Measuring Instructions

Use these guidelines to help ensure your window treatments are a perfect fit.

Measure each window individually as size variances are common. Record WIDTH first, then LENGTH to the nearest 1/8". Measure WIDTH from left to right, LENGTH from top to bottom using a steel tape measure.

Horizontal blinds

Inside Mount

Inside mount blinds and shades are installed inside the window casing. Minimum depth requirements vary by product and headrail type.

1. Measure the exact inside WIDTH of window casing from one inside edge to the other in THREE different places. Record the narrowest measurement.

2. Measure the exact LENGTH in THREE different places from top edge of opening to top of sill. Record the longest measurement.

Outside Mount

Outside mount blinds and shades are installed outside the window casing, covering an area larger than the window itself.

1. Measure the exact WIDTH to be covered. Be sure the measurement overlaps the window opening by at least 1 1/2" on each side to ensure light control and privacy.

2. Measure exact LENGTH to be covered, including desired overlap.

3. The factory makes NO allowances on outside mount.

Vertical blinds

Inside Mount

Inside mount blinds are installed inside a window casing or door, wall to wall in a room. The window casing must be at least 2 3/4" deep for headrail flush mount or 3 3/4" deep for louvers flush mount. Otherwise an angle bracket may be necessary.

1. Measure the exact WIDTH of window casing from one inside edge to the other in THREE different places. Record the narrowest measurement.

2. Measure the exact LENGTH in THREE different places from top edge of opening to bottom, or top edge of sill if there is one. Record the shortest measurement.

Outside Mount

Outside mount blinds are installed outside of the window casing, covering an area larger than the window itself.

1. Measure WIDTH of window, including the frame if there is one. Add 3" for each side to ensure light control and privacy.

2. Measure LENGTH of window from top edge molding to bottom edge, or to top of sill if there is one. Add 3" to allow for adequate mounting area above the window.

3. If blind extends to floor measure LENGTH in THREE places, take the smallest measurement and deduct at least 1/2 " for clearance so the louvers don’t touch the floor.

Example above: (Inside)

The image above illustrates an exact inside(IB) measurement of 52 3/16".

Round this measurement to the nearest 1/8" which would be 52 1/8". (fifty two and one-eighth inches).

When ordering online, convert the 1/8" fraction to decimal.

So, the width you would enter when ordering online would be 52.125

This same rule applies for height.
