Doors and windows come in all shapes and sizes. The style of window covering you choose may be governed by a number of considerations
Shape of window, i.e. arched, triangle, etc.
These shapes will restrict your choice of style
Drapes will stack to side. If two curtains with
centre opening, curtains will stack on either side
of the window / door when opened. Blinds stack
up, you can install inside window frame, so stack

above the window allowing blind to clear the
If window or door opens into the room, window covering would need to clear the opening, either draw to the side onto the wall, or draw up above door. You need to ensure there is sufficient room for this to be achieved.
Sliding doors, again window covering needs to clear opening, either draw to one side across fixed panel of glass or draw high enough above door to enable movement through.
Wall to wall windows / doors and floor to ceiling windows / doors. Consideration needs to given to the installation of blinds or curtain tracks, also stack up and side stacking of blinds or curtains.
To eliminate light coming through above and to the sides of the window covering; installation of track or blind needs to go higher and wider than the window frame. Returns on ends of curtains, pelmets and valances will bring the curtain back onto the wall, further reducing the light filtering through, it also give a better finish.
When choosing tracks remember
that when curtains are open your track
is exposed, a standard rail track may
detract from the overall effect, a better
result would be achieved using a top
treatment, or a decorative track.
On a wide expanse, timber poles require a centre support bracket, this means that your curtains will not meet in the centre, and if made as one curtain, you will be restricted to opening from sides, meaning curtain would need to stack to the middle of the window.
