LED Bathroom Mirror Size Guide
Part of our Mirrors & Lighting guides.
The most common mistake with bathroom mirrors is going too wide. A mirror that is a few inches narrower than the vanity looks balanced and leaves room for sconces or a towel hook.
Mirror size by vanity width
| Vanity width | Suggested mirror |
|---|---|
| 24 in | 20-24 in wide (e.g. 24×32 vertical) |
| 30 in | 24-28 in wide |
| 36 in | 30-32 in wide (32×48 vertical or horizontal) |
| 48 in | 36-44 in wide |
| 60 in double | One 54-60 in mirror (36×60 horizontal) or two 24 in |
| 72 in double | One 66-72 in mirror (36×72 horizontal) or two 30 in |
Mounting height
Hang the bottom of the mirror about 5-10 inches above the faucet or backsplash, and aim for the center to sit near average eye level, around 60-65 inches from the floor.
Lighting specs that matter
- Front-lit light falls on your face (shaving, makeup).
- Backlit light glows on the wall (ambience, night light).
- Color temperature: 3000 K warm, 4000 K neutral, 5000-6000 K daylight.
- Anti-fog: a heated pad behind the glass; nice in small bathrooms without strong ventilation.
Wiring
Many LED mirrors can hardwire to the old vanity-light box. Bathroom electrical work must follow local code; hire a licensed electrician if unsure.
Round and specialty shapes
Round mirrors look best a little narrower than for rectangular mirrors, often about two-thirds of the vanity width. A 24-30 inch round mirror suits a 36-inch vanity. Pill-shaped and arched mirrors follow the rectangular rules for width.
Vertical vs horizontal
- Vertical: single sinks, narrow walls, standard ceilings; makes the room feel taller.
- Horizontal: double vanities, wide single vanities, low ceilings.
Clearances to check
- Light switches and outlets beside the mirror.
- Medicine cabinet doors or wall cabinets that open into the mirror's space.
- Ceiling height: leave a few inches above the mirror.
- Side walls: a few inches of wall on each side looks better than touching.

Frequently asked questions
Should the mirror be wider than the vanity?
No; slightly narrower usually looks best.
Can I put one big mirror over a double vanity?
Yes. A 36×60 or 36×72 horizontal LED mirror is a popular choice for double vanities.
