Decorating with mirrors is the fastest, cheapest way to make a room feel bigger, brighter and more finished. A well-placed mirror bounces daylight into dark corners, doubles a view and adds instant depth to a small space. Below are ten practical ideas you can set up in an afternoon, no renovation or paint required.
Mirrors work because they reflect light and sightlines back into the room, tricking the eye into reading more space than there really is. The trick is placement — reflect something worth looking at, and aim light where you want it. Pair a few of the ideas below and even a boxy rental unit starts to feel open and considered.
1. Face a window to double the daylight
Hang a large mirror on the wall opposite or beside your main window. It catches incoming daylight and throws it deeper into the room, making dim spaces feel sunlit without touching a light switch.
This single move does more than any other on the list. In a north-facing living area it can lift the whole room by mid-morning. Style the surrounding wall with a few pieces from a curated art and wall decor range so the mirror reads as part of a gallery, not an afterthought.
2. Widen a narrow hallway
Long, skinny hallways are the classic problem spot. A tall mirror mounted along one wall visually pushes the passage outwards and stops it feeling like a tunnel.
Lean a full-length mirror against the wall at the far end instead, and you draw the eye forward and add a handy last-look-before-you-leave spot. Anchor the base with a natural-fibre seagrass door mat to ground the corner and add a bit of texture underfoot.
3. Create a faux window in a dark corner
No window in that gloomy corner? Fake one. A large framed mirror positioned where a window would sit reads like an extra opening and pulls borrowed light across the room.
Choose a frame with a bit of depth — timber, rattan or a soft arch shape — so it convincingly mimics a real window. Flank it with tall plants or a slim console to complete the illusion and soften the wall.
4. Layer a mirror behind a shelf display
Set a mirror as the backdrop to open shelving or a sideboard vignette. It reflects your favourite objects from behind, so a small collection of candles, books and ceramics instantly looks fuller and more curated.
This works beautifully in a dining nook or hallway console. Keep the shelf styling restrained and let the reflection do the doubling — a handful of well-chosen pieces from a considered home decor edit reads as twice the display.
5. Build a mirror gallery wall
Instead of one big mirror, cluster several smaller ones in mixed shapes and frames. A grouping of round, arched and rectangular mirrors adds personality and scatters light across a whole wall rather than one spot.
Lay the arrangement out on the floor first to nail the spacing before you hang anything. Mix in a couple of framed prints so the wall feels collected over time rather than bought as a matching set.
6. Reflect a leafy view or feature
Angle a mirror to capture something you actually want to see twice — a green courtyard, a bookshelf, a pendant light or a piece of art. Reflecting a view outdoors pulls the garden inside and blurs the line between the two.
Avoid pointing a mirror straight at clutter, a doorway into the laundry, or a blank wall. The reflection becomes part of your decor, so make sure it's earning its place.
7. Brighten a bedroom without the glare
In bedrooms, position a mirror to bounce daylight without reflecting straight into the bed or catching harsh afternoon sun. A mirror on the wall adjacent to the window is usually the sweet spot — light in, no glare.
Soften the reflection with a bench or armchair dressed in plush, well-filled cushions. Quality inserts like these Australian-made cushion inserts hold their shape and stop styled corners looking flat and tired in the mirror.
8. Go floor-to-ceiling in a small room
In a tight bedroom, study or entry, a leaning full-length mirror creates a floor-to-ceiling line that instantly lifts the perceived height and doubles the floor space. It's the single best trick for a small footprint.
Lean it securely against the wall and, in a household with kids, fix the top to a stud with a safety strap. The effect is generous and hotel-like for very little outlay.
9. Add depth behind a sofa or bedhead
A wide mirror hung above the sofa or bedhead adds architectural depth to the main wall and reflects the light fitting or window opposite. It makes the whole seating or sleeping zone feel more expansive.
Keep the frame in proportion — roughly two-thirds the width of the furniture below it looks balanced. Dress the sofa with a mix of cushion sizes; a plump square cushion insert under a favourite cover fills out the arrangement so the reflection looks styled, not sparse.
10. Use mirrored and reflective accents
You don't need a giant mirror to get the effect. Mirrored trays, metallic vases, glass hurricanes and a shiny lamp base all scatter light in miniature and add a little sparkle to a coffee table or shelf.
Scatter two or three reflective accents around a room to lift it subtly without going full glam. Grouped on a tray, they catch every bit of lamplight and make evenings feel warmer and more considered.
Quick-start tips
- Hang at eye level. Centre most wall mirrors around 150–160cm from the floor so the reflection lands where people look.
- Reflect light, not clutter. Always check what the mirror will show before you fix it to the wall.
- Go bigger than feels safe. One large mirror almost always beats several tiny ones for opening up a room.
- Mind the weight. Use the right wall anchors for the surface and secure tall leaners against tipping.
- Layer with texture. Pair hard, shiny glass with soft cushions, rugs and timber so the space feels warm, not cold.
Frequently asked questions
Where is the best place to hang a mirror to make a room look bigger?
Hang it opposite or beside your main window so it reflects daylight back into the room. This bounces natural light into dark corners and doubles the view, which tricks the eye into reading more space. In narrow rooms, a tall mirror on the longest wall widens the whole area.
How big should a decorative mirror be?
For a feature wall, go as large as the space allows — one big mirror almost always opens a room up more than several small ones. Above furniture, aim for a mirror around two-thirds the width of the sofa, bedhead or console beneath it so the proportions feel balanced rather than lost.
Do mirrors really make a room brighter?
Yes. Mirrors don't create light, but they reflect and redirect it, so a mirror placed across from a window pushes daylight deeper into the room and lifts dim corners. Positioned near a lamp or pendant in the evening, it multiplies that light too, making the whole space feel warmer and more open.
What should a mirror not reflect?
Avoid reflecting clutter, a view into a laundry or bathroom, a blank wall, or harsh direct sun that will glare. Whatever the mirror shows becomes part of your decor, so aim it at something worth seeing twice — a leafy courtyard, a light fitting, artwork or a styled shelf.
