Upload one front-facing portrait and the AI face shape detector reads your face shape geometry — jawline, forehead width, cheekbone proportions — to generate a personalized Eyewear Style Matching Report with 4 best-fit frames for your face shape, a try zone, and an avoid zone.
Each face shape pairs with a different frame style. Browse the seven most common face shapes and the frames that fit each one.
Round Face Shape
If your face shape is round with soft cheeks and a curved jaw, sharper rectangular frames cut the curves and add structure. Our face shape glasses tool picks the best glasses for round face geometry — usually a thin wayfarer or slim rectangle in dark tortoise or soft black.
Oval Face Shape
An oval face shape is the most balanced face shape — almost any frame works. The best glasses for oval face shape highlight cheekbones without overwhelming proportions. A slim metal aviator in champagne gold is the safest daily pick.
Square Face Shape
A square face shape has a strong jawline and broad forehead. The best glasses for square face shape soften angles — round and oval acetate frames in warm brown work best. Avoid heavy rectangles that double the angular look.
Heart-Shaped Face
A heart-shaped face shape is wide at the forehead and narrow at the chin. The best glasses for heart shaped face geometry add visual weight at the bottom — bottom-heavy rounded rectangles or soft cat-eye frames in soft black balance the proportions.
Diamond Face Shape
A diamond face shape has high cheekbones, a narrow forehead, and a narrow chin. The best glasses shape for diamond face highlights cheekbones without widening them — cat-eye and soft oval frames in smoke gray are ideal.
Oblong / Long Face Shape
An oblong or long face shape is longer than it is wide. The best glasses for oblong face shape add horizontal width and break vertical length — wide acetate frames in tortoise with decorative temples shorten the visual length.
Inverted Triangle Face Shape
An inverted triangle face shape has a narrow forehead and a wider jawline. The best glasses for inverted triangle face shape add weight at the top with rounded or aviator frames. Light metals in gold or smoke gray balance the geometry without adding heaviness.
