MEASURING INSTRUCTIONS FOR TWILIGHT ROLLER SHADES.
When to use Inside Mount:
– When a ‘cleaner’ look of the window is preferred.
– When there is nothing obstructing the operation of the blind.
– When there is enough depth to mount fascia inside (min. depth 1½”, flush with top 2½”, flush w front 3 ¼ ”)
– When some light leakage from the sides won’t be a problem
(note that the fabric of the shade will leave a ½ inch gap on the side of the chain control and 1/8” on the opposite side. Therefore, depending on the width of the glass in your window frame, there might be some light leaking from the sides. For applications that require total light control it would be better to measure for an outside mount if possible.)
Width: Measure the Inside Width at the top, middle and bottom of the window. Record the shortest measurement to the nearest 1/8 of an inch. (note: the fabric will be ½ inch narrower than the fascia on the side of the chain control and 1/8 inch narrower on the opposite side!)
Height: Measure the Inside Length/height of the window at the left, middle and right. Record the shortest measurement to the nearest 1/8 of an inch.
When to use Outside Mount:
-When room darkening is important or complete light control is important.
-When there is not enough depth to mount fascia inside the window frame.
-When obstructions like handles or cranks will interfere with the blind.
Note: Outside mount brackets provide ½” clearance to clear the window frame when mounted on the wall above the frame. If the frame protrudes more than ½”, order your shades with spacers for a total of 1” clearance (mention this in comment section for each shade that requires this, there is no extra charge).
Outside Mount on the Window Frame with Protruding Windowsill:
Width: Measure the outside width at the top of the window frame up to the nearest eighth of an inch.
Height: Measure the Outside Length/height at the left, middle and right. Record the shortest measurement to the nearest 1/8 of an inch.
Outside Mount on the Window Frame without Window Sill:
Width: Measure the outside width at the top of the window frame up to the nearest eighth of an inch. If you wish the fabric to completely cover the window casing, add 1 inch.
Height: Measure from the top of the frame down to the bottom of the frame to the nearest eighth of an inch.
Outside Mount on the Wall above the Window Frame:
Width: Measure the outside width of the window frame at the top to the nearest eighth of an inch. If you want the blind to overlap beyond the sides of the window frame or window opening for complete light control add extra inches to this measurement.
Height: Mark on the wall where you wish to mount the blind above the window frame (A). Also mark on the wall to where you wish the blind to hang when fully lowered (B). Measure from A to B and round to the nearest eighth of an inch.
