The Human Hand and Foot


Your hand shows Phi and the Fibonacci Series

There are many examples of the Divine Proportion found throughout the design of the universe and everything in it, but let’s take a look at one of the most important things first: You!   We’ll need a few Golden Section / Fibonacci building blocks:

Successive Golden Sections of a Line based on phi, the golden ratio

Each line is 1.61804… times longer than the one before it. (Conversely, a section drawn at 0.61804 (or 61.8%) of each line equals the length of the one before it.)

Let’s start with something simple. Take your hand off your keyboard or mouse and look at the proportions of your index finger.

Your finger demonstrates the Fibonacci series of 2, 3, 5, 8

Hold your hand up to the screen. Don’t be shy!

Each section of your index finger, from the tip to the base of the wrist, is larger than the preceding one by about the Fibonacci ratio of 1.618, also fitting the Fibonacci numbers 2, 3, 5 and 8.

By this scale, your fingernail is 1 unit in length.

Curiously enough, you also have 2 hands, each with 5 digits, and your 8 fingers are each comprised of 3 sections.  All Fibonacci numbers!

The ratio of the forearm to hand is Phi

Your hand creates a golden section in relation to your arm, as the ratio of your forearm to your hand is also 1.618, the Divine Proportion.

Even your feet show phi

The foot has several proportions based on phi lines, including:

  1. The middle of the arch of the foot
  2. The widest part of the foot
  3. The base of the toe line and big toe
  4. The top of the toe line and base of the “index” toe

Note that not every individual has body dimensions in exact phi proportion but averages across populations tend towards phi and phi proportions are perceived as being the most natural or beautiful.

“and your 8 fingers are each comprised of 3 sections”…

You are wrong, we have 10 fingers. The thumbs also have 3 sections each.

Thumb is not technically a finger

you are wrong. the thumb doesnt count as a finger.

Those people with ten fingers had a curse on them, many of them over the years became pirates. I am not talking about thumbs. It was like God cleared the earth during the great flood of all of those tainted children born of women having sex with the gods of old, as the bible refers to them. In other words, they were aliens. Just like the kind of people you find hanging out in sleezy bars….LOL.

Not wrong. Just a different viewpoint. shows the first definition of “finger” as “any of the terminal members of the hand, especially one other than the thumb.” Thumbs have three sections beyond the wrist while the other four digits/fingers have four, so the “terminal” section of the thumb has two sections.

Maybe I am missing something. Phi is a ratio of two things: hand/forearm, finger digits. Which lines from the foot illustration does one compare?




Gary Meisner March 14, 2013 at 9:20 pm

Each of the lines represents a golden ratio of the one that precedes it, which is often how Phi is expressed in life. The first four phi lines fall at the arch, ball and base of the toes.

Thumbs do count as fingers and the thumbs only have 2 phalanges each.
