What Size LED Mirror for a 30-Inch Vanity?
Part of our Mirrors & Lighting guides.
Short answer: for a 30-inch vanity, choose a mirror about 22-28 inches wide. 30 inches is the most common single vanity in US bathrooms. Both the 24x32 and 28x36 fit; the 24-inch-wide mirror leaves room for a towel hook or sconce on one side.

Our pick for a 30-inch vanity
The recommended VEVOR size fits this width with balanced margins on each side and includes front + backlit LEDs, anti-fog and three color temperatures.
If you keep a plain mirror
Add a vanity light about three-quarters of the mirror width. For this vanity, a matching VEVOR fixture is the right length.
Before you buy
- Measure the wall between obstacles, not just the vanity.
- Find the electrical box: hardwired mirrors need it behind the mirror area.
- Check that cabinet doors or a medicine cabinet won't collide with the mirror.
Vertical or horizontal?
A 30-inch vanity is wide enough for either orientation. A vertical 24x32 mirror suits standard 8-foot ceilings and makes the room feel taller. A 28x36 hung vertically gives more mirror area and a more generous look while still leaving a margin.
Example layout
Vanity 30 in, faucet top at about 42 in. A 28x36 mirror hung vertically with its bottom at 48 in reaches 84 in at the top. On an 8-foot (96 in) ceiling that leaves a pleasant 12 inches above. Centered over the vanity, it leaves only about 1 inch of margin on each side, so choose the 24-inch-wide mirror if you want visible margins.
Storage combos
Many 30-inch vanities have limited storage. Pair the LED mirror with an over-toilet cabinet or a recessed medicine cabinet on a side wall.
Lighting fixture alternative
If you keep a framed mirror, a 3-light fixture of about 20 inches fits above it. A front-lit LED mirror, however, gives more even face lighting than any overhead fixture.
