These findings are more consistent with recent trends in cosmetic medicine, with many clients aiming for a fuller upper lip. Meanwhile, in a 2017 study published by the Journal of Cranio-Maxillofacial Surgery, researchers found that an upper to lower lip ratio closer to 1:1 was considered the most attractive 3. The study found that lips that were big, but not overly big, were ranked most attractive by both male and female respondents. Believe it or not, bigger isn’t always better-and these findings reflect the proportions typically found in human anatomy. In general, women with fuller lips and greater vermillion height (the space between your lip tissue and normal skin) relative to their facial width are considered more attractive.Īccording to a 2017 study by JAMA Facial Plastic Surgery, an upper to lower lip ratio of 1:2 is considered the most attractive 2. In part, the appearance of the lips plays an important role in the overall attractiveness of a person’s face. While studies have revealed the perfect lip proportions according to science, the most attractive lip ratio is not always in line with these findings. This translates to the top lip being smaller than the bottom lip in height or slightly less than a 40:60 ratio. The lip depicted in this picture has a different ratio of 0.45:0.55. From the Front View of the face:Īccording to lead researcher Professor Nuray Bayar Muluk, the ideal lip projections reflects the “golden ratio” or “divine proportion”-1:1.618. From a Horizontal View of the Face:īased on the golden formula, the top lip should extend no more than 3.5 mm, and the bottom lip should not extend more than 2.2 mm (from an imaginary line from the subnasion (SN) to the pogonion -see diagram above). To put this in simpler terms, 2.2 x phi = 3.5. The ideal width of your eyes (at the lateral canthus) is phi x the width of your mouth. Another example is that the ideal distance between your pupils to your chin is phi x the distance of your pupils to your hairline. For example, the ideal ratio of the width of your nose to month is the width of your nose times phi. The golden ratio’s importance is that it’s believed to hold the secret to beauty in aesthetically attractive proportions of the face. As an irrational number, like pi 3.14…, it goes on and on in no discernable pattern. The golden ratio, denoted by the symbol phi, is a number that approximates to 1.618-at least those are the numbers that I remember. Moreover, according to Muluk, “sausage” or “duck” lips do not merely occur from over-correction during lip injections or surgical procedures, but also stem from a poor understanding of normal human lip anatomy. Professor Muluk notes that this ratio should be found in the width of the nose and mouth, as well as the distance between the pupils to the chin compared with the hairline to the pupils. According to scientists from the Kirkkale University’s Faculty of Medicine, the ideal lip ratio is closer to the proportions of Kate Beckinsale and Mila Kunis 1. Surprisingly, the Kardashian-Jenners are not at the forefront of the perfect lip trend. While Kylie Jenner and Amber Rose have iconic pouts, research has determined the exact measurements of the ideal lip ratio. The Perfect Lip Proportions, According to Science


While we all long for the picture-perfect look that has taken over our Instagram feeds, it’s important to understand the ideal lip ratio before going under the needle. With celebrities like Kylie Jenner, Angelina Jolie, and Taylor Swift taking the spotlight, most women are looking to achieve more prominent lips-regardless of how well bigger lips will match their facial features. Whether it’s with lip fillers, overlining the lips with lip liner, or plumping serums, women (and men) around the world are doing everything they can to achieve the perfect lip ratio. In recent years, full, luscious lips have become the trademark of influencers, celebrities, and models.
