Choosing the right vanity light for your bathroom is key to both style and functionality. The light should complement your mirror's size for balanced aesthetics and optimal lighting.
In this guide, we’ll show you how to find the ideal width for your vanity light, ensuring it provides the perfect glow and enhances your bathroom's design.
How wide should a bathroom vanity light be compared to the mirror?
The vanity light should generally be about the same width as the mirror, or a little wider. This ensures even lighting, giving a balanced look and reducing shadows around the face. When deciding how wide should a mirror be over a bathroom vanity, it's helpful to keep lighting in mind—matching the width of the mirror and light fixture can create both functional and aesthetic harmony.
Key Takeaways

The width of the vanity light should generally be around 70-80% of the width of your mirror.

Consider the type of mirror and the lighting needs in your bathroom when selecting the right size of light.
Why Does the Size of Your Vanity Bathroom Light Matter?

The size of your vanity light is essential for two main reasons: it affects the lighting in your bathroom and contributes to the overall aesthetics of the space.
A properly sized light will provide sufficient illumination for grooming tasks while also creating a harmonious and balanced look.
An ill-proportioned light can throw off the balance of the space and may not provide enough illumination for tasks like shaving or applying makeup, which is why choosing a bathroom mirror with LED light can make a noticeable difference.
Standard Sizing for Vanity Lights
When choosing the width of your vanity light, the general guideline is that the light should span 70-80% of the width of your mirror.
For example, if your mirror is 36 inches wide, a light fixture that is 25-30 inches wide would be appropriate.
This sizing ensures that the light source is balanced and does not overwhelm the mirror, while also providing adequate illumination across the vanity area.
1. Small Mirrors (Under 24 inches wide)
For smaller mirrors, such as those used in powder rooms or guest bathrooms, a narrow light fixture (about 16-20 inches wide) will provide enough coverage.
A smaller fixture will not overpower the mirror, and it will create a neat, streamlined look.
2. Medium Mirrors (24 to 36 inches wide)
For mirrors of this size, the vanity light should be around 20-30 inches wide. This will ensure that the light is evenly distributed and that the mirror isn’t overwhelmed by a larger light fixture.
The light should provide adequate illumination for grooming tasks without being too stark or dim.
3. Large Mirrors (Over 36 inches wide)
For large mirrors, such as those in master bathrooms, the light fixture should be 30-40 inches wide or even more.
Larger mirrors require a more substantial light source to ensure that the entire mirror is adequately lit.
In some cases, you may need to use multiple light fixtures to ensure sufficient lighting.
Considerations for Vanity Light Placement

While the width of the light fixture is important, how the light is positioned can also impact its effectiveness.
In addition to ensuring the proper width, the placement of the vanity light relative to the mirror is crucial for both function and appearance.
1. Height of the Vanity Light
The height of the vanity light should be placed about 75 to 80 inches from the floor. This ensures that the light is positioned at the correct level to provide adequate lighting for your face. When planning your bathroom setup, a common question arises—should bathroom mirror be same width as vanity? While it's not a strict rule, keeping the mirror the same width or slightly narrower than the vanity often creates a balanced and visually appealing look.
If you’re installing multiple light fixtures above the mirror, make sure they are evenly spaced to create balanced light.
2. Above or Beside the Mirror?
The placement of the vanity light can also affect its effectiveness.
Traditionally, the light is mounted above the mirror, but pairing side-mounted lighting with a gold round mirror with light can create a more modern and stylish aesthetic.
Side-mounted fixtures provide even lighting on both sides of the face, which can reduce shadows, making them a good option for tasks like makeup application or shaving.
Above the mirror: Provides general illumination and is a more traditional approach.
Beside the mirror: Offers more even light distribution, especially when placed at eye level on either side of the mirror.
3. Consider the Mirror Shape
The shape of your mirror can also impact your choice of vanity light. For round or oval mirrors, it may be more aesthetically pleasing to use a single fixture above the mirror.
For rectangular mirrors, multiple light fixtures on either side or a longer fixture above the mirror may be more fitting to achieve a balanced look.
Frequently Asked Questions
1. What is the best size vanity light for a 24-inch mirror?

2. Can I use multiple light fixtures above my bathroom mirror?

Choose bulbs with a color temperature of 3,000 to 5,000 Kelvins for a bright, daylight-like effect. For brightness, aim for 2,000 to 3,000 lumens, depending on your lighting needs.
