Small homes are a reality for a growing number of Australians. Whether it is an apartment in inner Sydney or Melbourne, a compact terrace in Brisbane, or a modest freestanding home in a regional area, living in a space that feels tight is a common experience. The architecture is what it is. The square metreage cannot be changed. But the way a space is perceived - how open it feels, how much depth it appears to have, how light moves through it - can be influenced considerably by the objects placed within it.
Mirrors are one of the most reliable tools for creating that perception of additional space. Interior designers have used them for this purpose for a long time, and the principle behind it is straightforward. A mirror reflects the space in front of it. That reflection doubles the apparent visual depth of the room at that point. Done well, it can make a room that is tight and closed feel noticeably more open and airy.
Atfind a mirror style for your space, we stock a wide range of wall mirrors suited to different rooms, aesthetics, and spatial challenges across Australian homes. This guide covers the practical side of using mirrors to make small spaces feel larger - where to put them, what size to choose, and which types work best for specific rooms.
The Visual Principle Behind Mirrors and Space
Understanding why mirrors create the illusion of more space helps you use them more effectively.
When you stand in a room and look at a mirror, your eye reads the reflected image as extending beyond the surface of the mirror into the wall. The reflection appears to be a continuation of the room rather than a two-dimensional copy of it. That visual cue creates the impression of depth that is not physically there.
This effect is strongest when the mirror reflects something meaningful - another part of the room, a window, a light source, or an interesting architectural feature. A mirror reflecting a blank wall behind the viewer creates depth but less visual interest. A mirror reflecting a window or a well-lit part of the room creates both depth and brightness, which amplifies the sense of openness considerably.
Light is the key variable that makes mirrors effective beyond simple reflection. A room that is dark and closed-in will not open up significantly with a mirror. A room with some natural light, where the mirror is positioned to catch and reflect that light deeper into the space, will feel measurably different with a well-placed mirror than without one.
Size Matters More Than Most People Expect
The single most common mistake people make when using mirrors to expand space is choosing one that is too small. A small mirror on a large wall creates a decorative accent. A large mirror on the same wall creates the illusion of a doorway or window into another space. The difference in perceived room size between the two is significant.
For mirrors intended to make a room feel larger, the general principle is to go as large as the wall and budget allow. A mirror that covers a substantial portion of a wall - not crowding the edges, but occupying a generous section of the available surface - does the spatial work far more effectively than a modest-sized piece.
This is particularly relevant in small rooms like hallways, compact living areas, and narrow bedrooms. In these spaces, a large mirror on the primary wall can visually double the perceived width or depth of the room in a way that a smaller piece simply cannot.
In a bedroom, a large frameless or slim-framed wall mirror - perhaps 90cm to 120cm in one dimension - can transform the spatial quality of the room. In a hallway, a tall mirror positioned to reflect the length of the corridor amplifies the depth. In a living room, a large mirror on a wall opposite a window effectively brings the window's light and view into a second dimension of the space.
Placement: Where You Put It Is as Important as What You Choose
Mirror placement is where the spatial principle is either applied well or wasted. The most effective placements share a common logic: the mirror reflects something that makes the room feel larger, brighter, or more connected.
Opposite a window is the most reliably effective placement for any mirror in any room. The mirror catches the natural light coming through the window and reflects it into the space, dramatically increasing the perceived brightness of the room. The reflection of the window itself creates the visual impression of a second opening in the room - a second source of light and space. In a small Australian apartment where natural light is limited, this placement alone can transform a room's feel.
At the end of a hallway is a classic placement for good reason. A narrow hallway feels oppressive in part because it offers no visual depth - you see the end wall and nothing beyond it. A large mirror at the end of the hallway pushes that boundary back visually and makes the corridor feel twice as long. It also reflects light from the other end of the hallway, brightening what is often the darkest part of the space.
