Frequently Asked Questions
How do I choose the right bathroom mirror size?
The mirror should be 70-80% of the vanity width for balance, typically 2-4 inches shorter than the vanity, and 30-36 inches tall for standard use.
What size mirror for a double vanity?
For double vanities, use one mirror 70-80% of the vanity width or two mirrors, each 35-40% of the width, depending on style.
How high should a bathroom mirror be?
The mirror's top edge should be 70-75 inches from the floor, with the bottom edge 4-6 inches above the sink for optimal usability.

Tips for Choosing a Bathroom Mirror
- Measure your vanity width accurately to ensure proper mirror proportions.
- Consider lighting placement to avoid shadows; mirrors should align with light fixtures.
- For double vanities, choose two mirrors for a symmetrical look or one large mirror for a sleek design.
- Use a taller mirror (36 inches) for taller users or higher vanities.
- Consult a bathroom designer for custom shapes or framed mirrors.
