Summary

Gemma Arterton's Jaw Slope, the angle where her upper and lower jaw meet, measures 135.7° and scores 6.1, sitting below its ideal range of 142.0 to 144.5°. The measurement assesses how well-defined that angle is: a sharper angle produces a strong, structured jawline, while a more rounded angle gives a softer, gentler look. Her value sits closest to those of Sigourney Weaver at 135.9°, Joey King at 135.6° and Paulina Porizkova at 135.5°. Among the women on the wiki she stands among the lowest, while 25% of them measure inside the ideal range, and across the full wiki the highest reading belongs to Doja Cat at 155.8°.
