When buying curtain poles, the longest you are likely to find will be extendable curtain poles. Extendable curtain poles can reach up to 500cm in some cases where they are needed for patio windows or bi-fold doors.
If you need a curtain pole that is longer than this, you may be able to order bespoke curtain poles that suit your project, but this is likely to involve higher costs and longer delivery times.
For the average window space, curtain poles between 120 and 210cm in length are sufficient. Read on for more information about choosing the right curtain pole length for your project.
How long should a curtain pole be?
To ensure the curtains cover the window fully when closed and can be pulled back completely to expose it, you need to know the window’s dimensions.
A good rule of thumb is to measure the width of the area above the window to decide where the pole should be installed and add 15-20cm at either side.
Rather than buying poles that are just about long enough, it is generally better to choose longer poles that can be shortened if needed, or extendable poles that offer flexibility.
What is an extendable curtain pole?
Unlike standard curtain poles, an extendable curtain pole can be lengthened or shortened to fit the window size, without having to cut it. This is because they are made up of two poles, one of which is slightly smaller in diameter so it can slide inside the other like a telescope.
Extendable curtain poles are a popular choice for many organisations because of the flexibility they offer. You will not need to buy curtain poles that are too long only to have them cut down to a shorter length – the pole can easily be adjusted to the required length.


This avoids the expense, hassle and costs of getting curtain poles cut to a bespoke length but also means that poles could be used again in another setting where a different length is required.

What diameter curtain pole do I need?
In addition to the length of your curtain pole, you need to check its diameter as this will determine how much weight the pole will be able to hold. The more weight you add to the curtain pole, the larger the diameter needs to be, so it may be worth confirming the fabric and style of the curtains before purchasing the poles.
In the case of extendable curtain poles, they are usually better suited to light or medium-weight curtains. This is because the different sections of an extendable pole have different diameters, and excessive weight can cause stress and friction where the different sections of the pole meet. At Homefords, we offer a heavy-duty curtain pole with a 28mm diameter, while all our other curtain poles have a diameter of 19mm.
