How to Measure for Curtains
The first step to choosing new curtains is measuring up. You can ask for one of our experts to come to your home and measure your windows for you, or you can take quick and accurate measurements yourself. Getting the right measurements for your curtains is easy, just follow our step by step guide.
STEP 1: WORKING OUT THE CURTAIN WIDTH
Before you begin, start by measuring your curtain track or pole.
For the best fit for your new track or pole, we recommend that it should stretch 15-30cm either side of the window (to allow the curtains to be stacked back off the glazed panels) and also 12-15cm above your window recess.
TO MEASURE FOR CURTAIN TRACKS:
Measure: From end to end = A
Do you have a centre overlap?
If you have a rail with a centre overlap measure the rail as above and then measure the overlap and add the two measurements together.
Measure: A + B = Total track width
TO MEASURE FOR CURTAIN POLES:
Measure between the decorative ends – C
It’s all about getting the right amount of gathering.
The correct sized curtains should have a natural gather even when fully closed. To get this gather right, we need to double your track or pole measurement and this number is the width measurement of the curtains we will make.
STEP 2: WORKING OUT THE CURTAIN DROP
There are three options to choose from: Floor Length, Below the sill and Above the sill. Since windowsills and floors can be uneven, it’s a good idea to measure at 2 or 3 different points and use the smallest measurement as your length.
Top Tip: For windows over radiators, curtains should ideally end 2-3cm above the top of the radiator so that the heat does not escape behind the curtain.
HOW TO MEASURE THE DROP FROM A CURTAIN TRACK:
Measure from the top of the track to where you want the curtains to finish.
MEASURING THE DROP FROM A POLE:
For pencil pleat, triple and double pleat headings, measure from the underside of the decorative ring, to where you want the curtain to finish.
MEASURING THE DROP FOR AN EYELET HEADING CURTAIN:
Eyelet header curtains will usually fit poles up to 63mm in diameter with the inner edge of the eyelet set down 3cm from the top of the curtain. The trick is to measure from the top of the pole to where you want the curtains to finish and then add 3cm.
Board width = A + B + C
Use the board width (not the curtain track width) to determine the size of valance required. This is normally approximately 30cm wider than the curtain rail is fitted to, due to the returns on either end. See diagram for details.
