How to Measure Face Fit Curtains
Before You Start
You will need the following:
Measure the width from the widest points of the architrave. This will be the length of your track. Your curtain will also be this width when closed.
Measure the drop from the top of the architrave where the track will be installed to where you would like the curtain to drop to.
If you want to just skim the floor measure 10mm higher than the floor.
The curtain when opened will have a stack of approximately 30% of the track width.
If this will obstruct too much of the window, then consider installing the track above the architrave on the wall. This means you can extend the width out past the architrave as well, just make sure you adjust your width and drop measurements accordingly.
Make sure you are not covering any light switches or security sensors when the curtain is closed.
