Bathroom Vanity Light Size Guide

Updated 2026-04-05Audience: Homeowners, designers, and remodel teamsStage: Consideration

Quick answer

The right vanity light should relate to mirror width, sit at a flattering height, and create even facial illumination without glare or awkward shadow.

How wide should a vanity light be?

Vanity lighting should align with mirror scale and overall bathroom balance rather than simply filling the wall width.

Should you use one fixture or two sconces?

Two sconces often create the most even light beside a mirror, while a single vanity fixture can work well when space or styling calls for a cleaner solution.
