To maximize small spaces with mirrors, position large mirrors opposite windows to reflect natural light throughout the room, instantly creating the illusion of doubled space. For narrow hallways, run a continuous mirror along one wall to visually widen the area. In dining areas, mirrored backsplashes create depth perception that extends wall boundaries. Strategically place mirrors to reflect appealing views or focal points rather than blank walls or clutter. For dramatic effect, install floor-to-ceiling mirrors in strategic locations or create mirror gallery walls using varied sizes and frames. Mirrored furniture pieces like side tables or cabinet doors add reflective surfaces without overwhelming the space. Consider leaning oversized mirrors against walls for casual, designer-approved styling that draws the eye upward. Prioritize proper lighting—mirrors can only amplify existing light—by ensuring rooms have adequate natural and artificial illumination to maximize the space-expanding effect.
