How to Measure

First, you need to decide how the blinds will be mounted. There are two ways to mount your blinds: inside mount and outside mount. The information below will help you to decide the best way to mount blinds on your windows.

Inside Mount

1. If you are selecting inside mount (mounting on the inside of the window frame), be certain there is enough depth for inside mounting. Refer to chart below.

2. Measure size of exact window frame opening (in other words the exact size of the inside opening of your window frame). Measure the width first, and then the height. The factory will fabricate the blinds to the correct size for clearance in your window frame.

3. Measure width of opening in three places, to the nearest 1/8th of an inch. Provide the narrowest measurement you took when placing your order (window may not be square).

4. Determine what type of window you have (sash, casement, etc.). If you have a casement window (window cranks, locks, and screens on the inside), consider outside mounting (on trim) to avoid interference with screens, locks, and crank handles. If inside mount is still desired, take extra precaution to make certain that consideration is given to locks, crank handles, and screens. Inside mount is ideal for sash (double hung) windows provided there is enough depth to the window frame.

5. If you are selecting inside mount for your sash (double hung) windows, make certain that the window track is not considered when checking depth. Blinds should never be mounted in tracks.

6. If you don't have enough depth for inside mounting, measure your windows for outside mount.

Outside Mount

1. If you have a standard beveled 2 1/4 inch trim, or 3 1/2 inch trim, you have the option of measuring for the first tier on the trim, or to the edge of the trim.

2. If measuring to the edge of the trim, measure from edge to edge across the top for the width, and from the top of the upper trim to the sill (or bottom of lower trim) for the height.

3. If measuring in the first tier, measure from the outer edge of the first tier on one side to the outer edge of first tier on the other side for the width, and from the upper edge of the first tier on top to the sill (or lower edge of the first tier on the bottom) for the height. See illustration.

4. If you do not have trim to mount to, then you will want to measure between the first available stud on each side of the window. You need to consider how far you want the blind to overlap the window on all sides and account for this. You will need to take into consideration the size of the mounting bracket when selecting what length to purchase.
