Understanding Eye Shapes and Ratios
Ocular morphology is determined by comparing vertical aperture height, horizontal palpebral width, canthal tilt inclination, and the distance between the two medial canthi. To measure the exact degree of outer-corner inclination, try our dedicated Canthal Tilt Test.
- Almond Eyes: Oval silhouette with a balanced aspect ratio, where the irises touch both the upper and lower eyelids.
- Round Eyes: Higher vertical aperture aspect ratio (EAR), where white sclera is visible beneath or above the iris.
- Upturned Eyes: Positive canthal tilt where the outer corner rests noticeably above the inner corner.
- Downturned Eyes: Negative canthal tilt where the outer corner slopes below the horizontal line of the inner corner.
- Inter-Canthal Spacing: Standard proportion indicates the distance between the eyes should equal the width of one single eye.
Frequently Asked Questions
FaceMora measures the eye aspect ratio (aperture height divided by width), palpebral fissure inclination angle, and eyelid contour landmarks.
The rule of fifths states that the distance between the two eyes (intercanthal distance) should ideally equal the width of one single eye.
