How Wide Should a Mirror Be Over a Bathroom Vanity?

Choosing the right width for a mirror over a bathroom vanity is essential for both functionality and aesthetics. Here are some guidelines to help you determine the ideal width for your mirror:

General Guidelines:

Proportionate to the Vanity:

Single-Sink Vanity: The mirror should be slightly narrower than the vanity. A good rule of thumb is to choose a mirror that is about 70-80% of the width of the vanity. This provides a balanced look without overwhelming the space.

Example: For a 900 mm wide vanity, a mirror width of approximately 600-700 mm would be ideal.

Double-Sink Vanity:

Single Large Mirror: If using one large mirror over a double-sink vanity, the mirror should be slightly narrower than the vanity, leaving a small gap on either side.

Example: For a 1500 mm wide vanity, a mirror width of approximately 1300-1400 mm would be appropriate.

Two Separate Mirrors: Alternatively, you can use two mirrors, each centered over the sinks. Each mirror should be slightly narrower than half the width of the vanity.

Example: For a 1500 mm wide vanity, each mirror should be approximately 600-700 mm wide.

Height Considerations:

Typical Mirror Height: Mirrors are typically 700-900 mm high, but this can vary based on the height of the users and the design of the bathroom.

Top Alignment: Ensure the top of the mirror is at least a few inches (100-150 mm) above the eye level of the tallest person using it.

Style and Aesthetic Considerations:

Frame vs. Frameless:

Framed Mirrors: These can add a decorative element and should be measured from the outer edge of the frame. Ensure the frame doesn’t make the mirror too wide for the vanity.

Frameless Mirrors: These provide a sleek, modern look and can be slightly larger as they don’t have the added bulk of a frame.

Lighting:

Side Lighting: If you plan to have sconces or side lighting, ensure there is enough space on either side of the mirror for the fixtures.

Integrated Lighting: Mirrors with integrated lighting can provide a clean look and ensure even illumination.

Symmetry:

Balanced Look: The mirror should be centered over the vanity or sink to provide a balanced and symmetrical appearance. If you have a double vanity, centering the mirrors over each sink creates a harmonious look.

Conclusion:

For a single-sink vanity, the mirror should be about 70-80% of the vanity width, typically 600-700 mm wide for a 900 mm vanity. For a double-sink vanity, you can choose one large mirror slightly narrower than the vanity (1300-1400 mm for a 1500 mm vanity) or two separate mirrors each 600-700 mm wide. Consider the height, frame style, and lighting when choosing the mirror to ensure it complements your bathroom’s design and provides functional illumination.
