The standard rule of thumb for vanity mirrors is to choose a mirror that is 2–4 inches narrower than the vanity cabinet on each side, and positioned so the center of the mirror sits at roughly eye level — around 60–65 inches from the floor for most adults.
For a single-sink vanity (31–36 inches wide), a 24×36-inch mirror is the most common fit. For a double vanity (60–72 inches wide), a 48–60-inch wide mirror — or two individual mirrors mounted side by side — maintains the proportional rule. Xramfy's 5-layer float glass ensures that whatever size you choose, the reflection stays 1:1 with no barrel distortion across the full width of the mirror.
