7 Ways to Use Mirrors to Make Any Room Look Bigger

The Cheapest Room Upgrade You're Probably Not Doing

I've moved apartments more times than I care to admit, and every single time I've stood in a new space thinking the same thing: this room feels so small. Not because it actually was small, but because I hadn't figured out the one trick that changes everything. No, it's not a fresh coat of white paint. It's not decluttering (though, yes, also do that). It's mirrors — and not just slapping one above the console table and calling it a day. I mean actually using them with intention.

Once I started treating mirrors as a design tool rather than just a functional necessity, my spaces transformed. We're talking genuinely roomier-feeling apartments without moving a single piece of furniture or spending a fortune. If you've been sleeping on this, here are the 7 ways to use mirrors to make any room look bigger that I now swear by.

Where You Put It Matters More Than What It Looks Like

Here's the thing nobody tells you when you're scrolling through home inspo on Pinterest: a beautiful mirror in the wrong spot does absolutely nothing for your space. The placement is everything. Before you even think about frames and finishes, think about light.

• Opposite a window: This is the golden rule. A mirror facing a window doesn't just reflect the view — it essentially doubles your natural light and makes the room feel like it has twice the square footage. In a small bedroom, lean a full-length mirror against the wall directly across from your window and watch the whole room open up.
• Along the longest wall of a hallway: Narrow entryways feel like a bottleneck until you add a tall, slim mirror running the length of the wall. Suddenly it reads as a proper foyer. A frameless or thin-framed style works especially well here because it feels seamless rather than decorative.
• Perpendicular to your living room window: If your sofa wall is opposite a window, hang a large mirror on the adjacent wall instead. It catches the light at an angle and spreads it across the whole room — a game-changer for north-facing spaces that always feel a little dim.
• Above the vanity, but go wider than you think: In a bathroom, an oversized mirror that stretches edge to edge above the sink cabinet makes the room feel significantly more spacious. Pair it with side lighting rather than overhead, and it's both flattering and functional.

The Size Rule That Changes Everything

If I had to pinpoint the single most common mirror mistake I see in people's homes, it's going too small. A dainty mirror on a large wall looks sweet, but it does almost nothing for the sense of space. For a mirror to actually make a room feel bigger, it needs to occupy at least a third of the wall it's on. That might feel bold at first, but trust the process — scale is what creates impact.

A large, simple mirror leaned casually against the wall (rather than hung) also adds that effortless, editorial quality that makes a room feel styled rather than decorated. It's one of those moves that looks expensive and considered but is genuinely one of the most accessible upgrades you can make to any room, rented or owned, big or small.

The 7 ways to use mirrors to make any room look bigger aren't complicated — they just require a little intention. Get the placement right, go bigger than feels comfortable, and let the light do the rest.
