Will This Fit My Window?
Our window treatments are custom-crafted to fit a wide variety of spaces. If your window dimensions fall within the ranges listed below, you’re already halfway there! Next, we'll help you check your mounting space, which may vary depending on the style you choose.
Inside Mount Installation
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 install securely but may stick out slightly from the window opening.
Outside Mount Installation
This installs on the wall or trim above your window. It’s ideal for total light control or your windows are too shallow for an inside mount. Ensure you have enough flat surface space to install the mounting brackets.

Every Blindsgalore custom window treatment is backed by a manufacturer's warranty because we believe in the quality of what we sell. But we also know a warranty is only as good as the people standing behind it. That's why when you contact us, you'll speak with a real person who understands your order, your home, and your needs — not a call center or automated system.
