Palm compatibility: compare two hands, line by line

Scan two hands on one device, one after the other, and see your lines laid over each other. Palm compatibility here is read as tradition and something to talk about. There is no score.

Put your palm next to someone else's, and you see at once how different two hands can be. An article can only describe that, so this tool lets you do it: your two real palm traces, on one drawing, with the differences measured. It works when you are both there, on one phone or computer. It doesn't say if you're right for each other, because nothing on a palm can.

How to do it together

This works best sitting on the same side of a table, with a lamp or a window nearby.

  1. Both of you, with one phone or computer, somewhere with even light.
  2. Press the button. Whoever goes first holds up one open hand, or chooses a clear photo of it. Either hand is fine.
  3. Drag anything that looks wrong, then press Next hand.
  4. Pass the device over. The other person does the same, then presses See both hands.
  5. Read the overlay and the line-by-line table together, and use the questions on this page.

Each hand goes through the full scan, so you can correct your own lines before passing the device along. Left or right doesn't matter: each hand is flipped into the same palm space, and each is measured against its own width. A big hand and a small one can be compared fairly because of that.

Two hands, one picture

The result lays both sets of lines on one palm, the same shape for both by construction. So what you see differ is the lines themselves. It also counts where your lines cross, for fun, and each hand gets a name to go with it.

ExampleDrawn to show the idea: these lines aren't anyone's.

What gets compared

Three lines: heart, head and life. For each, the tool puts what it measured on each hand side by side, then says where they differ.

  • Length, in palm widths, each hand against its own palm. A gap under 0.08 of a palm width counts as "about the same length", because the same hand photographed twice can move about that much.
  • Shape: straight, a gentle curve, curved or a deep curve.
  • Where it ends: under which finger, say, or how near the wrist.

Your two hand types get a short paragraph too, with both sets of ratios, written as an old book's picture of the pair. Here is one real row, from two photos we ran through the tool:

Example: the life line row from two sample photos.
First handSecond hand
Length0.92 palm widths0.64 palm widths
ShapeA gentle curveA deep curve
EndsNear the wristIn the middle of the palm
What it says"The first hand runs longer, by 0.28 palm widths. Different shapes. They end in different places."

Some things are left out on purpose. If a line comes up faint on either photo, the tool writes "Nothing to compare here until both lines read clearly", because a faint trace isn't a measurement. The fate line isn't compared, since a photo can't read it reliably. The marriage lines aren't compared either: the scan doesn't search for them. And nothing adds up to a score, a percentage or a ranking. The scanner page explains how each trace is made.

Questions to ask each other

This is the useful part. Find the rows where you differ, and try the question that goes with each. They're written as questions because that is all a line can give you.

  • Your heart lines differ in length

    Who says it out loud when something's wrong, and who shows it another way?

    One popular reading is that very different lengths mean giving unevenly. Your table says only which line is longer.

  • One heart line curves and one runs straighter

    When you picture a good year together, what does each of you see?

    Modern pages read an upward curve as the idealist's line, and a straighter one as balancing feeling with reason.

  • Your heart lines end in different places

    What does being looked after mean to you? Would the other person have guessed?

    Cheiro read an ending under the index finger as "firm and reliable" and between index and middle as "a calmer but a very deep nature".

  • Your head lines end in different places

    When there's a big decision, who needs to talk it through, and who goes quiet first?

    Palmists take the head line for how a person weighs things. Cheiro called it "like the needle in the compass".

  • One life line swings further out

    How much of a free weekend do you each want to spend with other people?

    Readers take the life line's reach as how far you range. It has nothing to say about how long you live.

  • Your lines look nearly the same

    You look alike on paper, so where do you know you're different?

    A match can feel like a sign. That's a good reason to look for the part it misses.

What the tradition says about two hands

Not as much as you might think. The older books we read describe one hand at a time. Cheiro has plenty on what a heart line shows about a person, including that it "relates purely to the affectionate disposition", and on the short lines at the palm's edge, of which he says "only the clearly formed lines relate to marriage". Comparing two hands line by line looks like a modern habit, as far as we can find. Numerologist.com, for example, reads partners with very different heart line lengths as giving unevenly, calls this "not a moral judgment", and offers no studies.

If you want to read further, the heart line covers what each start and shape is said to mean, the love line puts the three signs read for love on one hand, and the marriage line looks at the palm's edge, which you can only compare by eye.

Why a match can feel so right

You'll probably find something in your result that fits you two perfectly. That doesn't mean the palm knew. In 1949 the psychologist Bertram Forer gave 39 students the same description, assembled from a newsstand astrology book, and they rated it about 4.3 out of 5 for accuracy. People find personal-sounding statements true, more so when they're warm and flattering. A reading about two people has twice the chance of landing.

Biologically, as one 2019 study puts it, the line of life "is merely another flexion crease", and the others are creases too. They formed before either of you met anyone. Enjoy this for what it is: an old game, a good excuse to hold hands, and a way into a conversation you might not otherwise have had.

When not to use it

Not as a verdict. Don't use it to decide whether to stay with someone, marry them or leave them, and please don't use it to win an argument. It can't see any of that.

Not on someone who isn't there. It is meant for two people who are both up for it, at one device. Don't run a partner's photo through it behind their back. If a relationship is causing you real worry, talk to someone you trust, and not to a website.

Questions people ask

Can you tell compatibility from palms?
No. No good evidence shows that palm lines predict anything, and that includes how a relationship will go. What you can do is compare two hands and use the differences as a way into a conversation.
Which lines do palm readers compare?
Mostly the heart line, for how feeling gets shown. Then the head line, for how each person thinks things through, and sometimes the life line and the marriage lines on the palm's edge. The tool compares heart, head and life, the three the scan can measure.
What does it mean if our heart lines match?
Only that they're about the same length or shape on this photo. Palmistry would say you show feeling in a similar way. That may ring true, but people find similarities meaningful whatever they are. It's a better question than an answer: is that how it feels to you both?
What does it mean if our heart lines are very different?
Not that you're a bad match. One popular guide reads very different lengths as partners giving unevenly, and calls that "not a moral judgment". It offers no studies. Take it as a prompt: who says it out loud, and who shows it some other way?
Do both people need to scan?
Yes. The tool is built for two people at one device, one after the other, each holding up their own hand or choosing their own photo. Please don't run someone else's hand through it without them there and happy to do it.
Is there a compatibility score?
No, on purpose. Nothing adds up to a number or a percentage. The tool shows two sets of lines and says where they differ. Any score from two sets of skin creases would be invented.
Is this a verdict on our relationship?
Never. It can't tell you to stay, go, marry or wait. If something in your relationship is worrying you, talk to each other, or to someone you trust. A crease can't help with that.
What should we do with the result?
Read it together, laugh at whatever's wrong, and pick one of the questions on this page to ask each other. You can save the overlay as a picture too. Your photos aren't in it.

Two hands, one device, no verdict

See what your lines do when they share a palm, then see what you make of it.
