Face Shape Calculator
Enter your face measurements using the same unit (cm or inches). This tool estimates your likely face shape from proportions.
Tip: For better accuracy, take each measurement twice and use the average.
What is a face shape calculator?
A face shape calculator uses basic facial proportions to estimate which shape category your face most closely matches. The most common categories are oval, round, square, rectangle (oblong), heart, diamond, and triangle (pear). While no person fits a category perfectly, this method can help with practical choices like hairstyles, glasses, makeup contouring, and beard styling.
How this calculator works
This tool compares four measurements:
- Forehead width: the widest point across your forehead.
- Cheekbone width: distance across the highest points of your cheekbones.
- Jawline width: width across the jaw at its broadest point.
- Face length: from the center of your hairline to the bottom of your chin.
From these numbers, the calculator identifies the widest facial zone and checks how long your face is relative to width. The resulting pattern maps to a likely face shape.
How to measure your face correctly
1) Forehead width
Look straight into a mirror and place a soft measuring tape from one side of the forehead to the other at the widest horizontal point, typically between the hairline and eyebrows.
2) Cheekbone width
Measure from the most prominent part of one cheekbone to the other. Keep the tape straight and level.
3) Jawline width
Measure from one side of your jaw to the other at the widest area near the angle of the jaw. If needed, measure one side from chin to jaw angle and double it.
4) Face length
Measure vertically from the center of your hairline down to the tip of your chin. Keep your head upright in a neutral position.
Understanding each face shape
Oval
Usually the face is longer than it is wide, with cheekbones often slightly wider than forehead and jawline. The jaw is gently rounded. Many styles suit this proportion.
Round
Face length and width are close, and facial lines are softer with less angular definition. The cheeks may appear fuller.
Square
Forehead, cheekbones, and jawline are similar in width, and the jaw appears more defined. Length and width are often relatively close.
Rectangle (Oblong)
The face is noticeably longer relative to width while forehead, cheeks, and jaw remain fairly balanced.
Heart
The forehead is widest, cheekbones are moderate, and the jawline narrows toward the chin. This can produce a top-heavy visual balance.
Diamond
Cheekbones are the widest feature, while forehead and jawline are narrower. Often paired with a more tapered chin area.
Triangle (Pear)
The jawline is widest compared with forehead and cheekbones, creating a lower-heavy facial structure.
How to use your result
Haircuts
- Round: add height at the crown and keep sides tighter to create length.
- Square: textured layers or softer edges can balance angularity.
- Heart: chin-length volume helps balance a wider forehead.
- Rectangle: avoid excessive top height if you want less vertical emphasis.
Glasses
- Round faces: angular frames can add structure.
- Square faces: round/oval frames soften strong lines.
- Heart faces: lighter lower rims can balance proportions.
- Diamond faces: browline and oval frames often complement cheekbone emphasis.
Facial hair and contouring
Beard shape and makeup contour can visually shift balance. For example, adding width at the jaw (through beard fullness or contour placement) can offset a wider forehead, while reducing side volume can slim a wider lower face.
Important limitations
Face shape categories are approximations, not strict labels. Bone structure, body composition, hairstyle, age, and camera angle can all change perception. If your result lands between two categories, that is completely normal. In practice, combining guidance from both shapes usually works best.
Quick FAQ
Is this medically accurate?
No. It is a style-oriented estimation tool based on visible proportions.
Can I use inches instead of centimeters?
Yes. Ratios are what matter, so any unit works as long as all measurements use the same unit.
Why did I get a shape that feels wrong?
Small measurement errors can change the output. Re-measure carefully, average multiple readings, and consider that many people sit between categories.
