Palm Line Measurement & 손금 Reading
You trace 생명선, 감정선 and 두뇌선 over your own palm photo with a few drags. Length relative to the palm, curvature, forks and breaks are then measured exactly from the polyline, each with its traditional reading.
You trace 생명선, 감정선 and 두뇌선 over your own palm photo — four control points a line. The page then measures each line’s length against the palm’s own length, how straight or bowed it is, how far round it turns, where it ends across the palm, and where along it a break or fork falls if you mark one. The readings are Western chiromancy, quoted with its sources.
For fun. The lengths and curves below are exact measurements of the lines you traced. The readings beside them are Western chiromancy, quoted, and they predict nothing.
Your photo
Drop a photo of your open palm, or click to choose one
Palm flat and filling the frame works best. The file stays in this tab.
The photo stays in this tab. It is not uploaded, not stored, and not written to your browser’s storage; it becomes a temporary in-memory URL for the picture element and is released when you leave the page or choose another photo.
The other tool built the same way is 관상 — you place the landmarks, and the ratios are measured exactly.
How to use it
Set the palm’s own length and width first
Wrist crease to the base of the middle finger, and the two side edges. Every measurement below is a ratio against those, which is what makes the numbers comparable between a close-up and an arm’s-length photo.
Trace each line with four drags
Four control points is enough to carry the bow of a line, which is the part the tradition reads. The traces are coloured so you can tell which one you are moving.
Mark a break or a fork if there is one
A polyline cannot tell where a line is interrupted — that is your observation, not a measurement. So you place the mark and the page measures the one thing it can: how far along the line it falls, which is exactly what the manuals read.
Common questions
Why not detect the lines automatically?
Because it would get them wrong quietly. A ridge filter works on a palm pressed flat under even light and fails on a phone photo: the hand is curved, so the strongest dark ridges are the shadows in the cup of it, the finger creases are stronger than the heart line, and skin texture answers everywhere. It would not report failure — it would report a line, confidently, in the wrong place, and the reading built on it would look exactly as authoritative as a correct one.
Does a long life line mean a long life?
No, and the tradition the claim is made in the name of does not say so either — Cheiro is explicit that the life line’s length is not read as a length of life. Palmar creases are flexion creases: they form in the womb by about the twelfth week where the hand folds, and nothing about them is known to bear on how a life goes.
Is 손금 a Korean tradition?
The three-line scheme is not. 생명선, 두뇌선 and 감정선 are the life, head and heart lines of Western chiromancy, systematised in nineteenth-century France and England and translated in. East Asia has its own hand-reading tradition and 『마의상법』 carries a 手相 section, but that is a different scheme from the one on this page — and saying so costs nothing.
Does the photo get uploaded?
No. It becomes a temporary in-memory URL for the picture element and is released when you leave the page or choose another photo. Nothing is uploaded and nothing is stored.

Daily Fortune by Zodiac Animal & Star Sign
Composes one day’s reading for a zodiac animal or star sign from the day’s own 일진 and the traditional temperament of the sign. Seeded from the date, so it is the same all day and refreshing does not reroll it.

Four-Axis Personality Questionnaire
Our own forced-choice questionnaire on the four public dichotomies — 24 items or an 8-item short form — scored as a strength bar per axis rather than a hard four-letter verdict.
Zodiac Compatibility (궁합)
Two birth dates give two animal signs and two day stems. Reports the exact relation between them — 삼합, 육합, 충, 원진, 형, 파, 해 — and the five-element relation of the day stems, each with the traditional verdict.
