Will This Window Treatment Fit My Window?

These window treatments are custom-made to fit most windows. If your window size falls within the width and height range listed below, you’re off to a great start!

• Inside Mount: Your window opening needs a minimum depth to hold the brackets. If your opening is deep enough, you can achieve a flush mount look where the treatment sits entirely inside the opening. Note: If your depth is between the minimum and flush requirements, your treatment will still install securely but may stick out slightly from the window opening.
• Outside Mount: This installs on the wall or trim above your window. It’s ideal for total light control, especially if your windows are not deep enough for an inside mount. Ensure you have enough flat surface space to install the mounting brackets.
