Upper vs lower width
Forehead and jaw are usually closer in width than on heart or triangle faces.
Square face shape guide
A face with a broad forehead, a strong jaw, and similar width through the upper and lower face.
Square faces combine balanced width with more visible angles. The jaw corners tend to be defined, and the forehead, cheekbones, and jaw may appear relatively close in width.
Use a straight-on image with a neutral expression. Pull hair away from the outline and compare proportions, not millimeters taken from an uncalibrated photo.
Forehead and jaw are usually closer in width than on heart or triangle faces.
A visible corner is more important than absolute jaw width.
The face is balanced or moderately long, but not dominated by vertical length.
Choose whether to soften the angles with curves or emphasize the strong structure with deliberate geometric styling.
Curved lenses can soften a strong jaw, while lighter construction prevents the glasses from competing with an already defined outline.
Soft texture and offset lines create contrast with the angular outline; clean geometric cuts can instead be used when the goal is to emphasize it.
A face with a broad forehead, a strong jaw, and similar width through the upper and lower face. Compare face length, forehead, cheekbones, jaw width, and jaw curvature together rather than relying on one feature.
Round frames, Oval frames, Thin metal frames, Soft aviators are useful starting points. Frame width and lens depth still need to be checked on your own photo.
Soft waves, Layered shoulder-length cuts, Side-swept bangs, Textured pixie with movement are practical options. Texture, hair type, maintenance, and personal preference matter as much as face shape.
