How to Fit Double Roller Blinds

Achieving the perfect sizing and fit with your new double roller blinds will maximize their visual appeal and functionality. Unlike drapes that can conceal small fit issues, roller shades show every imperfection. Follow this comprehensive fitting guide for expertly tailored double roller blind results.

Select Suitable Brackets

Double roller blinds include installation brackets designed specifically to fit the headrail size. Two types are common:

Ceiling Brackets

Position shades well above window

Require ceiling mounting wires

Side Fix Brackets

Mount inside window frame

Quick and simple install

Side fix brackets keep shades flush inside the frame for a seamless fit. Ceiling mounts emphasize the window area better visually.

Measure Width Precisely

Use a steel tape measure to gauge window width at top, middle, and bottom. Record the narrowest dimension.

When ordering blinds, provide the manufacturer this exact measurement for a custom fit. Avoid rounding up - even 1⁄4 inch larger can hinder functionality in the frame. Always size down for accuracy.

Account for Bracket Space

The stated window width must factor space needed for mounting brackets on the ends.

Each bracket requires 11⁄2 to 2 inches of additional width. This prevents any hardware visibility beside shades when installed.

Consider Inside vs. Outside Mounts

For a flush, tailored fit relying on the window frame, opt for an inside mount fixing brackets within the frame. Outside mounts require more measuring precision.

Inside mounts also provide superior light blocking by eliminating gaps above or beside shades.

Confirm Shades are Level

Check that brackets mount evenly spaced and level so headrail tracks straight. Use a bubble level often during the install. Any tilting causes operation problems and looks unprofessional.

Adjust Limits for Proper Roller Coverage

If shades don't roll up/down fully even with perfect width sizing, adjust the upper and lower travel limits. This synchronizes the roller length to your window height.

Correct limit settings makes for smooth functionality and an elegantly framed window treatment when closed. Take the time to size and fit shades right.
