Fits window well. I wanted to install these inside the frame, not outside, but the directions said that 1.75" of window frame was required. I only have 1" available. I was still able to install these inside the frame without any difficulty. I am thrilled. These are easy to install and look lovely and operate well. I can't address their durability, I've only had mine installed for a few days and I don't open and close them much at all. I did however buy three more for the rest of my windows. The look is very nice, it affords me privacy, but plenty of light still filters in the room. The top of the shade isn't the prettiest, but shades never really are. These are no uglier than the top of a venetian blind or other shade. I am considering some kind of decorative window box or valence, though I don't think it's entirely necessary. All in all, I'm very happy.
