Ideal Facial Ratios + Measuring Guide by Human
Introduction
Facial ratios are one of the most objective methods available for analysing one's facial aesthetics, with the ideal measurements appearing frequently in the top % of faces. These ratios can be used to point out strengths and weaknesses, helping to improve facial harmony. While no single ratio determines attractiveness, the combination of many working together is what makes up a person's facial harmony.
If you are interested in measuring your own ratios (not sure why you would want to though JFL
) you must first take a photo with the according instructions:• Look directly into the camera
• Keep your head level with no tilt or rotation
• Ensure the camera is perpendicular to your face
• Stand 6 feet from the camera and zoom, minimising lens distortion
• Use appropriate lighting, ensuring all facial features are visible
Any photo used must fit this Criteria in order for an accurate rating to be concluded.

2. Measuring Guide
Note: Facial harmony is determined by the interaction of multiple ratios and features rather than any single measurement.
Bizygomatic width ÷ upper-face height (brow to upper lip)
FWHR affects the overall balance between facial width and height, with a low FWHR causing the face to appear long and thin, and a high FWHR causing the face to appear short and compressed. Significant deviations can very much reduce overall facial harmony.
Bizygomatic width ÷ total facial height (hairline to chin)
tFWHR affects the relationship between facial width and total facial height, with a low value producing a long-face appearance and a high value creating a shorter, more compact face.
Midface height ÷ facial width
MFR affects the balance of the midface relative to the rest of the face, with a high MFR producing a compact midface and a low MFR producing a long midface. The closer to 1:1 the better and any large deviations can draw attention away from the eye area.
Bigonial width ÷ bizygomatic width
Jaw Width affects the strength and shape of the lower face, with a narrow jaw producing a thin appearance and an excessively wide jaw creating a disproportionate lower face that looks retarded (JFL)
Distance between gonions ÷ bizygomatic width
Bigonial Width affects the visual strength of the jaw and lower face, with a low ratio creating excessive tapering and a high ratio producing a broad, square appearance.
Neck width ÷ bigonial width
Neck Width affects the transition between the head and body, with a narrow neck making the head appear larger and a very wide neck reducing facial definition. Significant deviations can negatively impact overall aesthetics.
Angle between the inner and outer canthus
Canthal Tilt affects eye shape and expression, with a negative tilt often producing a tired or aged appearance and a positive tilt creating a more alert and youthful look. Significant deviations can greatly impact eye-area aesthetics as is one of the more noticeable ratios.
Interpupillary distance ÷ facial width
ESR affects the balance between the eyes and overall facial width, with low values creating close-set eyes and high values creating wide-set eyes. Again a very noticeable ratio, with even medium deviation greatly affecting the eye area.
Intercanthal distance ÷ eye width
ES affects eye spacing, with low values producing close-set eyes and high values producing wide-set eyes with significant deviations making the eye area appear disproportionate.
Distance between inner canthal ÷ facial width
Inner Canthal Distance affects the spacing between the eyes, with a low distance creating crowding and a high distance creating excessive separation.
Distance between outer canthal ÷ facial width
Outer Canthal Distance affects the overall width of the eye area, with low values creating a narrow appearance and high values creating excessive width.
Angle formed by the inner corner of the eye
Medial Canthal Angle affects the appearance of the inner eye area, with extreme values reducing eye aesthetics and harmony. Significant deviations can negatively affect the overall attractiveness of the eye region.
Palpebral fissure length ÷ palpebral fissure height
PFL affects eye shape, with low values producing rounder eyes and high values producing narrower eyes. Is a factor in whether a face has 'hunter' v.s 'prey' eyes.
Subnasale to menton distance ÷ total facial height
Lower Third affects the balance of the lower face, with a long lower third creating an elongated appearance and a short lower third creating a compressed appearance.
Lower Third affects the balance of the lower face, with a long lower third creating an elongated appearance and a short lower third creating a compressed appearance.
Eye level to cheekbone prominence ÷ facial height
Cheekbone Height affects facial structure and definition, with low cheekbones producing a flatter appearance and high cheekbones contributing to stronger facial architecture, and is frequent in the top % of faces.
Chin height ÷ philtrum length
Chin to Philtrum affects the balance between the lower face and upper lip region, with a long philtrum or short chin often associated with ageing and reduced harmony. Significant deviations can be a huge flaw in the face and is very noticeable.
Upper lip height ÷ lower lip height
Lip Proportions affect the balance of the mouth area, with disproportionate upper and lower lips disrupting facial harmony and can make the mouth region appear unbalanced.
Mouth width ÷ nose width
Nose to Mouth Width affects the relationship between the nose and mouth, with an excessively wide or narrow mouth relative to the nose reducing facial balance. Significant deviations can draw unwanted attention to the centre of the face.
Nose width ÷ bizygomatic width
Nose to Zygo affects how proportional the nose appears relative to facial width, with a nose that is too wide or too narrow disrupting harmony in the midface.
Nose width ÷ inner canthal distance
Nose Width to ICD affects the relationship between the nose and eye spacing, with a nose that is too wide or narrow relative to the eyes reducing central facial harmony.
Nose width ÷ nose height
Nose Width to Height affects nasal shape, with high values creating a wider nose and low values creating a narrower nose. - both, at extremes, are negative.
Angle formed between the alar base and facial midline
Ipsilateral Alar Angle affects nasal shape and orientation, with extreme angles reducing symmetry and harmony within the nose.
Distance between mouth corners ÷ distance between pupils
Eye-Mouth-Eye affects the relationship between mouth width and eye spacing, with disproportionate values making either the eye area or mouth appear dominant.
Nose height ÷ chin height
Nose to Chin affects the balance between nasal and chin projection, with an overly dominant nose or weak chin at either end of the spectrum. Significant deviations can negatively impact both frontal and profile aesthetics.
Compare nostril width to the position of the medial canthus
Nostril Width affects nasal harmony, with overly wide nostrils making the nose appear broader and overly narrow nostrils reducing proportionality.
Compare mouth corners to the vertical line through the inner eye corners
Commissure Alignment affects the positioning of the mouth relative to the eyes, with poor alignment reducing symmetry and lower-face harmony.
Compare the lengths of the upper face (hairline to eyebrows), midface (eyebrows to nose), and lower face (nose to chin)
Facial Thirds affect the balance between the upper, middle, and lower regions of the face, with one third becoming disproportionately long or short disrupting overall harmony. These three areas should be able to be smoothly separated into equal thirds, and if one third is proportionally bigger/smaller, facial harmony can be greatly affected.
Distance from eye to eyebrow
Brow Height affects eye framing and upper-face aesthetics, with brows that sit too high or too low altering expression, and bringing attention away from the eye shape/pupils.
Temple width ÷ bizygomatic width
Bitemporal Width affects the balance between the upper face and cheekbones, with narrow temples creating a pinched appearance and broad temples creating stronger upper-face support.
Frontal angle formed by the ramus and jawline
Jaw Frontal Angle affects jaw shape and lower-face structure, with acute angles creating excessive tapering and wide angles reducing definition.
Difference between the ipsilateral alar angle and jaw frontal angle
IAA–JFA Deviation affects the harmony between nasal and jaw structures, with larger deviations creating disharmony between the upper and lower face.
Angle between the medial and lateral ends of the eyebrow
Eyebrow Tilt affects expression, eye aesthetics, and facial dimorphism, with insufficient tilt creating a flatter appearance and excessive tilt appearing unnatural. Significant deviations can negatively impact the attractiveness of the eye area.
