Finding a blind or curtain for a common window is easy, all you have to do is decide what type you want, how you want it to look, measure it up and visit any of the hundreds of shops or websites selling window blinds.
Blinds hung in a roof window or skylight require side rails, wires, or strain to hold them in place, as without them they would simply hang vertically, ruling out using normal blinds or curtains.

You also have to consider the fact that normal windows open outwards or slide vertically or horizontally, so window blinds or curtains can be hung on the outer dimensions of the window frame as the window won't interfere when opened.
However, most roof windows or skylights pivot in the middle when opened, which would be inhibited by a normal blind mounted on the outer frame. They have to sit inside the opening sash to allow them to be opened at will instead.
These blinds are flat and will shut out all daylight, some of the noise, and some of the heat. Blackout blinds are made to measure and fit inside the internal frame on aluminum side rails – do NOT buy blinds with plastic side rails as they will warp over time, leaving you unable to use the blind.
These fabric blinds are folded, concertina-style, into pleats, and run on a wire mounted into the internal frame of the roof window. Again, they are made to measure but are generally less sturdy than a blackout blind.
Providing the cheapest option for your roof window or skylight, roller blinds rely on tension to stay tight inside the window frame and are held in place by either wooden side pieces or by nailed in pegs/clips which secure the blind in position.
