28.75 in x 48 in Cordless Room Darkening Mini Blinds - Black

Our review of these 28.75 in x 48 in cordless mini blinds finds them best for homeowners who want a custom-fitted, child-safe window treatment that reduces incoming light. The biggest reason to buy is the precision cut to ensure an inside-mount fit: Lumino ships each blind 0.5 in narrower than the frame size you order so the finished blind measures exactly 28.25 in, avoiding the common trimming or adjustment hassles that come with off-the-shelf blinds. For rooms that need extra privacy and light control, these perform noticeably better than standard light-filtering options.

Key Features

• Custom USA cutting: Each blind is precision-cut in the USA to the exact size ordered, giving a neat, built-in appearance without extra trimming.
• Room darkening privacy: Thicker 1 in vinyl slats filter more light than typical light-filtering blinds, improving privacy after installation.
• Cordless design: The cordless construction keeps cords out of reach for a safer environment for children and pets and creates a cleaner look.
• Water and moisture resistant: Vinyl construction lets these blinds be used in humid rooms like kitchens and bathrooms without warping.
• Inside mount sizing rule: The product is cut 0.5 in smaller than the listed frame size so an ordered width of 28.75 in yields a blind 28.25 in wide for an ideal inside mount.

Who It's For

These mini blinds suit renters and homeowners who need a neat inside-mount fit and want a low-maintenance, durable option for living rooms, bedrooms, bathrooms, or kitchens. They work well for families that prioritize safety, since the cordless design is certified best for kids, and for anyone who wants a straightforward installation without fabric care.

Shoppers who need complete blackout performance or decorative fabric textures should look elsewhere, since these are vinyl mini blinds focused on room darkening and practicality rather than full blackout or luxury fabric finishes. Also, if you need motorized or remote control operation, this manual cordless model is not a match.
