Measuring for window treatments is much easier than most people think. Just follow these tips:
Choose Inside or Outside Mount
Before taking any measurements, step back from your window and decide if you want to mount the window treatment inside the window recess or outside on the wall or molding. For an inside mount, the window opening must have enough unobstructed depth to allow mounting.
Tip: For a flush inside mount (the blind completely recessed so that no part of the blind projects out of the opening) check that you have enough depth.When you specify inside mount, we will make a size deduction to allow for operating clearance. We will deduct up to 1/8" from each side (on vertical blinds there is also a height deduction of 1/4".)
The deductions are made so that the blind will not rub or scratch your window frame. If you specify an outside mount, we will not take any size deductions. Your blind will be made at the exact size you specify. So, you must add to the opening measurement to allow for overlap and mounting brackets. When measuring, don't be surprised it you windows aren't square. Many aren't. If they're a little out of square, it probably won't be noticeable.
Tip: If your window is out of square, consider an outside mounting to hide the window.
Inside Mount (IB):
Measure the opening width at the top, center and bottom recording the narrowest width. Measure the height left, right and the center, recording the longest height. We will take width deductions to allow for operating clearance.Outside Mount (OB):
Measure the opening width. If there is room add at least 3" to each side of the window opening for a minimum light gap and maximum privacy. Measure the opening height. Add a minimum of 2" in height to allow for mounting brackets above the opening and add your desired overlap fro the bottom.
Inside Mount (IB):
Measure the width top, center and bottom, recording the narrowest width. Measure the height left, right and center recording the shortest height. We will take size deductions to allow for operating clearance.
Measure the opening width. If there is room, add at least 4" on each side of the window opening to ensure minimum light gap. Measure the opening height. Add a minimum of 2-1/2" in height to allow for mounting brackets above the opening and add your desired overlap for the bottom.
