Measure horizontally across your forehead, cheekbones, and jawline. For face length, measure vertically from your hairline to the bottom of your chin.

Your forehead, cheekbones, jawline, and face length can tell you a lot about the overall shape of your face. The Face Shape Calculator compares these measurements, along with the appearance of your chin, to find the face shape that most closely matches your features.

What Does the Face Shape Calculator Measure?

Face shape is not determined by a single measurement. What matters more is how different parts of your face compare with one another.

The Face Shape Calculator looks at whether your face is longer than it is wide, which part of your face is the widest, how similar your forehead and jawline widths are, and whether your chin appears rounded, moderate, or pointed.

Using these details, the calculator compares your proportions with common face-shape categories such as oval, round, square, heart, diamond, and longer face shapes.

These categories are mainly used for styling purposes, such as choosing hairstyles, glasses, or makeup styles. They should not be considered medical or anatomical classifications.

How to Measure Your Face Shape

Getting accurate measurements will give you a more useful result. Before you start, pull your hair away from your face and look straight ahead. A flexible measuring tape usually works best.

Try to keep the tape straight rather than following the natural curves of your face. You can measure in either inches or centimeters, but make sure you use the same unit for every measurement.

Measurement	How to Measure
Forehead width	Measure straight across the widest part of your forehead, usually somewhere between your eyebrows and hairline.
Cheekbone width	Measure horizontally between the most prominent points of your cheekbones.
Jawline width	Measure straight across the widest part of your lower jaw. Do not follow the curved edge of the jaw.
Face length	Measure from the center of your hairline straight down to the lowest point of your chin.
Chin appearance	Choose the option that best describes your chin as rounded, moderate, or pointed.

It is a good idea to take each measurement twice. Even a small difference in where you place the measuring tape can change the result, especially when two measurements are very close.

How to Use the Face Shape Calculator

1. Measure your forehead, cheekbones, jawline, and face length.
2. Enter the four measurements into the calculator using the same unit.
3. Choose the option that best describes your chin.
4. Click Calculate to see your likely face shape and proportion details.
5. Check the “Why this result” section to see which features contributed to your result.

If two or more of your measurements are almost the same, try measuring them again. This can help prevent a slightly misplaced measuring tape from affecting your result.

How Does the Face Shape Calculator Work?

There is no single formula that can perfectly determine everyone’s face shape. Faces naturally vary, and many people have features that fall somewhere between two common categories.

For this reason, the calculator considers several measurements and proportions instead of relying on one number.

One of the main proportions it uses is the relationship between face length and cheekbone width:

Length-to-width ratio = face length ÷ cheekbone width

The calculator also checks which measurement is the widest and how your forehead width compares with your jawline.

The table below gives a simple overview of the general patterns commonly associated with each face shape.

Face Shape	Common Proportion Pattern	Other Common Features
Oval	Face is usually longer than it is wide	Balanced widths with a softer taper toward the chin
Round	Face length and width tend to be relatively close	Softer jawline and rounded chin
Square	Forehead and jawline are often similar in width	Stronger or more angular jaw
Heart	Forehead is generally wider than the lower face	Jaw narrows toward the chin
Diamond	Cheekbones are often the widest measurement	Forehead and jawline are narrower
Longer face	Face length is noticeably greater than its main width	Features may appear more vertically elongated

These are general patterns rather than strict rules. Two people with the same face-shape result can still look quite different.

The Face Shape Calculator therefore looks at your measurements together and gives you the closest overall match instead of deciding your shape from one feature alone.

Face Shape Calculation Example

For example, imagine that you enter these measurements:

Input	Example Value
Forehead width	14.5 cm
Cheekbone width	15.2 cm
Jawline width	13.2 cm
Face length	19 cm
Chin appearance	Rounded

The length-to-width ratio would be:

19 ÷ 15.2 = 1.25

Looking at the measurements, a few things stand out:

Observation	What the Measurements Show
Overall proportion	The face is longer than it is wide
Widest area	Cheekbones at 15.2 cm
Lower face	Jawline is narrower at 13.2 cm
Length-to-width ratio	1.25
Chin	Rounded

Instead of using the 1.25 ratio by itself, the Face Shape Calculator considers all of these details together with the selected chin appearance before choosing the closest face-shape category.

This is important because a ratio alone cannot describe the complete shape of a face.

What If Your Face Matches More Than One Shape?

That is completely possible. Real faces do not always fit neatly into one category.

For example, you may have the overall proportions commonly associated with an oval face but a stronger, more angular jaw. Someone else might have a wider forehead associated with a heart-shaped face while also having prominent cheekbones commonly seen in diamond-shaped faces.

If your measurements are close to the boundary between two categories, think of your result as a general description of your proportions rather than a strict label.

Other factors can affect how your face appears as well. Your hairline, facial soft tissue, age, expression, camera angle, and even the way you take your measurements can influence the result.

When your measurements are close, pay particular attention to the calculator’s explanation of why it selected a particular shape.

Important Things to Know About Your Result

The Face Shape Calculator is designed to provide an approximate face-shape category for styling and general information.

Keep these limitations in mind:

• Your result is an estimate based on the measurements you provide.
• It is not a medical, biometric, forensic, or identity assessment.
• The calculator does not measure facial symmetry or attractiveness.
• Small differences in your measurements may change the result.
• Your personal preferences may be more important than your face-shape category when choosing glasses, hairstyles, makeup, or facial hair.

If you are interested in other proportion-based tools, you can try the Body Shape Calculator or Bikini Calculator. If you are planning to grow your hair for a particular hairstyle, the Hair Growth Calculator may also be useful.

Sources and Method Background

The calculator’s measurement approach is informed by published research on facial dimensions and anthropometric measurement methods:

Use Your Face Shape as a Starting Point

Your calculated face shape can be useful when exploring hairstyles, glasses, makeup, or other styling choices, but it does not need to define what works for you.

Small differences in camera angle, expression, hairstyle, or measuring position can change how your proportions appear. For more consistent measurements, look straight ahead with a neutral expression, keep the measuring tape level, and measure again if two values are particularly close.

Most importantly, remember that many faces combine characteristics from several categories. Use your result as a starting point for exploring different styles rather than treating it as a fixed label.
