Terminology of Window Blinds and Windows The below section defines some of the key words used in comminicating how a blind is to be fitted.
Window Blind Stack size is important to understand because this may influence where a blind is fitted and the size that you request. There is no point for instance putting a Roman Blind in a doorway reveal that has 2100mm height because it will reduce the door clearance down to around 1770mm meaning you will need to duck to get through the door. Instead because you now are aware of stack height, you would probably put the blind above the doorway.
When a window blind is installed, it will project out from the wall by a certain distance. The amount a blind projects out at the top may be different to how it projects out at the bottom when it is fully down.
