to graze the floor or sit a few inches above it.
