How do I measure for curtain poles?

Terry Baskeyfield | Posted

So, you’ve decided to purchase curtain rods or poles for your windows and you’ve done your research and chosen your colour, type and diameter of pole and you’re ready to make your purchase but now you’re wanting to know how to measure for curtain poles.

Hopefully by now you have already assessed your windows to make sure you can actually fit curtain poles and tracks to them and there are no reasons or restrictions why you can’t. If you haven’t, then hop over to our buying guide and take a quick look at: How do I know if I can fit a pole at my window? before you go any further.

Importance of accurate measurements

If you are going to the trouble and expense of ordering custom made curtain poles then you will be able to specify your exact finished pole length. The plus side to doing this is that your pole will come already cut to your specified length and you will not need to trim or cut it to size. You will simply need to correctly space and fit the brackets and then fit the pole, finials and curtain pole rings where appropriate. However, if you get your measurements wrong at all, custom made items are not usually returnable. Not a problem if your pole is too long, you will simply have to cut it down to size yourself and a disaster is avoided. But, if your pole is too short then there is little or nothing that you can do.

Measuring Window Width

How to measure your window for a curtain pole

  1. The first step is to consider how far you are going to take the curtain pole past either side of the window. You need to do this to create a stack-back area for the curtain to sit in when they are in the open position. If the pole only covers the window area then when the curtains are opened they will encroach onto the glass area of the window, block a lot of light and obscure your view.
  2. Should you have a window with a good wall space to either side then the norm with curtain poles is to take them a good 15 to 20cms (6” – 8”) to either side of the window. This measurement will increase for wider windows to allow the curtains to draw back away from the window.
  3. Next measure the required width taking into account the space needed for the curtain to be drawn back either side of the window (B).
Measuring Curtain Pole Width

Choose which style of finial you like, ensuring there is space for them either side of the pole. The finials are decorative finishing pieces at either end of the curtain pole, which also act as end stops to prevent the last curtain pole ring from falling off the end of the pole. They do not play any other part in supporting the curtains so do not need to be included as part of the final pole length measurement. Alternatively, where space is tight, please look for smaller finials or other suitable curtain poles.

Remember that when deciding on your size of curtain pole that you can widen the pole to change the size or aspect of your window. For example, a tall narrow window if required can be made to look more square with a wider pole.

What size should I order?

To be confident in ordering the correct curtain pole size for your window, we recommend that you order the nearest size to your calculated overall pole width measurement, but to always go to the nearest size up and not down. If your calculated pole size is only a few centimetres over one of the set pole sizes (e.g your measurement is 154cms and there is a set size option of 150cms) or if your calculated measurement falls halfway between two of the available size options, then always air on the side of caution and go to the next size up rather than leave yourself short on the pole width for the sake of saving a few pounds.
