Accurate measurements are key to achieving perfectly fitting roller blinds that elevate your space. For Inside Recess Roller Blinds, measure the window recess width and drop at multiple spots, taking the smallest values to adjust for any irregularities, ensuring a tight fit and effective light control. For Outside Recess Roller Blinds, measure beyond the window frame for complete coverage and a refined appearance. Use a metal tape measure, double-check your figures, and note them in millimeters. Properly measured blinds enhance aesthetics, privacy, and light management, providing a sleek, customized look for any window.
