  4. Clearance from Countertop: Leave 4–6 inches above the backsplash for practicality.

  5. Ceiling Considerations: Ensure a 6–12 inch gap between the mirror top and ceiling, depending on ceiling height.

Using a Mirror to vanity ratio calculator can simplify this process and prevent common sizing mistakes.
