Why Mirrors Can Make a Room Look Bigger
The idea that mirrors can make a room look bigger is rooted in the way light and reflections work. Mirrors don’t physically increase the size of a room, but they can visually expand the space by reflecting light, creating the illusion of depth, and drawing the eye across the room.
Here’s how mirrors work their magic:
Reflecting Light
Mirrors are excellent at reflecting light. When placed opposite a window or light source, they can bounce light around the room, making it feel brighter and more open.
A brighter reflection can make a room feel more open, but the result depends on what the mirror reflects, the light available and the surrounding furniture.
A mirror reflects existing light; it does not remove every dark corner or distribute light evenly by itself. Look at the reflected view from the doorway and seating positions before deciding where to hang it.
Creating Depth and Dimension
Mirrors can also create the illusion of depth. By reflecting parts of the room that aren’t immediately visible, a mirror can make a space feel like it extends beyond its actual size.
This is particularly effective when mirrors are placed on a feature wall or opposite furniture, giving the room a sense of continuity and openness.
Adding Vertical or Horizontal Lines
The size and shape of the mirror can also play a role in how it influences the perception of space.
Full-length mirrors can make a room feel taller by drawing the eye upward, while long, horizontal mirrors can create the illusion of width, making a narrow room feel more expansive.
The right shape can work wonders for shaping the room’s proportions and making it appear larger.
How to Use Mirrors to Make a Room Look Bigger
Now that we understand why mirrors have this effect, let’s explore the best ways to use them in your space to achieve the illusion of a larger room.
Here are a few tips on strategically placing mirrors to maximise their impact.
Place Mirrors Opposite Windows
One of the most effective ways to make a room look bigger is by placing mirrors opposite windows or light sources.
This allows the mirror to reflect the natural light coming in from the window, brightening up the room and making it feel more spacious.
The reflection of outdoor views can also create the illusion of a larger, more open area.
Tip: If you’re placing a mirror near a window, avoid placing it where it will reflect a cluttered area or a distracting view. Ideally, the reflection should enhance the room’s decor and atmosphere.
Use Large Mirrors on Feature Walls
Placing a large mirror on a feature wall can create a striking focal point that expands the visual space.
A full-length mirror or a large rectangular mirror can draw the eye across the room, making the space feel more expansive.
A console or a suitable clear wall can give a large mirror room to make an impact. For positions above furniture, plan secure mounting for the mirror and wall rather than relying on a decorative placement idea alone.
Tip: In smaller rooms, opt for a single large mirror rather than multiple smaller mirrors to avoid overcrowding the space and to create a more cohesive look.
Create the Illusion of Height with Vertical Mirrors
If you want to make a room feel taller, go for vertical mirrors. Full-length mirrors or long, narrow mirrors can make the ceiling appear higher, creating the illusion of more space.
This works particularly well in rooms with lower ceilings, such as basements or attic spaces.
Try a paper outline at the intended position and check the view from the places you use most. A vertical shape can draw the eye upwards, but an awkward reflection at a corner may be more distracting than spacious.
Add Reflective Accents
You don’t have to rely on a single large mirror to create the illusion of space.
Adding smaller, reflective accents such as mirrored furniture, picture frames, or decor items—can help amplify the reflective effect.
These accents can work together to bounce light around the room, giving the entire space a brighter, more open feel.
Tip: Be mindful of how many reflective pieces you add to avoid a cluttered or overwhelming look. Instead, focus on carefully chosen items that enhance the room’s decor.
Use Mirrors to Reflect Artwork or Views
Mirrors can also be used to reflect beautiful artwork or scenic views, making the room feel more connected to the outside world.
By strategically placing mirrors to reflect art or a picturesque outdoor view, you can make the room feel larger and more open.
Tip: This is especially effective in living rooms or dining areas where you may want to highlight the surrounding environment or complement the existing art on the walls.
