Built for calculator intent
This page focuses on measurable face proportions, so it is different from a pure face shape detector. You can see why the result points toward oval, round, square, heart, diamond, oblong, or triangle.
Face Shape Calculator
Find your face shape with a free measurement-based face shape test. Enter your forehead, cheekbone, jawline, and face length measurements, or use the photo mode when you want an instant AI estimate.
Prefer a photo-based face shape test?
Photo mode uses the same face shape analysis endpoint as the detector page. Use it when you do not want to measure manually, then compare the result with the calculator if you want a second check.
- Use a straight-on portrait with even lighting.
- Keep hair away from the forehead, cheeks, and jawline.
- Avoid wide-angle close selfies, strong filters, sunglasses, and heavy shadows.
Upload a photo to estimate your face shape

Your photo result is most useful when the outline of your forehead, cheekbones, jaw, and chin is visible.
Mixed face shapes are normal
Many people sit between two categories. The calculator shows a primary result and the closest secondary match instead of forcing every face into one rigid label.
How to Measure Your Face Shape
The calculator works best when each measurement is taken from the same straight-on position. Keep the tape or ruler level instead of following the curve of your face.
Measure face length
Start at the center of your hairline and measure straight down to the lowest point of your chin. This number helps separate oval and oblong faces from round and square faces.
Measure forehead width
Measure the widest part of the forehead, usually halfway between the eyebrows and hairline. A wider forehead can point toward heart or oval tendencies.
Measure cheekbone width
Measure from the outer point of one cheekbone to the other. If this is clearly the widest area, the result may lean diamond, oval, or round depending on length.
Measure jawline width
Measure from one jaw angle to the other, or measure from the chin to one jaw angle and double it. A broad or angular jaw often points toward square or triangle.
Face Shapes This Calculator Can Estimate
The test compares your length-to-width ratio, width balance, chin shape, and jawline feel against common face shape patterns.
01
Oval
Oval faces are usually longer than they are wide, with balanced forehead, cheekbone, and jawline proportions.
- Face length is moderately greater than width
- Jawline and chin usually look softly balanced
02
Round
Round faces tend to have similar face length and width, fuller cheeks, and a soft jawline.
- Length-to-width ratio is close
- Jawline feels curved rather than angular
03
Square
Square faces often have similar forehead, cheekbone, and jaw widths with a more defined jawline.
- Width measurements are close together
- Jawline appears broad or angular
04
Heart
Heart faces are usually wider at the forehead or cheekbones and narrower through the jaw and chin.
- Upper face is wider than jawline
- Chin can look narrow or pointed
05
Diamond
Diamond faces are widest at the cheekbones, with narrower forehead and jaw measurements.
- Cheekbones are the widest measurement
- Forehead and jawline taper inward
06
Oblong
Oblong faces are noticeably longer than they are wide, often with straighter side lines.
- Face length is clearly dominant
- Width measurements can be relatively even
07
Triangle
Triangle or pear faces are wider at the jawline than the forehead, giving more visual weight to the lower face.
- Jawline is wider than forehead
- Lower face appears more prominent
Face Shape Calculator vs Face Shape Detector
Both tools answer what face shape do I have, but they are useful in different situations.
| Factor | Calculator | Detector |
|---|---|---|
| Best for | People who want a measurable, explainable face shape test. | People who want the fastest answer from a single photo. |
| Input needed | Face length, forehead width, cheekbone width, jawline width, plus optional chin and jawline cues. | One clear front-facing portrait. |
| Main advantage | Shows ratios and explains why a face shape was selected. | No measuring required and easier for mobile users. |
| Best workflow | Use after measuring from a mirror or photo for a second opinion. | Use first, then confirm with manual measurements if the result feels mixed. |
Tips for a More Accurate Face Shape Test
Small measurement and photo differences can shift the result, especially when your face is between two categories.
Keep measurements straight
Do not wrap the tape around facial curves. Measure straight across each width point so the ratios stay comparable.
Measure twice
If a number changes a lot between attempts, retake it. A small error can move a borderline oval face toward round or oblong.
Clear the outline
Hair, hats, contour makeup, shadows, and tilted selfies can hide the real forehead, cheekbone, or jawline width.
Treat results as guidance
Face shape categories are practical style shortcuts. Your best hairstyle or glasses choice can still depend on features beyond face outline.
Face Shape Calculator FAQ
What measurements do I need for a face shape calculator?
The most useful measurements are face length, forehead width, cheekbone width, and jawline width. Optional chin shape and jawline feel help separate similar categories such as round versus square or oval versus diamond.
How do I know my face shape from measurements?
Compare your face length to your widest width, then check whether the forehead, cheekbones, or jawline is widest. For example, a longer balanced face often points to oval, similar length and width with a soft jaw can point to round, and a cheekbone-dominant face can point to diamond.
Is a face shape calculator more accurate than a photo detector?
Neither is always better. A calculator is more transparent because you can see the ratios, while a photo detector is faster and easier. If the two results disagree, retake your measurements and use a straight-on photo without lens distortion.
Why did I get a secondary face shape?
Many faces share traits from two categories. A secondary result means your measurements are close to another pattern, such as oval-diamond, square-oblong, or round-square.
Can men and women use the same face shape test?
Yes. The measurement logic is based on proportions, not gender. Style suggestions may differ, but the same face length, forehead, cheekbone, and jawline measurements can be used for men and women.
Can hairstyle, weight change, or aging change my face shape result?
They can change how your outline appears. Hair can cover the forehead or jawline, weight changes can affect cheek fullness, and aging can soften the lower face. Bone structure is relatively stable, but visual face shape can shift.
