Hang a large mirror where the reflection improves the room and the wall can support it properly. Above a console, on a living-room feature wall or over a bathroom vanity are useful starting points. Check what appears in the glass from the positions where you sit, stand or enter the room.
A large mirror makes a stronger feature when it reflects something you enjoy: daylight, a tidy part of the room or a favourite detail. Size alone does not create a better layout.
Above furniture: judge the whole composition
Mark the full mirror outline above the console or sofa. Leave a gap that looks deliberate and allows for any lamps or objects below it. A fixed rule such as two-thirds of the furniture width is only a design starting point, not a requirement.
Check the reflected view from the main seating position. A beautiful frame can still feel awkward if the glass mainly shows a ceiling fitting or a cluttered shelf.
In an entryway: make the reflection useful
Place the mirror where a quick appearance check is comfortable without blocking the door or a busy walking route. For a full-body view, test the top and bottom edges from the intended standing position; centring the whole mirror at eye level is not a universal solution.

120 × 60 cm long oval bevelled mirror — £99. An elongated outline for a wall where you want a softer shape. Compare the dimensions and intended mounting orientation with the reflection you need.
On a living-room wall: choose one focal point

63.5 × 83.1 cm decorative asymmetric mirror — £170. An expressive outline for a feature wall. Above a working fireplace, check the appliance’s clearances and the mirror’s suitability for heat exposure before deciding on the location.
An extra-large arched Venetian-style mirror gives a different decorative emphasis. Use its actual dimensions and weight when planning support, rather than copying the position of a smaller mirror.
Above a vanity: balance width with daily use

140 × 70 cm extra-large dual-light mirror — £299. A broad illuminated reflection for a generous vanity. Front light supports the viewing area and a rear glow adds atmosphere to the wall.

Check the basin positions, wall lights, taps and doors together. For a shared vanity, make sure both users have a comfortable view rather than aligning only with the middle of the furniture.
Test the light before committing
A mirror opposite a window can reflect daylight into the room, but it can also reflect glare. Check it at the times the room is normally used. Keep the reflection of exposed bulbs or bright sunlight out of the main viewing position where possible.
Above a bed is usually a decorative rather than practical grooming position. A large or heavy mirror needs a secure, appropriate installation wherever it is placed; do not choose the location only because there is an empty wall.
Plan the support at the same time
Use the mounting arrangement specified for the mirror and fixings appropriate to the wall structure and load. Do not assume adhesive strips or a picture hook are suitable for a large panel. Arrange help for lifting and professional installation where the wall or load needs assessment.
For illuminated bathroom models, our installation guide, electrical planning guide and mirror hanging guide help organise the work. The best position brings together a useful reflection, an attractive view and a mounting plan that suits the real product.
