Angularity
Angularity: how bone definition is assessed
3 min read · Updated October 4, 2026
Angularity is about how much of your bone structure shows through the soft tissue: sharp cheekbones, a crisp jawline and chin, lean cheeks and a clean line under the chin. Two faces with the same bone shape can look very different here depending on leanness.
How it differs from Harmony
Harmony measures proportion with landmarks. Angularity is about visual definition, which landmarks can't capture, so it is graded by an AI model from the photo. It is also the pillar most responsive to things you can change, such as body fat, posture and the lighting you shoot in.
What moves angularity
Angularity is the pillar most affected by things other than bone. Leanness is the biggest factor, because the same cheekbone or jaw looks sharper under less soft tissue. Posture and head position come next: a forward head and a lowered chin create fullness under the jaw that a level, lifted posture doesn't. Lighting is the third, since light from slightly above or to the side casts the shadows that make a contour readable, while flat front light smooths it away.
Hydration, sleep and salt change how puffy the face looks from one day to the next, which is why the same person can score differently across a week. That makes angularity worth tracking over several scans rather than reading from one.
Why landmarks can't measure it
Two faces can have identical landmark positions, and so identical outlines, and still look very different in definition. What separates them is shadow, contour and soft-tissue thickness, which are visual qualities of the photo, not points on a mesh. That's why this pillar is graded by an AI model from the photo against people of the same sex.
Reading your five rows
Your report lists five Angularity rows, and they fall into two natural pairs. Cheekbone Prominence and Cheek Leanness go together: lean cheeks make the cheekbones visible, so if both are low, leanness and lighting are the first things to look at.
Jaw Definition, Chin Definition and Submental Definition describe the lower face from the ear down to the neck, and they tend to move together because the same posture and soft tissue affect all three. A single low row is worth rechecking with a second photo before you draw conclusions. If all five are low, it more likely reflects overall leanness or the lighting than any one feature.
Questions about angularity
Can I improve angularity without changing my bones?
Often, yes. Because the pillar reflects soft tissue as much as bone, changes in leanness, posture and lighting commonly change the result without anything about your skeleton changing.
Does lighting really matter that much?
Yes. The same face in flat window light and in light from above can read as very different in definition. Keep your light and angle the same when comparing scans.
Why is it scored against my sex?
Typical fullness and definition differ between men and women, so a score only makes sense against the norm for the sex you selected.
Why is chin definition hard to judge from the front?
Chin projection is easiest to see in profile. A front photo shows the outline and soft tissue, but only part of the picture, so treat that row with extra caution.
Measurements
