Face Score is the 0–100 number you see in The Lab before every Face Rank match. It is not a beauty verdict, it is a weighted average of five facial proportion metrics that are well known in facial-analysis research, computed entirely in your browser from a face-landmark mesh.
The five sub-scores
1. Symmetry (28% weight)
We reflect each facial landmark across the vertical axis through the bridge of your nose and compare it to its mirror partner. Closer = higher symmetry. Symmetry is the heaviest input because it is one of the most consistently reproducible measurements — lighting and angle barely change it.
2. Balance (22% weight)
Two classic proportion rules: "thirds" (forehead to brow, brow to nose, nose to chin should be roughly equal) and "fifths" (the face is about five eye-widths wide). Big deviations cost points; small ones don’t.
3. Jawline (18% weight)
We approximate the gonial angle (the angle the jaw makes at the chin) and combine that with overall face width-to-height ratio. A defined, slightly narrow jaw scores higher; broad or very rounded faces score lower, but you can move the score by 5–10 points just with better posture and chin-down angle.
4. Skin (16% weight)
From a cheek crop of the video frame, we compute color uniformity (standard deviation across pixels). Even tone scores higher. This is the metric most affected by lighting — soft, even light improves it dramatically.
5. Eye Angle (16% weight)
The slope from the inner eye corner to the outer corner. A neutral or slightly positive tilt is the canonical "ideal" the internet has anchored on. We reward a small positive tilt and don’t penalize neutral.
How the overall is calibrated
Raw weighted averages would cluster everyone in the 50–70 range, which feels meaningless. So we pass the weighted sum through a soft sigmoid that stretches scores toward the extremes. The result is a clearer signal of where you actually sit, but not a harsh number that punishes most players.
Important: what Face Score is NOT
- It is not a beauty verdict. Facial proportions are one signal; expression, voice, presence, lighting and posture matter at least as much in a 15-second match.
- It is not ELO. Your Face Score gives you a private baseline — you only climb the ladder by winning matches.
- It is not uploaded. The model runs on-device. Only the five integers + the W/L of each match are ever sent to our server.
