However if you are a die hard do-it-yourselfer, here are three easy way measure and determine if a window is square:

1.  Get a carpenters square. First,

2.   Place it in the bottom left corner of the window.  If a gap is visible between the side of the window and the square, a left control will be best.

3.   Place the square in the bottom right corner; if a gap appears, a right control will be best.
