How to Use the Calculator
To get an accurate result, you will need a flexible tape measure. Avoid using a stiff metal construction tape measure as it cannot curve around your face properly.
Preparation
- Pull your hair back: Ensure your hairline and ears are completely visible.
- Good lighting: Stand in front of a well-lit mirror.
- Keep it flat: Try to keep the tape measure relatively flat against your skin.
Measurements
- Forehead: Measure across the widest part (eyebrow arch to arch).
- Cheekbones: Measure from the sharpest point of one cheekbone to the other.
- Jawline: Measure from chin tip to below ear, then multiply by 2.
- Face Length: Measure from center hairline to chin tip.
Visual Face Shape Guide
Understanding your geometry is the first step. Here is a detailed breakdown of the 6 primary face shapes used in dermatology and styling.
Oval Shape
Longer than wide with cheekbones slightly wider than jaw and forehead. Rounded jawline. Often considered the "universal" shape.
Round Shape
Circular face where cheekbones are roughly the same width as the length. Soft features without sharp angles.
Square Shape
Forehead, cheekbones, and jawline are all roughly the same width. Defined by a strong, sharp, angular jawline.
Heart Shape
Widest at the forehead, tapering down to a pointed chin. often features a widow's peak hairline.
Diamond Shape
High, dramatic cheekbones are the widest point. Forehead and jawline are narrower. The rarest face shape.
Oblong Shape
Noticeably longer than it is wide. Forehead, cheeks, and jaw are similar in width, creating a rectangle with rounded corners.
Styling Advice
The goal of styling is usually to create the illusion of an Oval shape (balanced proportions).
Best Glasses
Contrast is key. If your face is round, choose square frames. If your face is angular (Square, Diamond), choose round or oval frames to soften the lines.
Best Hair Styles
Create balance. Wide foreheads (Heart) benefit from side-swept bangs. Narrow jaws (Heart, Diamond) look great with chin-length bobs that add volume at the bottom. Long faces (Oblong) benefit from waves and curls to add width.
