From the front, which point should line up horizontally to assess symmetry of the upper body?

• A. Eyes Level
• B. Center of Skull
• C. PSIS Level
• D. Knees Level

Answer: (A)

When you assess symmetry from the front, use a horizontal reference that runs through the eyes. The eyes provide a clear, stable marker on the face to judge levelness; if both eyes sit on the same horizontal plane, the head is upright and the upper body tends to align evenly across the shoulders. The center of the skull isn’t a practical, easily observable reference for a quick front view; the PSIS level relates to the pelvis and is more relevant for lower-back/pelvis symmetry, while knees level targets the lower body. So, aligning to the eyes gives the best, immediate sense of whether the upper body is horizontally level.
