It is important that you measure the length of the curtain track or pole and use this as your curtain width. We will use this to work out the curtain fabric. Handy Tip – if you are fitting a new track or pole, we recommend you extend it between 150-200mm on either side of your window and at least 150mm above the top.
For your width, take the distance of your pole between any end caps/finials.
For your width, measure the full length of the track from end to end.
Measure the full length of the track from end to the overlap (a) plus the length of the overlap (b). Add the two distances together for your width. Note the track without overlap can be measured as normal.
