What is the Gonial Angle?

The ideal Jawline in men

A common question we get is what the best jawline angle is. Your jawline angle can make or break your facial appearance, depending on what exactly you consider the jawline angle to be. There are multiple ways and angles with which to measure the jaw. The most common is the gonial angle.
The best jawline angle (gonial angle) is about 120-130 degrees. The best jawline inclination is alignment with a line from the eye’s lateral canthus to the nasal alar (or within 15 degrees from this line).

What is the Gonial Angle?

The mandible is your lower jaw, and the angle refers to the part of your jaw that tapers sharply towards your chin. The gonial angle is the angle of your mandible.
The ideal gonial angle for both men and women ranges from 120-130 degrees. It gives you enough of a prominent look without making you look like a mouthbreather if it is larger. If your gonial angle was less than that range, your face might look way too square.
Men grow more masculine features when they go through puberty because of the increase in testosterone, including a large jaw. So when a man has a defined jaw, especially at the ideal angle, it makes them look more masculine.
There is no exact ideal jaw angle that men should have. However, studies show there was a massive preference for men who had a jaw angle of 130 degrees.
