Hi McGill.......sorry for the delay in getting back,
Lounge Window .........2420 drop X 2080 width
Bed 1 2420 drop x 1580 width
Bed 2 1800 width (no drop as it they are a small window, high level, above the bed.
In the lounge the blind case is above the window so the Pole needs to be above that (due to centre mounting bracket), My advice would be to fit Pole / Track in the lounge & then measure - just to be on the safe side
Cheers
Nick
