How to measure for curtains and blinds


Posted 27th Jan 2012

Buying new window dressings sounds like something that should be quite straightforward. That is until you come to measure and then you realize there are all sorts of things you need to take into consideration - such as whether you want blinds to sit inside or outside the recess, how to measure for a bay window and what to do if your floors are uneven.

To ensure you get the perfect fit every time, we have the following advice from The Natural Curtain Company.

How to measure for curtains


To avoid mistakes, your curtain pole or track should be in place already.

If you make calculations without a pole or track, you are more likely to get incorrect measurements. We advise you use a metal tape measure for accuracy. Measurements should be in cm to the nearest 1/2 cm. Please double-check your measurements.

If you have a pole, measure the distance between the finials (the decorative baubles at the end of a pole).

If you have a track, measure the total length of the track.


 

 


Measuring curtain drop
Before you start, you have to decide where you want your curtains to finish. For floor-length curtains, we suggest curtains 1.5cm longer than floor-length. If your floors are uneven, make sure you measure each side of the window and choose the longest measurement. For sill length curtains, we suggest either 15cm below the sill or 1-2cm above it.

Measuring drop for tab top and eyelet
For tab top or eyelet curtains, measure the drop from the top of your pole to where you want your curtain to finish. (Please note: tab top and eyelet headed curtains cannot be fitted to a track.)

Measuring curtain drop for pleated headings (all except tab top and eyelet)
The total drop for pleated headings is measured in two parts – the eye drop and the heading height.

Part 1. Eye drop

This is the distance from the eye (where the curtain hook attaches) to where you want your curtain to finish.




heading height

 Part 2. Heading height

The heading height is the distance from the eye to where you want the top of your curtain to be.

For tracks, we suggest a heading height just above the top of your track so that it is not visible above the top of the curtain.

For poles, we suggest a heading height from 2cm above the eye to just above your curtain pole according to your own taste. Curtains
will hang best with a smaller heading height.

 

How to measure for blinds


We advise using a metal tape measure for accuracy. Measurements should be in cm to the nearest 1/2 cm. Please double-check your measurements.

Measuring for Roman blinds in a bay window:
• Remember that your roman blind headrail will protrude from the sureface by 5cm.

• Where the angles of the window meet you must allow for the headrails to protrude - so don't measure all the way into the corner. Get a helper to hold a ruler or tape protruding 5cm and measure up to this point and deduct 1cm.

• Remember that the centre blind will have a headrail on both sides so deduct 1cm from each side for this blind.

• Think about where your strings/controls will hang. If you have four blinds you may want two to operate on the left hand side and two on the right hand side.

• We recommend having sidewinder operated blinds in bay windows because there are no cleats and strings to worry about.
 

The three scenarios for measuring blinds are:

Inside recess
Inside recess

• Measure width A-B at the narrowest point so your blind can hang freely

• Measure Drop C-D

• Note which side you would like the cord – right or left







Outside recess

Outside recess
First check for obstructions that might stop your blind hanging freely and then decide on the amount of fabric to overlap the top and sides of the window recess. We recommend at least 5cm for both.

• Measure the width you decide on, A-B

• Measure the drop you decide on, C-D

• Note which side you would like the cord – right or left





inside architrave


Fixed to window architrave (frame)
First, decide whether you want your roman blind to hang on the outside or inside edge of the window architrave.

• Measure the width A-B

• Measure drop C-D

• Note which side you would like the cord – right or left







outside architrave
