How to Choose the Right Vanity Mirror
Mirror size is one of the most overlooked but essential elements of interior design. The right mirror balances proportion, adds visual clarity, and helps ground your vanity setup. An ill-fitting mirror can throw off the scale of a space, making it feel cramped or unfinished. In bathrooms where every inch matters, sizing is not just a style decision—it’s a functional one too.
What is a bathroom vanity and a vanity mirror?
A bathroom vanity is typically the cabinet or structure that supports the sink, offers storage, and anchors the overall style of the room. The mirror above it, often called a vanity mirror, complements that setup by providing both practical use and visual balance. It’s where you check your face in the morning, but it’s also a major style feature that can enhance or distract from the vanity below.
The importance of choosing a mirror size
When choosing a mirror size, the general rule is that it should be two to four inches narrower than the vanity on each side. This creates a balanced visual frame without overwhelming the cabinet. For double vanities or larger setups, you can use either one large mirror or two individual mirrors centered over each basin. Height depends on ceiling height and lighting placement, but around 30 to 40 inches tall is common for most spaces.
