A mirror is the hardest-working piece in any room: it bounces daylight into gloomy corners, doubles the sense of space, and finishes a wall the way a full stop finishes a sentence. Yet most of us buy one that is too small, hang it too high, or point it at the wrong thing entirely. This guide walks you through sizing, shape, placement and finish for every room in the home, with real measurements in centimetres so you can order once and hang with confidence.
1. Why a mirror is more than decoration
Think of a mirror as free architecture. Where a window brings in daylight, a well-placed mirror redistributes it, softening shadows and lifting the whole mood of a room without a single watt of electricity. That is why interior designers reach for one first when a space feels dark, boxy or flat.
A mirror also does jobs no other piece can. It gives a hallway a moment for a last-minute check before you leave, turns a plain stretch of wall into a focal point, and, crucially, tricks the eye into reading a small room as larger than it is. Reflect a bookcase, a fireplace or a leafy corner of greenery and you effectively gain a second version of it for free.
The mistake is treating a mirror as an afterthought once the sofa and the rug are in. Decide early what you want it to do — add light, add depth, or simply look beautiful — because that single decision drives the size, shape and position that follow.
2. Getting the size right
Undersizing is the most common mirror mistake by a wide margin. A dinner-plate-sized round adrift on a big wall looks lost. As a rule of thumb, a feature mirror should fill roughly two-thirds to three-quarters of the width of the furniture or wall space beneath it. Over a 180cm sideboard, that means a mirror around 120–135cm wide; over a 120cm console, aim for 80–90cm.
Scale the mirror to the wall, not just the furniture. On a tall wall with high ceilings, a portrait-orientation or full-length mirror draws the eye upward and emphasises the height. On a long, low wall, a wide landscape mirror echoes the horizontal and calms the room. Leave a comfortable margin of at least 15–20cm of bare wall around a mirror so it can breathe rather than crowding the corners.
If you are shopping for a full-length mirror to dress in front of, 120cm tall by 40cm wide is the practical minimum to see a head-to-toe reflection, with 150cm x 50cm giving a more generous view. For a bathroom mirror above a basin, match it roughly to the width of the vanity or a touch narrower, and never wider than the unit itself.
3. Choosing a shape and frame
Shape sets the tone before anyone notices the finish. Rectangular and square mirrors feel structured, classic and calm; they sit naturally above console tables, mantelpieces and sideboards. Round and oval mirrors soften a scheme full of straight lines — a circular mirror over a boxy chest of drawers or a rectangular basin introduces a welcome curve.
Arched and arch-top mirrors have become a modern favourite because they nod to a window or doorway, adding architectural interest to a flat wall. Sunburst and organic-edged mirrors are statement pieces: brilliant as the single focal point in a hallway or above a fireplace, but best used sparingly so they do not compete with everything else.
The frame does as much work as the glass. A slim black or brushed-brass frame reads contemporary; ornate gilt or distressed timber leans traditional; frameless or bevelled-edge mirrors all but disappear, which is exactly what you want when the goal is pure light and space rather than decoration.
4. Placement and hanging height
Height is where good mirrors go wrong. The centre of a mirror should sit at average eye level, roughly 145–150cm from the floor to the middle of the glass. Above furniture, leave about 15–20cm between the top of the sideboard or console and the bottom of the frame so the two read as a pair rather than one floating above the other.
Position matters as much as height. The golden rule is to hang a mirror where it reflects something worth seeing — a window, a chandelier, a piece of wall art or an inviting view — and never where it merely doubles a blank wall, a radiator or the underside of the stairs. Before you commit, stand where people usually sit or enter and check what the glass actually shows.
Leaning a large mirror against the wall is a relaxed, on-trend alternative to hanging, ideal in bedrooms and dressing areas. If you go this route, always secure the top to the wall with a safety strap or bracket — a floor-standing mirror of 150cm or more is heavy enough to be a genuine hazard if it tips.
5. Using mirrors to bounce light
The single most effective placement for light is opposite or adjacent to a window. A mirror hung on the wall perpendicular to a window catches the daylight and throws it deep into the room; placed directly opposite, it can double the apparent number of windows and dramatically brighten a north-facing space.
- Dark hallway: a tall mirror on the wall facing the front door or a side window instantly lifts a windowless corridor.
- North-facing living room: a large landscape mirror above the sofa or fireplace spreads what little light there is across the whole room.
- Small kitchen or dining nook: a mirror behind a shelf or console reflects task lighting and makes the space feel open.
- Snug or reading corner: place a mirror to catch a lamp so one light does the work of two.
Be deliberate about what the mirror reflects at night as well as by day. A mirror that beautifully bounces sunshine can, after dark, simply reflect a bare bulb or a blank corner. Pair it with a warm table or floor lamp nearby and the reflection stays inviting from morning to midnight.
