Face Shape Calculator

Discover your face shape by measuring four key facial dimensions. Understanding your face shape helps you choose the most flattering hairstyles, glasses, and makeup techniques.

How to Measure Your Face

Stand in front of a mirror in good lighting. Use a flexible measuring tape or ruler. Pull your hair back to clearly see your face outline.

  • Forehead Width: Measure across your forehead at its widest point, typically halfway between your hairline and eyebrows.
  • Cheekbone Width: Measure across your cheekbones at their widest point, usually just below the outer corners of your eyes.
  • Jawline Length: Measure from the tip of your chin to below your ear, where your jaw angles upward.
  • Face Length: Measure from the center of your hairline straight down to the tip of your chin.
How It Works

Face Shape Determination Formula

Our calculator analyzes the ratios between your facial measurements to determine your face shape. The algorithm considers:

  • Face Length to Width Ratio: Compares face length to the widest measurement (forehead, cheekbones, or jawline).
  • Widest Feature: Identifies whether your forehead, cheekbones, or jawline is the widest part of your face.
  • Feature Sharpness: Adjusts the determination based on whether your features are angular or rounded.

Formula Logic:

ratio = faceLength / max(foreheadWidth, cheekboneWidth, jawlineWidth)
widestFeature = argmax(foreheadWidth, cheekboneWidth, jawlineWidth)

if ratio > 1.5:
  if widestFeature == cheekbones and sharpness == sharp:
    faceShape = "Diamond"
  else:
    faceShape = "Oblong"
else if ratio < 1.1:
  if sharpness == sharp:
    faceShape = "Square"
  else:
    faceShape = "Round"
else:
  if widestFeature == forehead:
    faceShape = "Heart"
  else if widestFeature == jawline:
    faceShape = "Triangle"
  else if widestFeature == cheekbones:
    faceShape = "Oval" or "Diamond"
  else:
    faceShape = "Oval"
      

This is a simplified representation. The actual algorithm uses more nuanced thresholds and considers multiple factors simultaneously.
