Lip Math: Which Lip Ratio is Right for You?

There’s boy math. There’s girl math. But did you know there’s also lip math? In fact, there’s actually a ratio for perfect lips. It’s called the golden ratio. In it, the bottom lip is ideally 1.618 times larger than the top lip. According to the golden ratio: Lips should be 1.618 wider than the width of the nose and top lip. The info comes from a study in 2017 and for many, many years that golden rule held true. 

Because of the golden ratio, the trend was for the bottom lip to be larger than the top lip. These proportions resulted in the most natural-looking lip. But it’s safe to say with the ever-evolving technology surrounding injectables, times are changing. And so are lips. 

As luck would have it, not all full, lush lips are created equal. Just look at Angelina Jolie, Kylie Jenner and Sara Sampaio. A little plump here and there can help you achieve the lip look you are going for. And these days, women (and men) are tossing rules—golden and otherwise— to the wind and looking for the most prominent lips for their face. And many times that means disregarding how well those new lips match their features. 

When 2020 happened, with it came the era of the 50/50 lip. It’s also known as the “perfectly proportioned” lip. In it, both lips are equally symmetrical. Why should the bottom lip have all the fun? Why not make the most of both lips? The trend resulted in super pouty pouts, fabulous puckers and lips for days. 

And now, three years later, there’s yet another flip in lip trends. This time, the trend is leaning toward a bigger top lip and a smaller bottom lip. It’s a proportion that turns the natural look literally upside down, but it’s a bold new trend. 

So what do all of these proportions mean for you? It depends on what look you are going for. It could also depend on your other features, if that’s what you’re going for. It depends on how many times you are willing to revisit to get the shape and plump you want. Remember, full lips don’t happen overnight. It takes time and multiple sessions.
