Vertical Blind Measuring Instructions

Selecting the Type of Mounting

Determine whether the blind is going to be installed inside the window frame or outside the window frame.

Inside Mount (IB)

Inside mount installations are often preferred because the blinds take up less space in the room.

Measuring the Width and the Length for Inside Mount

For the width, measure across the top, middle, and bottom of the window opening. Using the narrowest dimension, measure to the nearest 1/8". By using the narrowest measurement the blind will operate correctly.

For the length, measure the up and down dimension on the left, center, and right side. Use the shortest length measurement, measuring to the nearest 1/8".

The factory will make any appropriate deductions. Do not make any width or length deductions.

Outside Mount (OB)

Outside mount installations are mounted on the wall or on the window molding. It is best to overlap the window opening at least 3" on each side when measuring for vertical blinds.

Measuring the Width and the Length for Outside Mount

Measure the area that the blind is to cover. For vertical blinds it is recommended to overlap the window opening by at least 3" on each side for a total of 6". To allow for enough space for the mounting brackets, it is also suggested that a vertical blind be installed at least 3" above the window opening.

Note: When outside mount blinds are specified, no factory deductions are taken.

Confirming Measurements

The most common error in ordering blinds is reversing the width and the length measurements. Always confirm that the width is the measurement that goes across from left to right and that the length is the measurement that goes from top to bottom.