6. Room-by-room guide
Every room asks something slightly different of a mirror. Use the table below as a quick starting point for size and orientation, then adjust to your own walls.
| Room | Typical size | Best placement |
|---|---|---|
| Hallway | 60–90cm wide, portrait or round | Opposite the door or above a console |
| Living room | 100–140cm wide, landscape | Above the fireplace or sideboard |
| Bedroom | 120–170cm tall, full-length | Leaning, or beside the wardrobe |
| Dining room | 90–150cm wide | Angled to catch a window or candlelight |
| Bathroom | Match vanity width | Centred over the basin |
In the bedroom, a full-length mirror is close to essential for dressing; pair it with a dressing table mirror for detail work. In the hallway, a mirror above a slim console creates a proper welcome and a place for keys. In the bathroom, look for a mirror rated for damp conditions, and consider one with integrated LED lighting or a demister pad if the room steams up.
Living rooms give you the most freedom. Over a mantel or a media unit, a wide mirror anchors the wall; on a bare stretch beside the window, a large leaning mirror adds instant depth. If you are furnishing a compact space, our small living room ideas guide shows how a single well-placed mirror can make a modest room feel a size bigger.
7. Matching the style to your scheme
A mirror should feel like it belongs to the room, not like it wandered in from a different house. Take your cue from the finishes already present — the leg of a coffee table, the handles on a chest of drawers, the metal of your light fittings — and echo one of them in the frame.
- Modern and minimal: slim frames in black, chrome or brushed brass, or a clean frameless bevelled edge.
- Classic and country: painted or limed-timber frames, gentle arches and soft, aged finishes.
- Glamorous and warm: gold or antique-brass frames, sunburst designs and subtle antiqued glass.
- Industrial: raw metal, riveted or window-pane multi-panel mirrors for a workshop feel.
You do not need to match metals across a room exactly, but keep the palette to two finishes at most so the scheme stays coherent. If your accessories already lean warm, a brass-framed mirror pulls the look together; if the room is cool and calm, black or nickel keeps it crisp. When in doubt, a simple frame in a colour drawn from the woodwork is the safest bet and the one you will tire of the slowest.
8. Hanging safely and securely
Mirrors are heavier than they look — a 100cm framed mirror can weigh 10–15kg — so fixings are not the place to economise. Always fix into something solid. Into masonry, use a wall plug and screw rated well above the mirror’s weight; into a stud partition, screw directly into the timber stud, and if the fixing points do not line up with a stud, use heavy-duty toggle or spring-cavity fixings rather than a plasterboard plug alone.
- Weigh the mirror or check the product listing so you can buy the correct fixings.
- Use a stud detector to find timber and, just as importantly, to avoid pipes and cables.
- For anything over about 10kg, use two fixing points spread apart rather than a single hook, and check the mirror sits level with a spirit level.
- Leaning a large mirror? Anti-tip straps take two minutes to fit and are essential in any home with children or pets.
Finally, give the fixing a firm downward tug before you trust it, and re-check it a week later once everything has settled. A few minutes of care at the start is what keeps a beautiful mirror on the wall rather than on the floor.

Frequently asked questions
What size mirror should I hang above a console table?
Aim for a mirror that spans roughly two-thirds to three-quarters of the console’s width. Over a 120cm console that means 80–90cm wide, leaving a balanced margin either side. Hang it with about 15–20cm between the top of the console and the bottom of the frame.
How high should a mirror be hung?
The centre of the glass should sit at eye level, around 145–150cm from the floor. Above furniture, prioritise leaving a 15–20cm gap above the piece so the two read as a pair, adjusting the overall height to suit the tallest members of the household.
Where should I place a mirror to make a room look bigger?
Hang it opposite or perpendicular to a window so it catches and redistributes daylight. Reflecting a window, a view or a light source doubles the sense of space, while pointing a mirror at a blank wall or radiator does nothing for the room.
Round or rectangular — which mirror shape is best?
It depends on the room’s lines. Rectangular mirrors feel structured and suit mantels, consoles and sideboards, while round and oval mirrors soften a space full of straight edges. A curved mirror over a boxy chest of drawers is a classic, flattering pairing.
What size full-length mirror do I need?
For a head-to-toe reflection, 120cm tall by 40cm wide is the practical minimum, with 150cm x 50cm giving a more generous view. Stand about a metre back when you check it, and secure any leaning full-length mirror to the wall with an anti-tip strap.
Can I use any mirror in a bathroom?
Choose a mirror suitable for humid conditions, ideally with a sealed backing to resist desilvering. Match it roughly to the width of the basin unit, and consider one with integrated LED lighting or a demister pad if the room steams up quickly after a shower.
How do I hang a heavy mirror securely?
Fix into masonry with wall plugs and screws rated above the mirror’s weight, or screw directly into timber studs in a partition wall. For anything over about 10kg use two spread fixing points, check it with a spirit level, and avoid relying on a single plasterboard plug.
How do I stop mirror glass developing black spots?
Those black edges are desilvering, usually caused by moisture seeping behind the glass. Clean with a microfibre cloth sprayed lightly with water or diluted vinegar rather than spraying the mirror directly, and keep liquid away from the frame edges and backing.
