Mirror Width = Vanity Width - 4 inches (or 90% of vanity width)
Example: For a 48 inch wide vanity, ideal mirror width is 36-46 inches (0.75-0.95 ratio). A 42 inch mirror centered above the vanity works perfectly

How wide should a bathroom mirror be?

The mirror should be 1-2 inches narrower than the vanity on each side, or about 90-100% of vanity width. Never wider than the vanity.

How high should I hang a bathroom mirror?

Center the mirror at eye level, typically 5-6 feet from floor. Leave 4-6 inches between mirror bottom and backsplash/faucet.