On a side wall in a narrow room creates the impression of width. A room that is noticeably longer than it is wide can feel cramped. A large mirror on one of the long walls reflects the opposite wall and the space between them, making the room appear wider than it is.
Above a piece of furniture - a sofa, a console table, a sideboard - anchors the mirror to the composition of the room while still providing the spatial benefit. The furniture below the mirror creates a visual base for the piece, and the mirror above it extends the eye upward and into the reflected space.
Frame Style and Its Effect on Perceived Space
Frame choice affects how much the mirror contributes to a sense of spaciousness. Heavily framed mirrors - thick, ornate, or deeply profiled frames - draw attention to themselves as decorative objects. They add visual weight to the wall and, by extension, to the room. In a small space where you want the mirror to work spatially rather than decoratively, this extra weight can work against the illusion.
Slim frames and frameless mirrors are generally the better choice for small-space applications. They allow the eye to move directly from the room to the reflection without being interrupted by a prominent border. The transition feels more seamless, which strengthens the illusion of extended space.
That said, the right frame can also enhance the spatial effect in specific contexts. A frame in a light, neutral finish - white, soft grey, or brushed silver - recedes against a light-coloured wall and keeps the mirror visually unobtrusive. A mirror with a thin dark frame on a light wall creates a clean, defined border that reads as a considered design choice without adding significant visual weight.
At LED Mirror World, ourexplore mirrors by function and style includes a wide selection of sizes, shapes, and frame styles suited to different spatial applications across Australian homes. Whether you are looking for a large frameless piece for a hallway or a slim-framed option for a bedroom, the range covers the formats most relevant to small-space decorating.
LED-Lit Mirrors: Doubling the Spatial Effect
A standard mirror creates space through reflection. An LED-lit mirror creates space through both reflection and additional light, which compounds the spatial effect meaningfully.
In a small room where ambient light is limited, an LED-lit mirror does two things simultaneously. It reflects the existing space, adding visual depth. And it introduces additional light into the room, which independently makes the space feel more open, cleaner, and less enclosed. A room that is both visually deeper and brighter will feel more spacious than a room that has gained depth without the brightness to support it.
LED bathroom mirrors are a practical starting point for this principle. A bathroom that feels small and dark - a very common configuration in Australian apartments and older homes - can feel meaningfully different with a well-sized LED mirror that reflects the room while also providing illumination that the overhead lighting alone cannot achieve.
Our post on how to incorporate mirrors to make small bathrooms appear larger goes into specific detail on bathroom applications, which is one of the most common and most rewarding rooms in a small Australian home to address with a mirror.
Room-by-Room Applications
Different rooms in a small home present different spatial challenges, and mirror placement can be tailored accordingly.
Living room: A large mirror on the wall opposite the main window reflects light and the living space back into the room. Positioned above a console or sideboard, it also gives the room a clear visual anchor without taking up floor space.
Bedroom: A full-length or near-full-length mirror on a wardrobe wall or side wall increases the sense of width and reflects light from windows. It also serves a functional purpose for dressing - practical and spatial benefit combined.
Hallway: A tall mirror at the end of the corridor is the most effective single placement for creating depth. It also serves the practical use that most hallways require - checking your appearance before leaving the house.
Dining area: A large mirror on a wall adjacent to the dining table reflects the table, the people around it, and any pendant lighting above. It makes the dining area feel larger and, in the evening, amplifies the warmth of the ambient light.
Home office: A mirror on a side wall of a small home office reflects light and creates visual depth without interfering with the desk-facing wall where you work.
Thecompare mirror choices before buying is a versatile option that works beyond the bathroom - its clean, frameless profile suits living rooms, bedrooms, and hallways equally well. The bevelled edge adds a subtle decorative element without introducing visual weight that would work against the spatial objective.
For a hallway or bedroom application where a larger, more impactful piece is the goal, thebrowse bathroom mirrors by feature creates a strong visual statement while still reflecting a generous portion of the space around it. The arched top adds an architectural quality that suits taller ceilings and wider walls.
