How to Measure for Blinds, Shades, and Shutters

Learn how to measure windows for blinds, shades and shutters with our user-friendly guides. Follow along with quick video tutorials, or view step-by-step written instructions.

Important Note: For all measurements, record the exact size of the window opening. Do NOT make any deductions.

Inside Mount

  1. Make sure your window has enough depth for the product you have chosen (see the "Mounting Requirements" section for your product). If your window does not have sufficient depth, select another product or an outside mount.
  2. Measure width. For Roller Shades, Sheer Shades and Vertical Blinds, record the width at the top of the window only. For all other window coverings, record the top, middle and bottom measurements, using the smallest of the three for your width.
  3. Measure height at the left, middle and right sides. Use the shortest measurement of the three for Sheer Shades, Vertical Blinds and Shutters.

Outside Mount

  1. Measure the width and height of the area you want your blinds to cover. Your product will be made to the exact measurements you specify. For roller shades, consider adding more width than with other products.
  2. Include additional height for the mounting brackets, which are up to 2 1/2" tall.
  3. Take note of obstructions like alarm systems, molding, doorknobs and deadbolts that might get in the way of your window covering. Some products are available with spacer blocks or extension brackets to help clear these obstructions.
