ATTENTION PLEASE READ. We can customize these cordless blackout top down bottom up shades to the 1/8th inch. Once you click your size and color you will see a "Customize Now" button on the top right. You then type inside the window frame mount or outside the window frame mount and you exact measurements to the 1/8th of an inch. Order slightly larger sizes in the drop down before customizing. For example, if you need 24 1/2w x 48 1/2 order the 25w x 50h size and then customize it from there.
For an INSIDE THE WINDOW FRAME MOUNT, give us the exact measurement of the opening to the 1/8th inch and WE will take a 3/8 inch deduction off the exact measurement given so the shade will fit perfectly in that opening. The shade has to be slightly smaller then the opening to fit inside. Again we take the deduction so give us the exact opening to the 1/8th inch. You need at least 1 3/8 inch of depth at the top of the window for an inside mount.
For an OUTSIDE the window frame mount we take no deductions- provide us with the exact size you want. Outside mounts are traditionally mounted above the window opening, and go slightly wider than the opening. So make sure you add to the width and height for an outside mount.
