Mirror: artwork or furniture by size

According to its size, a mirror plays two completely different roles.

Small mirror (up to 80 cm). Functions as a decorative object, like a frame or artwork. Primarily aesthetic rather than spatial function.

Large mirror (1.20 m+). Functions as an architectural element that modifies the room's perception. Visually enlarges, doubles surfaces, reflects light. See also rule 05.1 on the mirror facing the window.

In a small or medium room, invest in one large mirror rather than multiplying small ones. The effect on space is incomparable.

The small mirror. On an entrance console (60-80 cm, hung 15-20 cm above the top of the unit). In a bathroom (above the basin, adapted to the sink). On a gallery wall interspersed between frames.

The large mirror. Five strategies: facing the window (see rule 05.1), vertical from floor to ceiling leaned against a wall (see rule 05.10), horizontal above a sofa or fireplace (1.20-1.80 m width), floor-leaning psyché in a bedroom, entire wall mirror in a narrow entrance or bathroom.

Choosing the frame. Slim matt black metal or brass: contemporary effect. Thick wood (oak, walnut): warmer and Scandinavian. Gilded or patinated: classical, more formal. Frameless: ultra contemporary, almost architectural.

In small interiors. One large, well-placed mirror is the most cost-effective investment for visually enlarging the room. Prefer one large mirror well positioned over several small ones scattered around.

Joseph Dirand works almost exclusively with floor-to-ceiling large mirrors, sometimes in multiple vertical panels. Ultra architectural effect.

Pierre Yovanovitch integrates flush mirrors into walls (frameless, built-in), creating forced perspective effects. Reserved for bespoke projects.
