How to Measure for Double Roller Blinds

Achieving a perfect custom fit begins with precise measurements. When installing double roller blinds, accurate window dimensions ensure your shades operate smoothly and look beautifully tailored.

Follow this comprehensive guide to mastering the art of measuring for flawlessly fitting double roller blinds.

Gather Helpful Measuring Tools

Having the right gear makes getting accurate numbers simple. Have these items on hand:

Steel Tape Measure - Avoid stretchy cloth types

Pencil - Marks window frame lightly

Level - Checks surfaces are even

Screwdriver - Tests mounting sturdiness

Use a metal tape measure for the most precision. Cloth types stretch over time, skewing accuracy.

Decide on Inside or Outside Mounting

First determine whether you want shades mounted inside the window frame for a flush, built-in look or outside mounted above the frame to emphasize the window.

Inside mounts require very precise measurements to ensure a perfect tailor-made fit. Outside mounts allow slightly more margin for error.

Measure Width in Multiple Places

Measure window frame width at the very top, middle, and bottom. Note the narrowest width.

Provide the manufacturer this smallest dimension for shade fabrication to guarantee proper functionality clearing the window sides when operating.

Account for Shade Brackets

The stated window width must allow additional space for mounting brackets attached at both ends.

Add at least 1 1⁄2 inches onto total width to accommodate brackets without visibility beside shades.

Measure Height for Full Coverage

Height should extend from above the window frame all the way down to the sill. Add another 1⁄2 inch for a little overhang space at bottom.

Use the same height at all bracket locations for even shading. Note ceiling height as well for outside mounts.

Accurate measurements coupled with professional installation ensures double roller shades fit like a glove while functioning beautifully for years to come!
