What size mirror for your space: a practical guide
Most mirror regret is size regret. Too small and it floats on the wall like an afterthought. Too big and it crowds everything around it. The good news: getting it right is mostly arithmetic, and you only need a tape measure and two minutes.
Full length: start at 1700mm
For a head-to-toe reflection, a leaning mirror needs to be at least 1700mm tall. Our Sienna 1700 x 610 is the slim one: it fits a narrow hallway wall, the strip beside a wardrobe, or a bedroom corner that can't take anything wider. The Sienna 1800 x 850 is the size most people end up choosing, tall enough to add height to the room and wide enough to pull light across it. Both are in stock now.
The Sienna 2000 x 1100 is the statement piece. For scale, a standard door is 2040mm, so this mirror is nearly door-sized. It needs a wall that can carry it. It's on pre-order, arriving August 2026.
One rule that isn't optional: any leaning mirror gets anchored to the wall with the supplied fixings so it can't tip. Every mirror we sell comes with what you need, and the installation guide walks you through it.
Above furniture: the two-thirds rule
For a mirror above a console, sideboard or buffet, aim for a mirror about two-thirds the width of the furniture under it. A 1.5 metre sideboard wants roughly a metre of mirror. Hang it so the bottom edge sits 150 to 250mm above the surface, close enough to feel connected, with room for a lamp or a vase in front.
Our wall shapes cover the usual furniture widths: the Vittoria at 1100 x 900 suits most consoles, and the Danielle runs 1500mm across for long, low sideboards. The wall range is on pre-order for August 2026, so measure now and you're ready when they land.
Vanities and bathrooms
Above a basin, centre the mirror at average eye height, roughly 1600 to 1650mm from the floor, and keep the mirror a little narrower than the vanity. The Elena at 900 x 600 and the Jasmine at 800mm across are drawn for exactly this job. One honest note: our mirrors are made for dry indoor spaces, so give them a powder room or bedroom vanity rather than a steam-heavy shower zone.
Check it before you buy
Every product page lists full dimensions in millimetres and includes a drawn-to-scale diagram, so you can see the real proportions rather than guess from a styled photo. The sculpted shapes have proper dimension drawings, like these:

The simplest trick of all: cut a sheet of newspaper or baking paper to the mirror's size and tape it to the wall. Live with it for a day. You'll know.
