Picking the right mirror for your bathroom vanity isn’t just about style—it’s about getting the size just right.

In this guide, we’ll walk you through how to choose the ideal mirror width, explore common mirror and vanity pairings, and help you find the best fit for your bathroom setup.

How wide should a mirror be over a bathroom vanity?

A mirror should be about the same width as your bathroom vanity, or slightly smaller, to create a balanced look. This ensures the mirror is both functional and visually appealing

Key Takeaways

  • The width of the mirror should generally be the same as, or slightly smaller than, the width of your vanity.
  • Mirrors that are too small or too large can disrupt the balance of your bathroom’s design.
  • Consider the overall dimensions of the bathroom, as well as the number of users, when choosing the mirror size.

Understanding the Basics: Mirror Size Relative to Vanity

When deciding on the appropriate mirror width for a bathroom vanity, the first thing to consider is the size of your vanity itself. 

When designing or upgrading a bathroom, selecting the right mirror for over your vanity can significantly impact both the functionality and aesthetics of the space. 

While choosing the right style and frame is important, one of the most essential considerations is the width of the mirror. 

The width of the mirror should complement the vanity size, creating a balanced and harmonious look. 

In this article, we’ll dive into how to determine the ideal width for your bathroom mirror, explore different vanity and mirror configurations, and help you choose the best size for your space.

Ideally, the mirror should be wide enough to provide a functional reflection, but not so large that it overwhelms the space or looks out of place.

Standard Bathroom Vanity Sizes

Before we delve into the specifics of mirror sizing, let’s quickly look at the common sizes for bathroom vanities:

Single Vanities: These are usually between 24 inches to 36 inches wide. For these sizes, the mirror typically ranges from 20 inches to 32 inches in width.

Double Vanities: These can range from 48 inches to 72 inches wide, with mirrors that span 40 inches to 60 inches in width, depending on the vanity's width and style.

Now, let’s explore the general guidelines for selecting a mirror width in relation to the vanity.

Mirror Width for Single Vanities

When it comes to single vanities, the width of the mirror is crucial for ensuring it provides adequate reflection and suits the vanity's scale.

Ideal Mirror Width for Single Vanities

Mirror width equal to the vanity width

For a balanced look, a mirror that matches the vanity’s width is an excellent choice. For example, if you have a 36-inch vanity, a 36-inch mirror creates a seamless, proportional look.

Mirror width slightly smaller than the vanity width

In some cases, you might opt for a mirror that is slightly smaller than the vanity, usually by 2-6 inches. 

This design choice is ideal if you want to add a bit of space around the mirror for decorative purposes or if you want to avoid overwhelming the wall.

Example: If your vanity is 30 inches wide, consider a mirror between 26 inches and 30 inches wide. This size will give you a functional reflection without overcrowding the space.

Mirror Width for Double Vanities

Double vanities tend to be more expensive, and selecting the right mirror width becomes even more important to maintain a cohesive look. 

A mirror that is too small can make the space feel fragmented, while a mirror that is too large may overpower the room.

Ideal Mirror Width for Double Vanities

Mirror width equal to the total vanity width

For a clean, balanced appearance, you might want a mirror that spans the full width of the vanity. 

For instance, if you have a 60-inch double vanity, a mirror that is 60 inches wide will offer a large, functional reflection and a uniform look.

Mirror width slightly smaller than the total vanity width

If you prefer some space around the mirror for decorative features, a slight reduction in mirror size (2-4 inches smaller) can create a bit of contrast and allow for more wall space to be visible.

Example: For a 72-inch double vanity, you can choose a mirror in the range of 60-72 inches, depending on the look you want to achieve. 

A mirror that is 60 inches wide will provide some visual breathing room, while a mirror that is 72 inches wide will provide a more grand and seamless design.

Special Considerations for Mirror Placement

Besides width, the placement of the mirror above your vanity also plays a role in how well it fits the space. 

Here are some additional considerations when deciding how wide the mirror should be and how it should be positioned:

Mirror Height and Placement

Standard Height

The mirror should generally be positioned so that the top of the mirror is around 78 to 80 inches from the floor. 

This allows most people to see themselves in the mirror comfortably, especially when standing.

Eye Level

For best functionality, the centre of the mirror should be aligned with the eye level of the primary user, typically around 57 to 65 inches off the ground.

Spacing Between Mirror and Vanity

Leave a 3 to 4-inch gap between the top of your vanity and the bottom of the mirror. This ensures that the mirror does not look like it's floating and creates a balanced, clean look.

Style of the Bathroom

The style of your bathroom also influences the mirror size. 

For example, a more minimalist or contemporary bathroom might look better with a sleek, frameless mirror that’s the same width as the vanity. 

On the other hand, a more traditional or rustic bathroom might benefit from a mirror with a decorative frame that is slightly smaller than the vanity to maintain a more dynamic look.

Can the Mirror Be Larger Than the Vanity?

While it’s more typical for the mirror to be the same width as the vanity or slightly smaller, there are cases where a larger mirror can work well. 

If you have a particularly spacious bathroom or want to create a bold statement, choosing a mirror that’s larger than the vanity can provide an interesting visual contrast.

Considerations for a Larger Mirror

Proportions

Ensure the mirror’s size is proportional to the room. A mirror that is too large can make the space feel unbalanced or out of proportion with the rest of the elements in the bathroom.

Design Statement

A large mirror can act as a striking design feature. For example, a round mirror over a rectangular vanity or a large mirrored wall can create a unique focal point in the room.

How to Measure for the Right Mirror

To ensure you select the right size mirror, follow these simple steps:

Measure the width of the vanity: Use a tape measure to find the exact width of your vanity.

Determine the mirror size: Decide whether you want a mirror that matches the vanity width or is slightly smaller. Make sure the mirror is centred above the vanity.

Account for spacing: Leave around 3 to 4 inches of space between the mirror and the vanity to avoid a cramped appearance.
