If you have ever asked, “What is my face shape?” this calculator gives you a practical, data-driven answer in under a minute. Enter four simple measurements and the tool will estimate your likely face shape: oval, round, square, rectangle, heart, diamond, or triangle.
Find Your Face Shape
Use the same unit for every field (cm or inches). For best results, measure in front of a mirror and keep the tape level.
- Forehead Width: left temple to right temple at the widest point.
- Cheekbone Width: widest point under each outer eye corner.
- Jawline Width: from one jaw angle to the other, across the chin.
- Face Length: center hairline to bottom of chin.
How this facial shape calculator works
This tool compares your horizontal proportions (forehead, cheekbones, jawline) and your vertical proportion (face length). Most face shape systems use these exact dimensions, because each shape has a recognizable pattern. For example, a heart face usually has a wider forehead and narrower jaw, while a rectangle face tends to have similar widths but noticeably greater length.
The calculator does not use a single strict rule. Instead, it assigns weighted scores to multiple patterns and then chooses the strongest match. That approach is more realistic for real faces, because many people fall between categories.
How to measure accurately
1) Forehead width
Measure the widest part of your forehead, usually halfway between eyebrows and hairline. Avoid measuring too low near the brow ridge.
2) Cheekbone width
Place the tape at the most prominent point below each outer eye. Keep it straight and level; angling the tape downward can distort results.
3) Jawline width
Measure from one jaw angle to the other in a straight line across the front of your chin. Keep your jaw relaxed and mouth closed.
4) Face length
Measure from your center hairline to the bottom of your chin. If your hairline is uneven, estimate your natural line as closely as possible.
Face shape categories explained
- Oval: face length is greater than width, with gently tapered jaw and balanced forehead/cheekbone proportions.
- Round: width and length are relatively close, with softer curves and less angular jawline appearance.
- Square: forehead, cheekbones, and jawline are similar in width, with a broader, stronger jaw area.
- Rectangle (Oblong): similar widths like square, but with a clearly longer face.
- Heart: wider forehead, narrower jawline, often with prominent upper-face width.
- Diamond: cheekbones are the widest point, while forehead and jawline are narrower.
- Triangle (Pear): jawline is widest and forehead is narrower.
How to use your result
Knowing your face shape can help with practical style decisions:
- Haircuts: balance width and length visually (for example, add side volume for long faces or top height for wide faces).
- Glasses: choose frames that counter your strongest facial angles or proportions.
- Beard styling: shape facial hair to lengthen, soften, or sharpen your outline.
- Makeup placement: contour and highlight based on your natural geometry instead of trends.
Important limitations
No calculator can fully capture three-dimensional anatomy, muscle tone, body composition shifts, or hairstyle effects. Treat this as a strong starting point, not a medical or biometric classification. If your top two categories are close, both may be useful for style decisions.
Quick FAQ
Can I use inches instead of centimeters?
Yes. Use any unit, as long as all four measurements use the same unit.
Why did I get a shape different from what apps told me?
Many apps rely on camera angles and lighting, which can distort proportions. Manual measurements are often more consistent.
Do men and women use different shape rules?
The proportional framework is the same. Style recommendations may differ, but the geometric categories do not.
