The Face Shapes Explained

Oval
Oval

Round

Key Features: Width ≈ length, full cheeks, soft jaw curves.

Square
Square

Key Features: Equal widths (forehead/cheekbones/jaw), angular jaw, width ≈ length.

Heart

Key Features: Forehead widest, high cheekbones, narrow chin.

Oblong
Oblong

Key Features: Length >> width, straight sides, minimal taper.

Diamond
Diamond

Key Features: Cheekbones prominent, narrow forehead, pointed chin. 

Description: With a narrower forehead and jawline, the cheekbones are the most prominent feature. Adding volume at the temples and chin, combined with oval eyewear frames, creates excellent balance.

Triangle

Key Features: Jaw widest, narrow forehead, bottom-heavy.

Key Features: Forehead widest (Broad forehead), tapering cheekbones (Gradual taper), narrow/pointed chin (Narrow jawline). 

Description: Features a prominent forehead that serves as the widest point of the face, narrowing consistently toward a delicate jaw and pointed chin. To create balance, it is best to add volume near the jawline with textured layers or choose eyewear with bottom-heavy frames to offset the width of the upper face.
