Direct Answer
Mini blinds are horizontal slat window blinds with 1-inch wide slats — narrower than standard 2-inch wood or faux wood blinds. They’re typically made from aluminum or vinyl, available in a wide range of colors, and known for their slim profile, affordable price point, and dependable light control.
Expanded Detail
The 1-inch slat width means mini blinds stack more compactly than standard blinds, making them a natural fit for smaller windows, doors with glass panels, and multi-window rooms where a narrower look is preferred. Aluminum mini blinds are lightweight and rust-resistant; vinyl options add a degree of moisture tolerance. Both materials are available in dozens of colors — from clean whites and neutrals to bolder tones that treat the blind as a design element rather than a purely functional one.
