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 from the centre of that window/door frame to the inside edge of the window/door frame on the other side. Add 60mm to each of the outside blinds. Enter these measurements into the website. For the drop measurement simply measure from the top of the window/door frame to the floor, add 40mm and select “Outside Mount”. By adding the 60mm to each of the outside blinds this increases your chance of finding a timber stud behind the plaster. If you are fitting this way please let us know in the notes section of the ordering process,we will supply both longer screws to reach the timber and also hollow wall anchors so you can still fit your blinds even if there is no timber behind the plaster. 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, this will cost an extra $50 per set of links and these blinds cannot be operated individually.
