Find Your Face Shape From Four Measurements
This face shape detector identifies your face shape from four simple measurements — forehead width, cheekbone width, jawline width, and face length — and tells you which of seven shapes fits your features. It is built for anyone choosing a flattering hairstyle, glasses frame, or makeup look but unsure where to start.
Enter your numbers in centimeters or inches and the tool analyzes the ratios between them to classify your face as oval, round, square, oblong, heart, diamond, or triangle. You then get tailored hairstyle, glasses, and makeup suggestions, plus a reference chart that highlights your matching shape.
How to Detect Your Face Shape
Measure four areas
With a flexible measuring tape and a mirror, measure your forehead width at its widest point, your cheekbone width just below the outer corners of your eyes, your jawline from chin to ear and then doubled, and your face length from hairline to chin.
Pick your unit
Choose centimeters (cm) or inches (in) with the toggle. If you switch units after typing values, the tool converts them automatically so you never re-enter anything.
Enter your measurements
Type your four numbers into the A, B, C, and D fields. The color-coded face diagram shows exactly where each measurement is taken, matching the marker on every input.
Detect your shape
Click Detect Face Shape (or press Enter). You instantly see your shape with a description, a summary of your measurements, hairstyle, glasses, and makeup recommendations, and your shape highlighted in the reference chart.

Frequently Asked Questions
How do I find my face shape?
Measure your forehead width, cheekbone width, jawline width, and face length, then enter them here. The tool compares the ratios between those measurements and tells you which of the seven face shapes matches your features.
What are the main face shapes?
This detector recognizes seven: oval (balanced, slightly longer than wide), round (width and length nearly equal, soft curves), square (strong jaw, similar widths), oblong (noticeably longer than wide), heart (wide forehead, narrow chin), diamond (wide cheekbones, narrow forehead and jaw), and triangle (jawline wider than forehead).
Which measurements determine my face shape?
Four: forehead width, cheekbone width, jawline width, and face length. The tool studies how length relates to width and how the forehead, cheekbones, and jaw compare to each other to classify your shape.
How do I know if my face is oval or round?
The key difference is length versus width. A round face is close to equal in length and width with soft, curved lines, while an oval face is a bit longer than it is wide with gently balanced features. Entering your measurements removes the guesswork — the ratios decide which one fits.
What if my face shape seems between two categories?
Many people share traits of two or more shapes. If your measurements fall near a boundary, try the recommendations from both shapes and keep what suits you. Face shape is a styling guideline, not a strict rule.
Why is my jawline measurement doubled?
The jawline width is the full distance from one side of the jaw to the other. Because that is awkward to measure directly across, you measure from your chin to below one ear and multiply by two to get the total width.
Can men use this tool?
Yes. Face shape detection works the same way regardless of gender, and the hairstyle and glasses suggestions apply to everyone. The makeup section covers general contouring principles that anyone can use or skip.
Do I measure in centimeters or inches?
Either works — use whichever your measuring tape shows. The tool converts internally, and you can switch between cm and inches at any time without re-entering your numbers.
