Golden Ratio (Phi ≈ 1.618)
- Face Length to Width: The ideal ratio is approximately 1.618.
- Length of Nose to Width of Nose: 1:1.618

2. Horizontal Facial Proportions (Symmetry & Width Ratios)
- Facial Width to Length Ratio: The ideal ratio is ~0.78 (Face width ~13.5 cm for males, ~12.5 cm for females, and face length ~17.2 cm for males, ~16 cm for females).
- Zygomatic Width (Cheekbone Width): Ideally, this is the widest part of the face (between 13 to 14.5 cm for males and ~12 to 13 cm for females).

3. Eye Proportions
- Inner Orbital Distance: The ideal distance between eyes is approximately equal to one eye width (~30-35 mm).
- Outer Canthus to Cheekbone: Should align or be slightly above the cheekbone for ideal aesthetics.
- Eye Width: One eye width is about one-fifth of the total facial width (~30-35 mm).
- Eye Spacing: The distance between the eyes should ideally match one eye's width.
4. Eyebrow Proportions
- Eyebrow Arch Position: The highest point of the brow should align with the outer edge of the iris.
- Brow Length: Should extend from the inner eye corner to the outer canthus in a straight line.
- Brow to Eye Distance: Ideal vertical distance is ~10-15 mm.
5. Nose Proportions
- Nose Width: Should align with the inner corners of the eyes (~30-35 mm).
- Nasal Tip Projection: Ideal projection is ~0.6 to 0.67 of the nasal length (~2.4-2.8 cm for males, ~2.3-2.7 cm for females).
- Nose Length: Typically ~5-6 cm for males and ~4.5-5.5 cm for females.
- Alar Width (Nostril Width): Should be roughly equal to the distance between the inner corners of the eyes (~30-35 mm).
6. Lip Proportions
- Lip Width: Should ideally extend to the midpoint of each eye's iris (~4.8-5.2 cm for males, ~4.3-4.8 cm for females).
- Upper Lip to Lower Lip Ratio: The lower lip should be around 1.6 times fuller than the upper lip.
- Philtrum Length: The ideal philtrum length is ~13-15 mm for males and ~11-13 mm for females.
- Chin to Philtrum Ratio: Approximately 2:1 for a balanced appearance.
7. Chin and Jaw Proportions
- Chin Length: The ideal chin length is one-third of the lower face (~3.8-4.5 cm for males, ~3.5-4 cm for females).
- Gonial Angle:
- Males: 120 to 130 degrees for a strong, masculine jawline.
- Females: 125 to 135 degrees for a softer, feminine appearance.
- Jaw Width: Approximately 10-12 cm for males and 9-11 cm for females.
- Chin Projection: Should align vertically with the philtrum or slightly behind it.
8. Cheekbone and Face Width Proportions
- Cheekbone Width: Should be the widest part of the face (~13.5 to 14.5 cm for males, ~12 to 13 cm for females).
- Zygomatic Arch (Cheekbone) Prominence: Should be well-defined but not overly wide.
- Face Width to Cheekbone Ratio: Cheekbone width should be around 70-75% of the total face width.
9. Ear Proportions
- Ear Height: Should match the length from the eyebrow to the base of the nose (~6-7 cm for males, ~5.5-6.5 cm for females).
- Ear Position: Ears should align with the outer corners of the eyes.
10. Hairline Proportions
- Forehead Width: Should match the width between the cheekbones (~12.5-13.5 cm for males, ~11.5-12.5 cm for females).
- Hairline to Eyebrow Distance: Should be equal to the eyebrow to base-of-nose distance (~5.2 cm for males, ~4.8 cm for females).
11. Bilateral Symmetry (Left and Right Balance)
- Eye Position: Both eyes should be at the same horizontal level, with a distance of ~30-35 mm between them.
- Eyebrow Symmetry: Ideal eyebrow length ~5.5-6.5 cm with matching arches and height.
- Cheekbone Symmetry: Cheekbone width should be ~13.5-14.5 cm for males and ~12-13 cm for females, equally prominent on both sides.
- Jawline Symmetry: Gonial angles should be equal, between 120-130 degrees for males and 125-135 degrees for females.
- Mouth Alignment: The corners of the mouth should be at the same horizontal level, ~4.8-5.2 cm apart for males and ~4.3-4.8 cm for females.
- Nostril Symmetry: Both nostrils should have an equal width of ~30-35 mm.
12. Vertical Symmetry (Proportional Alignment)
- Midline Alignment:
- Forehead center to philtrum: ~5.2 cm for males, ~4.8 cm for females
- Philtrum to chin: ~5.2 cm for males, ~4.8 cm for females
- Facial midline deviation should be less than 2 mm.
- Ear Position: Ears should be aligned and measured ~6-7 cm for males and ~5.5-6.5 cm for females.
13. Horizontal Symmetry (Proportional Widths)
- Eye Line: The horizontal line through both eyes should be parallel to the jawline.
- Lip Line: Horizontal lip alignment should measure ~4.8-5.2 cm for males and ~4.3-4.8 cm for females.
- Jaw Angle Line: Gonial angles should be between 120-130 degrees for males and 125-135 degrees for females, aligned with the ear lobes.
14. Soft Tissue Symmetry
- Nasolabial Folds: Should be equally prominent and aligned with the corners of the mouth.
- Smile Symmetry: The distance from the corners of the lips during a smile should match (~5.5-6 cm).
- Chin Symmetry: The chin pad should be evenly distributed and centered with a deviation of no more than 2 mm.
15. Ratios and Measurements for Symmetry
- Midline Deviations: Less than 2 mm from the facial midline is ideal.
- Eye Asymmetry: Eye size or position difference should be less than 1 mm.
- Nasal Deviation: Should not deviate more than 2 degrees from the facial midline.
- Lip Symmetry: The distance from the midline to the corners of the lips should be ~25-30 mm.
- Cheekbone Height: The ideal cheekbone height difference should be less than 2 mm.
16. Lower Face Symmetry (Jaw and Chin)
- Jawline Symmetry: Both gonial angles should match within a 2-3 degree difference.
- Chin Deviation: Ideally, the chin should align with the facial midline without more than 2 mm deviation.
- Chin to Philtrum Ratio: Approximately 2:1 (Philtrum ~13-15 mm for males, ~11-13 mm for females; Chin height ~26-30 mm for males, ~22-26 mm for females).
