If you want to identify your face shape using actual numbers (not just guesswork in a mirror), this calculator gives you a practical estimate based on facial width and length measurements. Enter your values below, then read the guide to understand how to measure correctly and how to interpret your result.
Face Shape Calculator
Use the same unit for every measurement (cm or inches). For best results, measure 2–3 times and use your average.
How this face shape calculator works
The calculator compares your four core measurements: face length, forehead width, cheekbone width, and jawline width. It then evaluates key ratios and pattern relationships to classify your most likely shape:
- Oval: face length is notably longer than width, with a gently narrower jawline.
- Round: width and length are close, with softer transitions.
- Square: similar widths across forehead, cheeks, and jaw; shorter to medium face length.
- Rectangle/Oblong: similar widths, but significantly longer face length.
- Heart: broader forehead, narrower jaw/chin area.
- Diamond: widest at cheekbones, with narrower forehead and jaw.
- Triangle (Pear): jawline wider than forehead and often wider than cheekbones.
How to take accurate measurements
You only need a flexible measuring tape, mirror, and good lighting. Keep your face relaxed and look straight ahead.
1) Face length
Measure from the center of your hairline to the bottom of your chin. If your hairline is uneven, use your natural mid-hairline point.
2) Forehead width
Measure across the widest part of your forehead, usually halfway between your eyebrows and hairline.
3) Cheekbone width
Measure from the highest point of one cheekbone to the highest point of the other. Keep the tape lightly touching the face without bending around the head.
4) Jawline width
Measure from one jaw corner (below the ear) to the other across the chin, or measure one side and double it if that is easier and more consistent.
5) Optional jaw angle
If you know your approximate jaw angle, add it. Lower angles often look more angular (square), while higher angles tend to appear softer (round).
Understanding your result
Your result includes a likely shape, confidence level, and brief style guidance. Confidence is higher when your measurements strongly match one pattern and lower when your proportions are balanced across multiple categories.
Common blended patterns
- Oval + Heart: longer face with slightly wider forehead.
- Round + Square: similar widths with only mild jaw definition differences.
- Diamond + Oval: prominent cheekbones with moderate face length.
Practical uses for face shape measurements
- Choosing eyeglass frame geometry
- Selecting haircut volume and length placement
- Evaluating beard and neckline balance
- Comparing contour and makeup structure for proportional harmony
Tips to improve measurement accuracy
- Measure each dimension at least twice.
- Use a non-stretch fabric tape, not a rigid ruler.
- Keep tape straight for width measurements; do not wrap around head curvature.
- Record values to one decimal place for better ratio precision.
- Take measurements with neutral expression and natural posture.
Frequently asked questions
Can I use inches instead of centimeters?
Yes. The calculator uses ratios, so the unit does not matter as long as all measurements use the same unit.
Why does my result change slightly when I remeasure?
Small placement differences can shift ratios, especially if your features are near category boundaries. Average multiple measurements for stability.
Is one face shape better than others?
No. Face shape is descriptive, not a quality ranking. The goal is to understand proportions so styling choices become easier.
Can my face shape change over time?
Yes, somewhat. Weight changes, age-related soft tissue changes, and hairstyle choices can alter the way shape appears.
