Face Shape Calculator: Discover Your Face Shape

Your face shape influences hairstyle choices, eyewear fit, and even makeup placement. Knowing whether you have an oval, round, square, heart, or diamond face helps you pick styles that complement your natural proportions instead of fighting them. Our face shape calculator uses four simple measurements plus a feature-sharpness rating to suggest the category that best matches your profile.

How to Measure Your Face

Stand in front of a mirror in a well-lit room with a flexible tape measure or ruler:

Forehead width: Measure across your forehead at its widest point, usually halfway between your hairline and eyebrows.
Cheek width: Measure the distance between the outer corners of your eyes (your widest cheek point).
Jawline length: Measure from the tip of your chin along the jaw to the outer edge of your ear on one side.
Face length: Measure vertically from the center of your hairline to the tip of your chin.

Optionally note whether your features feel soft and rounded or sharp and angular. Face shapes are subjective, so treat the result as a helpful starting point rather than a rigid label.

The Seven Common Face Shapes

Oval: Longer than wide, with a forehead slightly wider than the jaw and prominent cheekbones.
Round: Similar length and width with soft curves and full cheeks.
Oblong (rectangular): Long face with forehead and jaw in near balance along a straight cheek line.
Square: Forehead and jaw of similar width with a strong horizontal jawline.
Triangle: Jaw wider than the forehead, sometimes called a pyramid shape.
Diamond: Cheekbones are the widest point with a narrower forehead and chin.
Heart: Wide forehead tapering to a narrower chin, like an inverted triangle.

Why Face Shape Matters for Style

Stylists often recommend contrasting your face shape: angular glasses on round faces, rounded frames on square faces, and styles that balance a wide forehead or strong jaw. Once you know your shape, pair this tool with our Sunglasses Size Calculator to find frame dimensions that fit both your face width and your proportions.

Frequently Asked Questions

How accurate is a face shape calculator?

Calculators compare your measurements to common proportions, but face shape is partly subjective. Use the result as guidance for glasses and hairstyles, and trust your own eye if a different label feels more accurate.

What is the difference between oval and oblong face shapes?

Both are longer than wide. An oval face usually has a forehead slightly wider than the jaw and softer cheek curves. An oblong face has a longer, straighter cheek line with forehead and jaw closer in width.

What is the difference between round and square face shapes?

Round and square faces are often similar in length-to-width ratio. Round faces have softer curves and rounded jawlines, while square faces have straighter sides and a more angular, horizontal jaw.

Do braces change your face shape?

Braces mainly adjust teeth alignment. They may temporarily make the jaw appear slightly wider or more angular while worn, but they do not permanently change your underlying bone structure or face shape category.

Which glasses suit a heart-shaped face?

Heart-shaped faces look great in frames that add width at the bottom, such as round, aviator, or light-rimmed styles. Avoid heavy decorative tops that emphasize an already wide forehead.

Can I use inches instead of centimeters?

Yes. Select inches in the measurement unit dropdown and enter your values as measured. The calculator converts internally and returns the same face shape result.
