The upper forehead slope describes how far the upper forehead tilts backward from the rest of the forehead. Avril Lavigne measures 7.5° on this angle, scoring 10.0, which places her inside the ideal range of 7.0 to 9.0° and higher than 35% of the women on the wiki. Shalom Harlow and Millie Bobby Brown share her exact value of 7.5°, while Sadie Sink sits at the highest end of the wiki at 24.1° and Zendaya at the lowest at 0.5°. A gentle slope creates a natural, balanced appearance, and Avril's Browridge Inclination Angle adds further context to her upper face. For the full picture, see Avril's full Harmony breakdown.
