What Is Facial Harmony?
Facial harmony describes how well your features sit in proportion with each other. Surgeons, orthodontists, and beauty filter engineers all work with a shared set of measurements — angles, distances, and ratios — to assess balance in a face.
The idea is not about achieving a single "perfect" number. It is about understanding where your measurements fall relative to the ranges that clinical studies treat as balanced, and then using that information the way you choose. Some people track changes from orthodontic work. Others satisfy a curiosity about how the golden ratio applies to their own face.
This calculator measures six key metrics that together give a broad picture of facial proportion. Each one is scored on a 0–100 scale and compared to sex-aware balanced ranges where applicable.

How the Facial Harmony Calculator Works
Using the tool takes about two minutes. Choose between Photo mode (upload a face photo and click the landmark points) or Manual mode (type angles you measured yourself). Both methods use the same scoring engine and produce the same type of result.
Upload a photo
Take a side profile for jaw and nose angles, and a front-facing shot for eyes and the golden ratio. Stand 5+ feet away and zoom in to avoid lens distortion.
Tap landmark points
The tool walks you through each measurement. Click the anatomical points it highlights — like the corner of your jaw or the inner edge of your eye — and it plots them on the image.
Review your scores
Every angle gets a 0–100 score based on how close it sits to the balanced range. A circular gauge shows your overall harmony score at a glance.
Save and compare
Each result is stored locally with the date. Tick any two saved results to see a side-by-side comparison with per-angle deltas. Re-measure after changes and track the trend.
How to Check Facial Harmony: A Step-by-Step Guide
Each measurement asks you to click a small set of points on your photo. The calculator highlights where to click and connects the dots automatically. Here is what each point means and where to find it on your face, so you know exactly what you are clicking before you click it.
Jawline (Gonial Angle)
Side profileThis one needs a side profile photo. You are marking the curve of the jaw from the ear to the chin, so the angle between those two lines can be measured.
- 1.Click the Top of jaw near the ear (condylion). This sits just below your earlobe, where the jawbone hinges.
- 2.Click the Jaw corner (gonion). The sharpest bend in your jawline, where the back edge turns into the bottom edge.
- 3.Click the Tip of chin (menton). The lowest point of your chin in profile.
Nose to Lip (Nasolabial Angle)
Side profileThis measurement also needs a side profile. It captures the angle where the bottom of the nose meets the top of the upper lip. It is one of the few angles with a different balanced range for men and women.
- 1.Click the Base of the nose (columella). The soft tissue strip between the nostrils, right above the upper lip.
- 2.Click the Point under the nose (subnasale). Where the nose ends and the upper lip skin begins.
- 3.Click the Upper lip edge (labrale superius). The most forward point of your upper lip.
Eye Angle (Canthal Tilt)
Front-facingThis one uses your front-facing photo. Only two points are needed, since canthal tilt is simply the line between the two corners of one eye.
- 1.Click the Inner eye corner (medial canthus). Where your eye meets the bridge of your nose.
- 2.Click the Outer eye corner (lateral canthus). Where your eye meets your temple.
Forehead to Nose (Nasofrontal Angle)
Side profileThis needs a side profile. It measures how the forehead transitions into the nose, which surgeons use to judge whether the nose bridge sits high or low relative to the brow.
- 1.Click the Mid forehead (glabella). The smooth area just above and between your eyebrows.
- 2.Click the Deepest point at top of nose (nasion). The small dip where your forehead ends and your nose bridge starts.
- 3.Click the Bridge of the nose (rhinion). The point partway down the nose where the bone ends and the cartilage begins.
Lip to Chin (Mentolabial Angle)
Side profileThis measurement, taken from a side profile, looks at the fold between your lower lip and chin. It is a good indicator of chin projection.
- 1.Click the Lower lip edge (labrale inferius). The most forward point of your bottom lip.
- 2.Click the Deepest fold below lip (mentolabial sulcus). The crease between your lower lip and chin.
- 3.Click the Tip of chin (pogonion). The most forward point of your chin in profile.
