What Size Bathroom Mirror Do I Need?

A bathroom mirror should feel proportional to the vanity while leaving enough breathing room for trim, faucets and lighting. Vanity width is a useful starting point, but sink layout and the amount of clear wall space above the counter also matter.

Bathroom Mirror Width

For a single mirror, a width slightly narrower than the vanity often creates a balanced look. With a double vanity, you can choose one larger mirror or two separate mirrors centered over the sinks.

Round and Arched Vanity Mirrors

Round and arched mirrors can soften the straight lines of a vanity. When using two mirrors, consider the combined visual width plus the space between them rather than sizing each mirror in isolation.

Mirror Height and Lighting Clearance

Leave enough space above the faucet or backsplash and confirm that the mirror will not crowd sconces, an overhead vanity light, ceiling trim or nearby cabinetry. The calculator uses your measurements to help balance those clearances.

Bathroom Mirror FAQ

How wide should a bathroom mirror be compared with the vanity?

A bathroom mirror is usually a little narrower than the vanity. The best width also depends on whether you use one mirror or separate mirrors over two sinks.

Should I use one large mirror or two mirrors over a double vanity?

Either can work. One large mirror creates a continuous look, while two mirrors can center each sink individually. The calculator compares the mirror arrangement with your vanity width.

How high should a bathroom mirror hang above the vanity?

The bottom of the mirror should clear the faucet and backsplash while remaining comfortable for everyday use. Your available wall height and lighting also affect placement.

Can I use round or arched mirrors over a bathroom vanity?

Yes. Round and arched mirrors can work with single and double vanities as long as their total width, spacing and lighting clearance fit the vanity area.
