Simply measure from the inside edge of the window/door frame on one side to the centre of the first window/door frame. Then from the centre of that window/door frame to the centre of the next window/door frame. Then measure from the centre of that window/door frame to the inside edge on the other side. Enter these measurements into the website. For the drop measurement simply measure from the top of the window/door frame to the floor and select “Inside Mount” .These blinds need to be ordered as separate blinds. A good way to avoid having the chain on the centre blind hanging down in the centre is to have the blind over the door operating individually and the other 2 blinds to be linked. Linking the 2 blinds will allow you to lift both blinds together with the 1 chain, but this will cost an extra $50 per set of links and these blinds cannot be operated individually.
