How to Decorate With Mirrors: Bounce Light, Fake Square Footage, and Style a Wall

A mirror is the most useful decorating object you own that most people use for nothing but checking their hair. Placed well, it doubles the light in a dim room, makes a small space read twice its size, and works as sculptural art that happens to be functional. Placed badly, it reflects a blank ceiling, a cluttered corner, or -- worst of all -- itself across the room in an endless funhouse loop. This guide is about placement and intent: how to use mirrors to do a specific job, not just fill a wall.

Put a Mirror Where It Reflects Something Worth Seeing

The first rule of decorating with mirrors is that a mirror doubles whatever is in front of it -- so aim it deliberately. The best placements reflect light and beauty; the worst reflect clutter and blank space.

• Across from or beside a window. This is the classic move: a mirror opposite a window bounces daylight deep into the room and gives a second "window" onto the view. Placing it perpendicular (on an adjacent wall) also catches light without staring straight into the glare.
• Reflecting a good feature. Aim it at a chandelier, a piece of art, a plant, or a pretty vignette -- not at a doorway to a messy hall, the back of a TV, or an empty ceiling.
• Never two mirrors facing each other. That creates the infinite-tunnel effect and can feel unsettling. One well-placed mirror per sightline is plenty.

Use Mirrors to Make a Small Room Feel Bigger

Mirrors are the cheapest square footage you can buy. A few reliable tricks: lean a large floor mirror against the wall in a small room to add instant depth and height; hang a mirror at the end of a narrow hallway to stop it feeling like a tunnel; or use a single oversized mirror rather than a scatter of small ones, which reads as more considered and expands the space more convincingly. In a tight dining room or entry, a big mirror on the long wall visually pushes the walls apart.

Get the Size and Height Right

Scale is where mirror arrangements usually go wrong. A few numbers to work from:

• Over furniture, a mirror should span roughly two-thirds to three-quarters of the width of the piece below it (sofa, console, dresser, mantel) -- the same rule as hanging art. A dinky mirror over a wide console looks marooned.
• Hanging height: center the mirror at eye level, about 57-60 inches to the middle for a standalone piece, or leave 4-8 inches of breathing room above the furniture when it hangs over a console or sofa.
• A leaning floor mirror should be tall enough to be useful and grand -- at least chest height, ideally taller -- and anchored to the wall so it cannot tip.

Treat a Mirror as Art -- Frame, Shape, and Grouping

The frame is what makes a mirror decorative rather than utilitarian. Match the frame to your style: a gilded or ornate frame for traditional and art deco rooms, a thin black or brass frame for modern, an arched frameless or rattan-wrapped mirror for organic and coastal looks. You can also arrange several smaller mirrors as a gallery grouping, mix a mirror into an art gallery wall for a reflective break, or cluster an odd number of round mirrors like bubbles. Just keep the grouping reflecting something pleasant, and vary the sizes so it does not look like a showroom display.

Room-by-Room Quick Wins

• Entryway: a mirror over the console is functional (last look on the way out) and bounces light into a typically dark spot.
• Living room: an oversized mirror over the mantel or sofa adds light and grandeur; angle it to catch a window.
• Dining room: a large mirror reflecting the table and a light fixture makes dinners feel more expansive and glamorous.
• Bedroom: a leaning floor mirror in a corner adds function and depth without crowding the walls around the bed.

Common Mistakes

• Reflecting clutter. A mirror advertises whatever is opposite it. Face it toward light and beauty, never toward mess.
• Going too small. An undersized mirror over big furniture looks lost. When in doubt, size up.
• Hanging too high. A mirror tilted up at the ceiling only reflects the ceiling. Keep it at eye level so it does its job.
• Forgetting to anchor. Large and leaning mirrors are heavy and top-heavy -- secure them to studs or the wall for safety.

Preview the Light Before You Hang

Because a mirror's whole value depends on placement and scale -- what it reflects and how big it reads -- it helps to see the effect before you put holes in the wall. Upload a photo of your room and try different mirror sizes, shapes, and placements with Room Reveal to see how each one bounces light and opens up the space.
