Finding the perfect mirror size is important for bathroom aesthetics and comfort. It shouldn't take up too much space, but it should be big enough - especially in small bathrooms where a larger mirror can reflect more light and create a sense of spaciousness. Let's find out which mirror size is best for a 30-inch vanity.

Width and Height

The ideal width follows the rule that the mirror should be 70-80% of the vanity’s width.

The height of the mirror should be 30-36 inches. This height ensures that all household members can comfortably use the mirror.

Placement

The mirror should be placed above the countertop with a gap of 5-8 inches. This prevents water from splashing onto the mirror and keeps it at a convenient height for everyone to use.

Bathroom Size

Small bathrooms need more light to create the illusion of a bigger space. This can be achieved with the help of mirrors, as they reflect light and create the illusion of a larger bathroom.

If you have a small bathroom, lean more toward bigger sizes (around 28 inches wide). This will ensure that the bathroom has enough reflected light and won't feel cramped.