Our post on how to use mirrors to create the illusion of space in small rooms covers additional placement strategies and practical examples that are directly relevant to the challenges of a compact Australian home.
Practical Notes for Renters
A significant proportion of Australians in smaller homes are renters, and rental properties often come with restrictions on drilling into walls. This does not eliminate the option of using mirrors for space - it just shifts the approach.
Leaning a large mirror against a wall is an effective and installation-free alternative to wall mounting. A large mirror leaned against a hallway or bedroom wall creates much of the same spatial illusion as a mounted mirror, with the added practical benefit of being easy to reposition. For renters, this approach also means the mirror travels with you when you move.
Large format mirrors suited to leaning against a wall are available in the LED Mirror World range, and they represent one of the more flexible ways to apply the spatial benefits of a large mirror in a rental context.
A Final Note on Choosing Well
The mirrors that work hardest in a small space are the ones chosen with the room in mind rather than selected independently of it. Size, placement, frame style, and whether the mirror introduces additional light are all decisions that affect how well the mirror serves the spatial goal.
Thearched mirror ideas for modern bathrooms is a strong option for entryways and compact spaces where a tall, frameless piece reads as clean and unobtrusive while still reflecting a generous vertical section of the room. Its oval format avoids the hard corners that can feel imposing in tight spaces.

Frequently Asked Questions
Do mirrors actually make a room look bigger?
Yes, in a practical and visual sense. A mirror reflects the space in front of it, creating the impression of additional depth beyond the wall surface. When positioned to reflect natural light or another part of the room, this effect is amplified and the room genuinely appears more open and spacious. The effect is stronger with larger mirrors and with strategic placement relative to windows and light sources.
Where should I place a mirror to make a room look bigger?
The most effective placement is opposite a window, where the mirror reflects natural light and creates the visual impression of a second window in the room. Other strong placements include the end of a hallway to extend visual depth, and on the side wall of a narrow room to create the impression of additional width. Avoid placing mirrors where they reflect blank walls or cluttered surfaces, as this reduces the spatial benefit.
What size mirror is best for making a small room look larger?
Larger mirrors create a stronger spatial illusion than smaller ones. In a small room, a mirror that covers a generous portion of a wall - allowing clear space around the edges but occupying a meaningful section of the surface - works considerably harder than a small decorative piece. As a general principle, when using a mirror specifically for spatial effect, choose the largest size that fits proportionately within the available wall space.
Do framed or frameless mirrors work better for small spaces?
Frameless mirrors and slim-framed mirrors tend to work better for spatial applications because they allow the eye to move seamlessly from the room to the reflection without being interrupted by a prominent border. Thick or ornate frames add visual weight to the room, which can work against the illusion of spaciousness. That said, a slim frame in a neutral or light finish can work well if it complements the room's palette without drawing attention to itself.
Can LED-lit mirrors help make a room feel bigger?
Yes. An LED-lit mirror creates space through two mechanisms simultaneously - reflection, which adds visual depth, and additional light, which makes the room feel brighter and more open. In rooms with limited natural light, the combination of reflection and illumination from an LED mirror can produce a more noticeable sense of spaciousness than a standard unlit mirror.
Are mirrors effective in small Australian apartments?
Yes, and they are particularly practical in this context because they require no structural changes to the property. A large wall mirror, leaned or mounted depending on rental restrictions, can significantly affect the perceived scale of a compact apartment room. Placement opposite windows or in narrow hallways produces the most noticeable results.
Can I use a mirror to make a small bathroom look bigger?
Yes. A large mirror on the wall above the vanity is one of the most effective spatial tools available in a small bathroom. It reflects the bathroom back into the space and amplifies whatever natural or artificial light is present. An LED bathroom mirror compounds this effect by also illuminating the room, making a compact bathroom feel noticeably brighter and more open than the same room with a smaller or unlit mirror.
