General How-To on Measuring
Quick Tip: When measuring for blinds, be sure to measure every
window. Windows of different sizes can look deceptively similar.
Choosing Outside or Inside Mount
Before you start measuring, you'll have to decide whether you want
your blind to hang inside or outside your window frame.
If you're looking for
a flush, clean look, or if you've got attractive window molding
that you'd like to show off, you'll want to mount your blinds
inside your window frame. Inside mount blinds attach and hang
inside your window frame.
Blinds mounted outside
the window opening hang either on the wood frame itself or above
and beyond the wood frame. Outside mounting is a good way to make
a window appear wider and longer; you can also choose outside
mount if you need to hide an unattractive window.
Quick Tip: When you're
measuring for your blinds, use a metal tape measure and measure
to the nearest eighth of an inch (1/8").
Quick Tip: In order
to mount your blinds inside the frame, your window must be deep
enough to support the mounting brackets.
to 3 ½"
Measure the width of your
window at the top, middle, and bottom. Use the smallest width
measurement. The factory will make the necessary allowances for
the brackets. Measure the exact height of the window in 3 places.
If you're measuring for verticals, use the shortest height; otherwise,
use the longest height.

Enter the precise measurements on your worksheet. When you specify
inside mount blinds, a small width deduction will be taken at
the factory to give your blind room to rotate, open, and close.
If you want to mount your blind outside the window frame, measure
the exact width and height of the area you'd like to cover. Check
your measurements against the size of your window to make sure you've
added enough for sufficient overlap. (Don't worry if you can't give
as much overlap as we recommend. In most situations, we can still
make blinds that will work for you.)
