Mirror Buying Guide UK: How to Choose the Right Mirror for Every Room
A mirror is one of the few pieces of decor that changes how a whole room feels — bounce light into a dark hallway, make a small bedroom breathe, or turn a bare wall into a focal point. But get the size, shape or placement wrong and it can just as easily make a room feel off. Here's how to choose a mirror that actually works for the space you're putting it in.
The quick answer
For most rooms, pick a mirror that's roughly two-thirds the width of whatever it's hanging above (a console table, a fireplace, a sofa), and hang it so its centre sits at eye level — about 150–160cm from the floor. Use a full-length or leaning floor mirror in bedrooms and hallways for outfit checks, a round or softly-shaped mirror to soften a room full of hard edges, and an illuminated mirror with anti-fog glass in bathrooms where a normal mirror keeps steaming up. Everything below explains the reasoning and shows real examples at each price point.
Mirror types, explained
Not every mirror does the same job, so start with what you actually need it to do:
Wall mirrors are the most flexible option — decorative pieces that hang flat against a wall to add light and style without taking up floor space. They range from simple frameless designs to statement pieces like the 170cm cast iron black wall mirror (£171.63), which works as a piece of wall art in its own right.
Full-length and leaning mirrors stand on the floor or lean against a wall and show your whole outfit, not just head and shoulders. They're the standard choice for bedrooms and hallways. The arched full-length mirror with a black or gold aluminium frame comes in three sizes from £150.40 and can be wall-mounted, freestanding, or leaned, so it works in rooms where you're not ready to commit to drilling holes.
Vanity and dressing table mirrors are smaller, sit on a surface, and are built for close-up tasks like makeup or grooming — the lighted tri-fold vanity mirror (£44.86) adds LED lighting so you're not doing your makeup by guesswork.
Illuminated and bathroom mirrors combine a mirror with built-in lighting, and often a demister or storage cabinet, to deal with bathroom-specific problems: steam, limited wall space, and the need for genuinely good light near a sink. More on these below, since they have their own set of things to check before buying.
What size mirror do you actually need?
The rule interior designers use most often: a mirror should be about two-thirds the width of the furniture or wall feature it's paired with. Above a console table that's 90cm wide, that means a mirror around 55–65cm wide. Above a fireplace, take two-thirds of the mantel's width. It's a starting point, not a law — a slightly larger mirror can make a small room feel more open, while going much bigger than that risks the mirror overwhelming the piece it's meant to complement.
| Room / spot | Typical mirror size | Good format |
|---|---|---|
| Hallway console or entryway | 40–70cm wide | Round or wall mirror |
| Above a fireplace or sofa | 70–120cm wide | Statement wall mirror |
| Bedroom (outfit checks) | 40–80cm wide, 120cm+ tall | Full-length or leaning |
| Bathroom, single sink | 50–80cm wide | Illuminated wall mirror |
| Dressing table | 30–50cm wide | Vanity or tri-fold |
Where to hang or place it
Height matters more than most people expect. Centre a wall mirror at eye level for an average adult — roughly 150–160cm from the floor to the middle of the mirror — rather than centring it on the wall itself, which often ends up too high. In a hallway, position a mirror where it catches natural light from a nearby window or door and throws it further into the space, rather than facing a blank wall. In a living room, a mirror opposite or beside a window does the same job on a larger scale. In a bedroom, a full-length mirror works best with enough floor clearance in front of it to actually step back and see your whole outfit — a corner near the wardrobe is usually more useful than one wedged behind a door.
Frame materials and styles
The frame does most of the work in setting the mood:
Metal frames — cast iron, aluminium, brushed steel — read as modern or industrial, and hold up well in busier rooms since they're harder to chip than wood. The 170cm cast iron mirror above and the 63cm rusty wall mirror (£58.30) both lean into this, with a raw, aged finish that suits hallways and outdoor-adjacent spaces like porches.
Reclaimed and solid wood frames bring warmth and texture, and suit coastal, rustic or farmhouse-style rooms — the coastal large mirror frame (£228.60), made from reclaimed solid wood with natural colour variation, is built for this look specifically.
Clean, minimal designs, like the 85cm modern mirror (£111.55), work when you want the mirror itself to stay understated rather than compete with everything else on the wall, which suits smaller or already busy rooms.
Sculptural metal pieces such as the HOMCOM decorative wall sculpture mirror (£67.73) sit somewhere between mirror and wall art, and work best as a single feature rather than paired with other large pieces nearby.
LED and illuminated mirrors: what to actually check
This is where most buyers get caught out, because "illuminated mirror" covers a wide range of features and not every option includes all of them. Before buying one, check for:
Colour temperature control. A mirror that switches between warm white, cool white and daylight settings is more useful than one fixed at a single tone, since makeup and grooming look different under each. The kleankin dimmable bathroom mirror (£102.02) offers three colour settings plus dimming via touch control.
Anti-fog or demister function. A heated demister pad keeps the glass clear after a hot shower, which matters more in bathrooms without great ventilation. The same kleankin model includes a defogging film for this reason.
Storage built in. If bathroom space is tight, a mirror cabinet does double duty — the kleankin LED illuminated mirror cabinet (£88.92) and the wall-mounted mirror cabinet with storage shelf (£39.28) both combine lighting or mirror space with shelving, so you're not adding a separate cabinet on top.
Power source. Check whether the mirror is USB-powered, battery-powered or needs a hardwired connection, since this affects where in the bathroom it can realistically go.

Caring for your mirror
Clean glass with a microfibre cloth and a light glass cleaner or a vinegar-water mix, wiping in straight lines rather than circles to avoid streaking. Avoid spraying cleaner directly onto the mirror if it has a wood or metal frame — spray the cloth instead, since moisture can warp wood or dull a metal finish over time. For illuminated mirrors, switch off and unplug before cleaning near any touch controls or wiring.
FAQ
What size mirror should I put above a console table?
Aim for roughly two-thirds the width of the table itself. A 90cm-wide console generally pairs well with a mirror between 55–65cm wide.
How high should a wall mirror be hung?
Centre it at eye level for an average adult, which usually works out to around 150–160cm from the floor to the middle of the mirror, rather than centring it on the wall.
Can a mirror really make a small room look bigger?
Yes, when it reflects a light source such as a window — this doubles the sense of natural light in the room. A mirror facing a blank wall doesn't create the same effect.
Do illuminated bathroom mirrors need to be hardwired?
Not always — some run on USB power or batteries, which makes them easier to fit without an electrician. Check the power source before buying if you want to avoid rewiring.
What's the difference between a demister and anti-fog coating?
A demister is a heated pad behind the glass that clears condensation with warmth; an anti-fog coating is a film on the glass surface that stops moisture beading in the first place. Some mirrors, like the kleankin dimmable bathroom mirror above, include both.
Should a full-length mirror be mounted or freestanding?
Either works — freestanding and leaning mirrors are easier to move between rooms or take with you if you rent, while wall-mounted versions free up floor space in smaller rooms.
