A well-placed mirror is an optical illusion, and quite possibly could be the easiest and most transformative thing you can do for your space. That goes especially if you're living small. With just the right technique (and a few designer tricks) mirrors can visually double your square footage in just about every room of the house.
In the bedroom from Heim Interiors above, the mirror takes the place of an oversized headboard, and visually breaks up the dark brick wall.
If you can afford it, a majorly big mirror will make even a tiny room feel huge, like here in this Toronto space from My Domaine.
If not, multiples can do the work of one big mirror, although I doubt the ornately-framed looking glasses in this Style Me Pretty loft came cheap.
A really do-able look is to take a big-ish floor mirror and lean it against the wall. The best placement is right across from a bright window, like here in this New York City space on Homepolish.
Want to really trick your eyes? Hang a mirror so that the edges hide just behind your window drapes. It gives the illusion of having a another space beyond the window wall, as you can see here on Lonny.
No windows at all? No worries. A window-pane mirror can take the place of one when you accessorize it with curtains, like in this Glitter Guide room.
A mirror placed at the end of a narrow table, like here on Refinery 29, will make the table look extra, extra long.
The same illusion works here, from stylist Sasa Antic, with a wall-mounted mirror reflecting the kitchen counter and cabinets (almost into infinity).
The small kitchen in this Brooklyn townhouse on House Beautiful gets a boost (and extra light) from custom-cut mirrors mounted to the cabinet doors.
A mirror also looks great layered with other furniture, like the bedroom bedside table here from Ollie & Seb's Haus.
The very best place for a floor-length mirror in the bedroom is right across from the doorway. You can see here on My Domaine that it provides a great, big, multi-dimensional view as you enter the room.
And finally, it's good to know that mirrors can also make things disappear, as you can see here with the perfectly-fit mirror mounted to the end of this IKEA bookcase on Design Sponge.
