The following information is intended to provide general guidelines for measuring your windows for new treatments. Having a Hirshfield’s professional installer measure the project for you will produce the most accurate results.

• Be sure to use a metal tape measure for all measurements. Do NOT use a cloth tape.
• Measure the width dimension first, then measure the height dimension
• Measure to the nearest 1/8″.  For inside mount measurements, round down to the nearest 1/8″
• Don’t take any deductions. Factory deductions and adjustments will vary based on product and mounting selection

Inside (IB) Mount – Shade will be mounted within the window frame.
Outside (OB) Mount – Shade will be mounted outside the opening and will overlap the window.

Inside (IB) Mount
1. Measure the width inside the window opening in three places: top, middle and bottom.  If widths in the window vary, order the smallest width.
2. Measure the height inside the window opening in three places: left, center and right.  If heights in the window vary, order the longest height for horizontal treatments and the shortest height for vertical treatments. If ordering Dual Shades or Window Shadings, order the shortest height to allow for full rotation/operation of the bottomrail.

Outside (OB) Mount
1. Measure the desired width and height. To minimize light gaps, the shade should overlap the window opening at least 2″ on each side and at the bottom.
2. When measuring the height, be sure to allow for mounting the brackets/headrail above the window opening
