IMPORTANT: You must use a steel measuring tape for accuracy. If you are replacing existing shades your measurements must be from measuring the window opening NOT the existing shades.

INSIDE MOUNT

WIDTH: Measure the width of the window opening in 3 places (top, middle, and bottom). Take the smallest of the 3 measurements (rounded to the nearest 1/8 inch) and write it down. This is the width you will order. Do not make any deductions! The factory will make a small deduction from each side to allow room to provide space for operation. Note for windows without a horizontal top frame (curved or arched top windows) that require a side-mount bracket you must deduct 1/4" from your actual width measurements before ordering to allow enough space for the side-mount brackets.

HEIGHT: Measure the window opening height in 3 places (left, middle, right) only this time take the largest measurement (again rounded to the nearest 1/8 inch). This is the height you will order. The factory will make no deductions or additions to the height measurement.

Outside (Wall) Mount Horizontal Shades
Outside mount shades are mounted outside the window opening and attach either to a wood trim/frame around the window or to a wall. Outside mounts are ideal for windows with little or no window depth. There is a minimum amount of flat space required for outside mount blinds (see chart).

OUTSIDE MOUNT

WIDTH: Measure the width of the window opening from left to right and add 4"to 6" for maximum light gap coverage and privacy. If the shade is to be mounted to trim or framing around the window measure from the trim's outside edge left to right. Once you determine the desired width (rounded to the nearest 1/8 inch) write it down. This is the width you will order. The factory will make no deductions or additions to your measurements on outside mount blinds. Please Note: On Cellular shades, the headrail/bottomrail endcaps add 1/4" to the overall width.

HEIGHT: To determine the height measure the window opening from top to bottom and add 2" to 4" inches to this measurement to allow space for mounting brackets above the opening and enough overlap at the bottom to avoid a light gap. You must add at least enough space to mount the brackets above the window(see chart) Once you determine the desired height (rounded to the nearest 1/8 inch) write it down. This is the height you will order. The factory will make no deductions or additions to your measurement. If there is trim or framing around the window measure from the trim's outside edge top to bottom and this is the height you will order, provided the trim provides the flat space required for an outside mount (see chart). If not you can mount the blind to the wall above the trim. In addition if the windowsill protrudes outside the window opening at the bottom of the window measure just to the top of the sill.
