Why it’s important to measure curtains and blinds correctly

There are many reasons why it’s vital to get the measurements for your new curtains or roller blinds spot on. Aside from the obvious of your new window finishings looking a bit out of balance, other implications of mismeasurement include:

  • Heat will escape your home 
  • UV rays can beam through gaps and damage furniture
  • Curtains that are too short tend to make the ceiling feel lower
  • You may need to spend time and money on added alterations

In saying that, not all curtains or drapes need to touch the floor! Curtains and blinds come in different styles, whether living room curtains, bedroom curtains or bathroom blinds.  It’s good to get an idea of the style you’re after before considering measurements.


What you will need to measure curtains and blinds

Thankfully, you don’t need much to measure curtains, drapes or window blinds. When getting together tools or equipment, what you may need includes:


  • Tape measure
  • Pencil 
  • Paper
  • Calculator (most people have a calculator app on their smartphone)


Depending on the size of your window and how confident you are, enlisting a helper may be a good idea. Having an extra pair of eyes can keep you on track and double-check measurements.
