Where To Hang A Mirror

Mirrors are usually hung where a wall looks empty. That reasoning ignores the only thing a mirror actually does, which is present a second view of whatever sits opposite it.

A mirror is a window onto the opposite wall

Whatever the mirror faces is what people will see in it, at roughly the same visual weight as the real thing.

A mirror facing a blank hallway wall doubles a blank wall. One facing a window doubles daylight and a view, which is why that placement is the classic advice.

The useful step before hanging is standing where people usually stand and noting what is behind you, since that is the content the mirror will display.

Reflected light is real light

A mirror positioned to catch daylight redirects it into parts of a room the window cannot reach directly, which measurably brightens a dark corner.

The same applies to lamps and candles at night, where a mirror behind a light source spreads it rather than leaving a single bright point.

This is why mirrors work particularly well in interior hallways and small bathrooms, which have little or no natural light of their own.

Height is set by use, not by the wall

A mirror people look into is positioned for eye level of the people using it, which differs between an entry, a bathroom and a dressing area.

A mirror intended as a reflective surface rather than for looking into can sit anywhere, and often works best low or leaning where it catches floor and light.

Hanging every mirror at a standard height treats both cases the same and generally serves neither well.

Size relative to what is below it

A mirror hung above a console, mantel or vanity is read as part of that group, so its width is judged against the piece beneath rather than against the wall.

A mirror noticeably narrower than the furniture below looks undersized, while one matched to roughly the width of the piece settles into place.

Two mirrors facing each other rarely works

Opposing mirrors create a receding sequence of reflections that is visually busy and gives the eye nowhere to settle.

They also reflect movement from both directions, which makes a room feel unsettled in a way people notice without identifying the cause.

Where a second mirror is wanted, placing it on an adjacent wall rather than opposite keeps the light benefit without the corridor effect.
