Roller Shades Measuring Instructions
Inside(Recessed) Mount Roller Shades
IMPORTANT NOTE: On roller shades the fabric will be 7/8" to 1" narrower than the tip to tip measurement (see pictures below). This allows space for the roller shade to operate properly and is true on all brands of roller shades. On all inside mounted roller shades you will have a 7/16" to 1/2" light gap on each side of the shade unless there is a window frame, trim, or drapery covering this space.

Inside mount refers to shades that are mounted inside the opening of a window that is recessed from a wall. This is the most common way to cover windows today and provides a nice, clean look. There is a minimum windowsill depth for shades mounted inside and there is also minimum windowsill depth for the shade to fit flush with the wall (see chart below).

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 deductions (see chart) to provide space for operation.

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 length measurement.

Outside (Wall) Mount Roller Shades
IMPORTANT NOTE: On roller shades the fabric will be 7/8" to 1" narrower than the tip to tip measurement (see pictures below). This allows space for the roller shade to operate properly and is true on all brands of roller shades. You may compensate for this by adding to your width measurement for an outside mount. On all inside mounted roller shades you will have a 1/2" to 5/8" light gap on each side of the shade.

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).

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.
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. Keep in mind that on roller shades the factory will make deductions from your measurements on both the barrel and fabric (see chart). Once you determine the desired width (rounded to the nearest 1/8 inch) write it down.

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 which are 1 1/2" tall on roller shades. 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.
