Mirrors are the quiet overachievers of home decor. The right one makes a room feel bigger, throws daylight into dark corners and fills a bare wall — all without a coat of paint or a single power tool. Here are seven simple ways to decorate with mirrors, whatever your space.
1. Lean a big arched mirror to add height

A large arched floor mirror leaned against the wall draws the eye upward and instantly makes a room feel taller. The soft arch is gentler than a hard rectangle, and because it sits on the floor, there's no drilling — just lean and go.
2. Place a mirror opposite a window

This is the oldest trick there is, and it still works. A mirror hung or leaned opposite a window catches the daylight and bounces it back into the room. A slim, full-length frame is the easiest way to brighten a dark corner without adding a lamp.
3. Anchor an entryway with a mirror and bench

A rectangular mirror above a bench turns a bare hallway into a real entryway — somewhere to check your look on the way out, drop your keys and pull a little light into an often windowless space.
4. Choose a freestanding mirror you can move

A freestanding mirror on a slim stand needs no wall fixings at all. Lean it, angle it, carry it from the bedroom to the hall whenever the mood changes — ideal for renters and rearrangers.
5. Soften a hard corner with an oval

Walls, shelves and frames add up to a lot of straight lines. A rounded oval mirror breaks them up and brings a softer, calmer shape to a busy wall.
6. Warm up a cool wall with a wood frame

An all-white wall can feel a little cold. A warm walnut-framed mirror above a console adds a natural, tactile edge and stops the space from feeling clinical — glass with a bit of warmth around it.
7. Layer in a small tabletop mirror

You don't need a statement piece to get the effect. A small round mirror layered into a dresser or console vignette adds a reflective glint and a little everyday function to your styling.
How to decorate with mirrors: FAQ
Where should you place a mirror in a living room? Opposite or next to a window so it bounces daylight, or on the longest empty wall to open the space up. Avoid hanging it facing clutter — a mirror doubles whatever it reflects.
Do mirrors really make a room look bigger? Yes. Mirrors add visual depth and reflect light, so a well-placed one makes a small or dark room feel noticeably larger and brighter — one of the cheapest ways to open up a space.
How do you hang a heavy mirror safely? Find the wall studs and use heavy-duty D-rings or a French cleat rated above the mirror's weight; on plasterboard with no stud, use proper anchors, never a single nail. Prefer no drilling? A large floor or freestanding mirror leans against the wall with zero fixings.
Can you have two mirrors in one room? You can — just avoid placing them directly facing each other. Use one as the statement piece and keep the second smaller, so the room feels layered rather than busy.
What shape of mirror is best? Arched and oval mirrors feel soft and current; rectangular mirrors feel classic and structured. Choose the shape that contrasts with the lines already in the room.
How big should a mirror be? Over furniture, aim for a mirror about two-thirds the width of the piece below it. For impact, a full-length or floor mirror is hard to beat.
The takeaway
A mirror is the cheapest way to add light, depth and a finished feel to a room. Lean a big one for height, face a window to borrow daylight, and pick a shape that softens the space. One mirror, a whole new room.
