A photorealistic diagram of a human face with various anatomical measurements labeled with lines and numbers.

Reference Unit: Bizygomatic width (facial bone width) ≈ 150 mm (base reference for proportions). Head height (from hairline to chin) ≈ 220 mm. General Layout and Ratios (relative to 150 mm / 220 mm): Eye width (each) ≈ 33.0 mm (≈ 22% of face width). Distance between eyes (inner corner to inner corner) ≈ 33.0 mm (equal to one eye width). Eye line center (horizontal line through the middle of the eyes) ≈ 99.0 mm from the hairline (≈ 45% of head height). Outer eye corner tilt: −3° (slightly downward). Nose Details: Nose length (from nasion/lower brow to tip) ≈ 57.2 mm (≈ 26% of head height). Nose width at widest point (base of the bridge/nostrils) ≈ 18.0 mm (≈ 12% of face width). Bridge angle relative to vertical ≈ 6° (slightly forward). Lips and Mouth: Mouth width (lip corners, relaxed) ≈ 69.0 mm (≈ 46% of face width). Total mouth height ≈ 18.0 mm; upper lip ≈ 7.2 mm, lower lip ≈ 10.8 mm. Chin projection (from below lower lip to tip of chin) ≈ 14.0 mm (mildly pronounced). Jaw, Chin, and Cheeks: Jaw angle (mandibular region) ≈ 115° (relatively sharp/narrow, not square). Cheekbone projection (zygomatic width) ≈ 132.0 mm (≈ 88% of face width) — cheeks are relatively narrow and close to face width. Jaw contour: smooth and sloped toward chin, not strongly squared. Forehead, Hair, and Eyebrows: Forehead height (from hairline to eyebrows) ≈ 39.6 mm (≈ 18% of head height). Hairline shape: slightly V-shaped (widow’s peak) with central dip ≈ 4.5 mm.
