Free tools
All free, no sign-up, instant. Every number a calculator produces comes with a "so what" attached — a visual reference, percentile data, or a first-impression read.
Height comparison
Two heights side by side at true scale: the gap in cm and inches, and where the eye lines land. Embeddable on your own site.
Body fat calculator (Navy method)
Estimate body fat from height, neck, and waist — then jump straight to the visual reference for your exact percent.
Canthal tilt test
Measure the height gap between your inner and outer eye corners — positive, neutral, or negative. Runs in your browser; the photo never leaves your device.
Facial thirds test
Upper, middle, and lower third as percentages — plus an honest answer on whether equal thirds actually matter. Same in-browser, nothing uploaded.
Midface ratio calculator
Pupil-to-upper-lip divided by facial width, with the ideal range and a straight answer on how much the number is worth.
Face shape detector
Tap eight points and get the four ratios that decide your shape — oval, round, square, rectangle, heart, diamond or triangle. Every ratio shown, no black box.
Face symmetry test
Left-versus-right deviation at the eyes, mouth and jaw against your own midline. Comes with the reason to distrust the photo before you distrust your face.
Golden ratio face calculator
Three classic φ ratios and how far each sits from 1.618 — plus an honest answer on whether φ can judge a face at all.
Reference data
Which one do you need?
Pick by the question in your head, not by the tool's name. Question on the left, where the answer lives on the right.

Frequently asked questions
Are these tools actually free?
Yes — free, no sign-up, no trial. No email, no card, and no "pay to see your result" step: every tool shows its full output on the page.
Do my photos get uploaded?
No. The facial-proportion tools (canthal tilt, thirds, midface ratio, face shape, symmetry, golden ratio) run entirely in your browser — the photo never leaves your device and never reaches our servers. The height and body-fat calculators only handle the numbers you type; no photo is involved.
How is a tool's number different from the test's read?
A tool measures one objective input — a ratio, a percentage. The first-impression test reads what those inputs add up to in a real person's eyes in about 1.2 seconds. The two can disagree without either being wrong: unremarkable individual numbers can combine into a strong read, and the reverse happens too.
If a ratio comes out "off," does that mean I'm unattractive?
No. Ratios describe structure; they don't deliver a verdict. What carries the most weight in a real first impression is the changeable layer — body fat, hair, fit of clothes, skin, posture — and that layer is exactly the part you control. Bone-structure ratios matter far less than the internet claims.
Tools measure one input — the test reads the combination
1 minute. The AI combines face × physique × outfit × vibe and writes what the 1.2-second first impression actually registers — plus your ceiling.
