We always advise that you measure the curtain track or pole width, not the window.
If you are fitting a new track or pole this should extend 15cm to 20cm either side of the window. This will allow the curtains to be stacked either side of the window.
Measure the length of the pole between the finials(decorative ends).
Measure the length of the rail. If you have a rail with an overlap in the centre, measure the length of the rail and add the length of the overlap to this measurement.
The length of your curtains will depend on your preference. Typical length measurements are as follows.
A: Full length which is approximately 1.5 to 3cm above floor level
B: Above radiator typically 1 to 3cm above the radiator.
C: Below the window sill typically around 15cm.
Measure from the top of the track or bottom of the curtain rings for a curtain pole to the desired length of your curtains.
Tab Top & Eyelet Curtains
For Tab Top or eyelet curtains you should take your measurements from the very top of the pole.
Pencil, Pinch & Wave Pleat
Measure from the top of the track or bottom of the curtain rings to the desired length of your curtains.
Once you have entered your curtain pole or rail width, we will calculate the amount of fabric required for your curtains. Some headings require more fullness or gathering than others so these headings will require more fabric which is reflected in the price of the curtains.
All curtains are made in increments of 1/2 widths:
Pencil Pleat 1.75
Pinch Pleat 2.25
Wave Pleat 2.0
Tab Top 1.5
For example, for a pole length of 120cm and for pinch pleat heading we would recommend using at least 120cm x 2.25 = 270cm flat width of fabric. If the curtain fabric which you have chosen is 140cm wide then we would recommend using two widths of fabric either one at each side of the window for a pair of curtains or two widths joined together for a single curtain.
