What a Mirror Actually Does
A mirror does three things simultaneously: it reflects light, making a room feel brighter; it creates the illusion of depth, making a space feel larger; and it functions as a decorative object in its own right. No other single element in interior design achieves all three at once. This is why mirrors are worth spending money on and thinking carefully about — they're not just practical objects, they're one of the most powerful tools a room has.
The Entrance Hall: Where a Mirror Earns Its Keep
The entrance hall or hallway is the first room anyone experiences when they enter your home — and mirrors work harder here than anywhere else. A large mirror in a hallway reflects light from windows or from the room beyond, immediately making the space feel less enclosed. At the same time, it gives people a chance to check their appearance before leaving — the most practical possible function for a mirror in the home.
In a narrow hallway, a tall vertical mirror placed on the longest wall creates an illusion of width. In a square hallway, a circular or oval mirror adds softness and breaks the boxiness of the space.
In the Living Room
Above the fireplace or above a sideboard or console table, a large mirror anchors the room's main display wall and doubles the perceived height of the space. Position it so that it reflects something beautiful — a window, a lamp, a plant, an arrangement of objects on the surface below it. A mirror that reflects clutter or a blank wall wastes its potential.
In a living room without a fireplace, a leaned mirror — propped against the wall rather than hung — creates a more relaxed, layered feeling and allows for easy repositioning. A large leaned mirror in a corner opposite a window maximises the room's natural light.
In the Dining Room
A mirror in the dining room reflects candlelight and lamplight during evening meals, creating an atmosphere that's genuinely magical. Position it so that it catches the light from candles on the table or a lamp on the sideboard. The warm reflection of flame in a large mirror is one of the most atmospheric things a dining room can have.
Mirror Shapes and Frames
The shape and frame of a mirror are as important as its placement. Some guidelines:
- Round and oval mirrors — add softness to rooms dominated by straight lines and rectangular furniture. Particularly good in hallways, bathrooms and as accent pieces in living rooms.
- Rectangular mirrors — more formal and structural. Good above fireplaces and sideboards where they create a sense of order.
- Arched mirrors — combine the visual interest of an arch with the practicality of a rectangular form. Particularly versatile and currently very popular.
- Sunburst and decorative frames — make more of a statement. Best treated as the focal point of a wall rather than part of a larger arrangement.
For frame materials: gold and brass work in classic, maximalist and Japandi spaces; natural wood in Scandinavian and organic interiors; black metal in industrial and contemporary rooms; plaster and white finishes in minimal and Mediterranean spaces.
Grouping Mirrors
A single large mirror makes a statement. A gallery wall of smaller mirrors creates texture and visual interest. If you're grouping multiple mirrors, vary the shapes and frames while keeping a unifying element — similar metal finish, similar scale, a shared colour in the frames. The arrangement should look collected rather than coordinated.
The One Rule
Whatever you do with a mirror, be intentional about what it reflects. Walk to where the mirror will hang, look at the reflection from that position, and ask: is this the best view the room has to offer? If not, adjust the position or the angle until it is.
