A mirror hung over a console table, bathroom vanity, or fireplace mantel must obey both horizontal proportion and vertical eye-level centering.
The 65% to 80% Horizontal Rule
A mirror should measure between 65% and 80% of the width of the furniture piece underneath it. A mirror wider than the furniture creates a top-heavy, precarious feel, while a mirror narrower than 50% looks visually lost.
Centerline Eye Level (60″–65″)
In entryways and living rooms, center the mirror at average adult eye-level (60 to 65 inches from the floor). Above bathroom vanities with a 4-inch backsplash, position the bottom edge 5 to 8 inches above the granite/quartz surface to avoid water splash marks.
