How to Measure & Install Your Blinds: Inside Fit vs Outside Fit

Inside Fit Blinds: Precision & Sleek Design

Inside fit blinds, also known as inside mount, are installed within the window frame, providing a clean, streamlined look. This option is often chosen for its modern appeal, offering a sleek and sophisticated design.

Things You'll Need: Pen, Paper, Measuring Tape

How to Measure Inside Fit Blinds: To ensure a proper fit, take precise measurements at three different points for both the width and height (or drop) of the window. Be sure to measure from the inside edges of the window frame. Select the smallest measurements to ensure accuracy.

Note: The manufacturer may make minor deductions to ensure the blind fits snugly inside the frame. If desired, you can reduce light leakage by mounting the blinds slightly deeper within the frame. To minimize gaps and enhance insulation, consider using ThermaCell Honeycomb Blinds.

Tip: Inside fit installation might allow some light to filter through the edges of the blind. For a more precise fit, consider positioning the blind deeper inside the frame.

Outside Fit Blinds: Versatile & Maximized Light Control

Outside fit blinds, also known as outside mount, are mounted on the wall or above the window frame. This option is ideal for those who want enhanced light control, increased privacy, and the appearance of larger windows.

How to Measure Outside Fit Blinds: Begin by measuring the dimensions of the window recess or frame, then add an additional 40-50mm allowance on all sides to ensure adequate coverage.

For the width measurement, focus on where the brackets will be placed, not the fabric width itself. No deductions will be made from the provided measurements.

Tip: Outside fit roller blinds are the best option for maximum light control and the flexibility to adjust the look of your window treatment.
