What Size Mirror for a 36, 48 or 60 Inch Vanity
Posted by Giles, Inc. on Sep 23rd 2026
What Size Mirror Should You Use for Your Bathroom Vanity?
The right mirror size can completely change the look and feel of your bathroom. A mirror that’s too small can look out of proportion, while one that’s too large can overwhelm the vanity and leave little room for lighting or other fixtures.
So, what size mirror should you choose for a 36-inch, 48-inch, or 60-inch vanity?
A good starting point is to choose a bathroom mirror that is a few inches narrower than your vanity. This creates a balanced look while still providing plenty of reflection space. Your lighting, sink placement, ceiling height, and available wall space should also be considered.
Here’s our simple bathroom vanity mirror size guide.
What Size Mirror for a 36-Inch Vanity?
For a 36-inch bathroom vanity, a mirror approximately 24 to 30 inches wide generally works well.
A 30-inch-wide mirror leaves approximately three inches of vanity width visible on each side, creating a substantial but balanced appearance. A 24-inch mirror leaves more open wall space and can be a great choice if you plan to install sconces on either side of the mirror.
Keep the style of your mirror in mind, too. A reclaimed wood mirror with a substantial frame can have more visual weight than a thin metal or frameless mirror of the same dimensions.
Recommended mirror width for a 36-inch vanity: 24–30 inches
What Size Mirror for a 48-Inch Vanity?
A 48-inch bathroom vanity gives you a little more flexibility. A mirror approximately 30 to 42 inches wide is a good place to start.
A 36-inch-wide mirror is a popular option because it leaves approximately six inches of vanity width visible on either side. This provides plenty of mirror space while maintaining a clean, proportional appearance.
If you're planning to place wall sconces on either side of the mirror, be sure to account for the width of your light fixtures when determining the maximum mirror width.
Recommended mirror width for a 48-inch vanity: 30–42 inches
What Size Mirror for a 60-Inch Vanity?
For a 60-inch bathroom vanity, consider a mirror approximately 42 to 54 inches wide if you're using one large mirror.
A 48-inch-wide mirror is a great starting point. It leaves approximately six inches of vanity width visible on each side while providing a generous reflection area.
If you have a 60-inch double vanity, you have another option: two individual mirrors, with one centered over each sink.
Whether you choose one large mirror or two smaller mirrors depends on the location of your sinks, lighting, and the overall style you want for your bathroom.

Quick Bathroom Vanity Mirror Size Guide
36-inch vanity: 24–30-inch-wide mirror
48-inch vanity: 30–42-inch-wide mirror
60-inch vanity: 42–54-inch-wide mirror
These measurements are starting points rather than strict rules. Always measure your actual wall space, lighting, and fixtures before ordering your mirror.
Should Your Bathroom Mirror Be the Same Width as Your Vanity?
Your bathroom mirror does not have to be the exact same width as your vanity.
In many bathrooms, choosing a mirror that is slightly narrower than the vanity creates a more balanced look and leaves some breathing room on either side.
When choosing your mirror size, consider:
- The width of your vanity
- Sink placement
- The width of the mirror frame
- Wall sconces and other lighting
- Faucets and backsplash height
- Ceiling height
- Available wall space
- Whether you prefer one large mirror or two smaller mirrors
Ultimately, the goal is to choose a mirror that feels proportional to both your vanity and the room.
Don't Forget About Mirror Height
Width gets most of the attention when choosing a bathroom mirror, but mirror height is important too.
Your mirror should be tall enough to provide a comfortable reflection for the people using the bathroom while fitting appropriately between the backsplash and your lighting, ceiling, or other fixtures.
A taller rectangular mirror can also help draw the eye upward, making a bathroom feel taller and more spacious.
Choosing a Mirror for a Double Vanity
If you have a double vanity, both one large mirror and two individual mirrors can work beautifully.
One large mirror can create a clean, cohesive look and make the bathroom feel more spacious. Two separate mirrors can help define each sink area and provide room for decorative lighting between or beside the mirrors.
Before choosing, measure the distance between your sinks and consider where your light fixtures will be installed.
