Measure Once, Measure Right
Begin by deciding whether you will mount inside the recess or blinds cut to size on the face of the window frame. Inside-mount blinds typically sit within the opening, while face-mount blinds sit over the frame, changing both width and depth requirements.
Use a metal tape measure for consistency, and measure the width at three points: top, middle, and bottom. Record the narrowest width so the blind can fit without binding. Measure the drop height at both left and right sides, then use the longest measurement to avoid a blind that stops short of the sill.
Choose the Best Style for Your Space
Once measurements are clear, choose the blind type and operating style that suits how the room is used. For example, roller blinds work well for full light control, while venetian blinds provide flexible shading by tilting slats. If privacy is a priority, consider how much visibility you want through the slats when tilted to different angles.
Some retailers offer more standardized options, which may be suitable for simple window shapes, but custom-cut ordering is often better when your windows have unusual dimensions or include obstructions. If you have a bay window, an angled ceiling, or a window recess that isn’t perfectly square, plan for how each section will stack and overlap.
Plan Installation and Finishing Details
Before ordering, check the mounting surface and clearances where brackets will sit. Look for skirting boards, window handles, flyscreens, and any trim that could interfere with the blind hardware. A precise fit depends not only on window dimensions but also on whether the brackets can be screwed securely and aligned level for smooth operation.
Ask yourself whether you need additional finishing features, such as a light gap reduction strategy or a cleaner hem that helps the blind sit neatly. For venetian styles, confirm whether you want slat tilt control to remain easy and consistent across the full width. If the blind will be installed in a high-humidity area like a bathroom or laundry, also consider materials that resist warping and staining.
Conclusion
Start with careful width and height checks, decide on inside or face mounting, and verify that brackets will clear any obstructions.
