An important aspect of choosing and fitting a roof window
is ensuring that the window is placed at the correct height
for the occupants.
It should be stated that there is no one single "correct"
height - the window should be placed for the convenience and
functionality of the users, and this can vary according to
the conditions. A general rule however is that the lower the
pitch of the roof, the longer the window should be.
In this graphic we see illustrated how a steeper pitched roof
requires a shorter roof window than the shallow pitched roof.

Choosing the position of the window
Because the roof window has a centre-pivot hinge and a handle
at the base of the window you should ensure the window is placed
at a comfortable height for opening, typically between 90 -130cm
from the floor level.