Length to Width (Golden Ratio)
Front-facingThis needs a front-facing photo and four points instead of three, since it compares the full height of your face against the full width.
- 1.Click the Hairline center (trichion). The midpoint of your hairline, directly above the center of your forehead.
- 2.Click the Tip of chin (menton). Same point used in the jawline measurement.
- 3.Click the Left cheekbone edge. The widest point of your face on the left side.
- 4.Click the Right cheekbone edge. The widest point of your face on the right side.
A quick tip: the jawline, nose to lip, forehead to nose, and lip to chin measurements all need a clean side profile. The eye angle and length to width measurements need a front-facing shot. Marking profile points on a front-facing photo, or the other way around, is the most common reason people end up with a low confidence score.
The Six Measurements That Decide Facial Harmony
Each measurement targets a specific feature. The balanced ranges come from aesthetic and orthodontic literature — the same benchmarks surgeons use when planning procedures.
Gonial Angle
Jawline
The angle of the lower jaw measured at the corner below the ear. Lower reads sharper and more square, higher reads softer and rounder.
Nasolabial Angle
Nose to lip
The angle between the base of the nose and the upper lip. A slight upward tilt usually reads more feminine and youthful.
Canthal Tilt
Eye angle
The slope of the eye from the inner corner to the outer corner. A small positive tilt lifts the eye and reads alert; a negative tilt can read tired.
Nasofrontal Angle
Forehead to nose
The transition where the forehead meets the bridge of the nose, viewed from the side. It sets how deep or shallow the brow-to-nose curve looks.
Mentolabial Angle
Lip to chin
The fold between the lower lip and the chin. It controls whether the chin looks balanced, recessed, or over-projected.
Golden Ratio
Length to width
Face length divided by face width. Faces close to Phi (about 1.618) tend to read as balanced.
How to Take a Good Photo for Measurement
The math is only as good as the photo you feed it. These six tips keep your numbers honest and repeatable.
Stand back, then zoom in
Shoot from at least five feet away and zoom, instead of a close selfie. Close lenses stretch the nose and flatten the jaw, which throws every angle off.
Use a true side profile for jaw and nose angles
Gonial, nasofrontal, nasolabial, and mentolabial angles are read from the side. Turn a full 90 degrees and keep your head level, eyes forward.
Use a straight front shot for eyes and ratios
Canthal tilt and the golden ratio need a face-on photo. Keep the camera at eye height so your features are not tilted up or down.
Relax your face
No smiling, no clenching. A tense jaw or a grin changes the lip and chin angles and gives you a reading that won't repeat next time.
Flat, even light
Hard shadows hide the exact landmark points. Face a window or use soft, even light so the inner eye corner, jaw corner, and chin tip are easy to mark.
Keep conditions the same to compare later
If you want to track changes over time, repeat the same distance, angle, and lighting. Consistent photos make your saved results comparable.
What Helps and What Hurts Your Accuracy
A few small habits make the difference between a number you can trust and one that changes every time you measure.
Marking the deepest point of a fold, not the surface
Nasion and the mentolabial sulcus are the deepest dips. Mark those, not the skin around them.
Zooming the photo before placing points
Bigger landmarks mean smaller click errors. A few pixels off can shift an angle by two or three degrees.
Taking the same shot twice and averaging
Two careful reads that agree give you confidence the number is real, not a fluke of one click.
Using a close-up selfie
Lens distortion near the face inflates the nose and warps the jaw line. Your angles will be wrong.
Tilting the head up or down
A tilted head changes the apparent jaw and nose angles. Keep the chin level and eyes forward.
Reading one number as a verdict
A single degree outside a range means little. Look at the full picture across all measurements.

A Note on What These Numbers Mean
Mathematically average faces can look flat or synthetic, while a distinct nose or an uneven smile often adds the character people remember. These angles give you a blueprint of balance, nothing more. They do not measure expression, health, or worth. If you are weighing a cosmetic or orthodontic change, talk to a qualified professional who can assess your face in person. This tool is built for general interest, not medical advice.
