Summary

Bonnie Blue's Upper Forehead Slope measures 11.0° and scores 8.6, placing it above its 7.0 to 9.0° ideal range. Her value matches Winter (aespa) and Kristin Kreuk (Smallville) exactly, and sits close to Huh Yunjin at 11.1°. The measurement evaluates how much the upper forehead slopes backward from the rest of the forehead, and a more sloped upper forehead can make the upper face appear more feminine. Her value is higher than 75% of the women on the wiki, while 20% of them measure inside the ideal range, and the wiki's extremes run from Zendaya at 0.5° to Sadie Sink at 24.1°.
