Please measure your window accurately in advance. For outside mounting, the shade should be 4 inches wider than the window width. For a 30"" wide window, choose a size 34"". For inside mount installation, order 30"" or slightly less. Don't worry about the blind's height, it is adjustable from 0"" to 84"". Please note that the fabric width will be 1"" less than the frame size. For complete window coverage, outside mount is recommended.The key to perfect room decor is in the final touches with our Day and night blinds.
