One step that has to be taken without fail is taking the measurement of the area to ensure that everything matches everything in the best possible way. The technique used for measuring them is slightly different as you will have to take into consideration, the back portion too. This consideration is important as the back portion would provide room for louver clearance and smoothen the operations of the shutters.
Establishing the square shape of the window
You need to take measurements diagonally from each corner ad see whether there is a diagonal difference in the overall measurement of the window. If this is the case, your window is out of square. If the difference is less than a quarter inch, it is good to go, but anything beyond this should be rejected straight away.
Inside mounting plantation shutters
In terms of inside mounted plantation shutters, you will first have to measure the height and the trim. It is worth considering if the drywalls or the trim narrow further back into the window opening and if it happens, you’ll have to take the narrower of the measurement to determine the place where you want to mount your shutters. No deductions are allowed and only the actual window opening is to be measured when you are measuring for inside mounting plantation shutters.
