Curtain Pole & Rail Measuring Guide

Choosing the best size curtain pole or rail is easy. The simple guide below offers a step by step guide. Nevertheless, if you still have any queries then please do contact us.
Please note that if you are replacing a curtain pole or rail, we advise that you measure the width of the existing fitting rather than the window.

Measuring: with an existing Pole or Rail

  • Our rails and poles can be easily cut to any size with a small hack-saw. If you don’t find the exact size you need, just order the one that is the next size up from your measurement.

  • Please note that the lengths stated do not include any finials. For example, if your curtain pole is 150 cm, and the finials are each 10cm, then the total length will be 170cm.

Existing Curtain Pole

Measure the length of the pole between the finials (decorative ends).

Existing Curtain Rails

Measure the length of the rail.

Measuring: for a New Pole or Rail

  • Our curtain poles are available with, or without rings. Each being suitable for curtains without or with eyelets respectively.

  • If you need additional curtain rings or hooks these are available as accessories.

  • We can also provide a range of matching holdbacks for the perfect finishing touch for your curtains.

New Curtain Pole & Rail

Measure the recess width of the window and then add at least another 15cm for each side - 30cm in total.

Pole Length = Recess Width + 30cm

New Curtain Rails

Measure the recess width of the window and then add at least another 15cm for each side - 30cm in total.

Rail Length = Recess Width + 30cm

Choosing Pole Diameter

When choosing a curtain pole from Poles Direct, the diameter will depend on the weight of the curtains. The table below offers a guide to selecting a suitably sized pole depending on the curtain weight.

Remember to take into account any extra weight such as linings. Also note that pencil pleat curtains will have a greater fullness than a curtain with eyelets for example so the weight will also be greater.

Up to 19mm Light weight (upto 4kgs in total)
25mm or 28mm Medium weight (upto 8kgs in total)
35mm or over Heavy weight (upto 12kgs in total)
Anything over 12kg please call 01924481711 for more details.
