Not sure how to measure your window?
Use a steel tape measure and measure your window from end to end. Then
install your track/rod to fit window width. Once track/rod has been
installed you can then work out the drop you need to cover window.
For curtain tracks measure from the top of the curtain track down to the
level you want curtains to hang.
For curtain rods, measure from the "eye" under the curtain ring to where
you want the curtains to hang.
A slight variance in drop can be achieved by the size of the type of hook
you use or if hanging pencil pleat curtain using the different hook
pocket levels. See how to hand your pencil pleat curtain.
