When fitting vertical window blinds, measuring the window correctly is so important. Firstly you need to decide whether you want the blinds to be placed inside or outside of the window recess. Referring to diagrams of measuring the window for vertical window blinds, you can clearly see how having the blinds mounted either in or outside the recess will affect the size of the finished blinds. Therefore you must measure for the correct spot depending on which type of blinds you need.
