…or make that “phi,” which I’ll go into in a moment. First, let’s discuss facial proportions.
Facial proportions
A lot has been written on facial proportions. In the probably 10 books I own on portraits + all the ones I’ve browsed through in the bookstore and/or library – PLUS all of the guides I’ve seen on the Internet, NOBODY MATCHES PERFECTLY. That is, no two facial proportion references match up to each other.
- Is the hairline at 1/3 up from the brow? Or is it 1/2 up from the brow to the top of the head?
- Is the eyeline at the middle of the head or the browline?
- Is the ear at the mouth line or the nose line?
- Do I believe John Howard Sanden
or Burne Hogarth
? Or neither?
- etc., etc., etc.
Who’s right? None of the artists I’ve seen are right – and I can say this because almost all of them reference their own drawings when they point out proportions, not pictures of real faces. Duh! They all mean well buy they’re just giving you their personal rules of thumb. Let’s go beyond opinion and do some research on beauty – including some good resources for artists, plastic surgery information! After all, how do plastic surgeons know just how long to make a nose or just how much to tweak to make a face pretty again? They certainly don’t reference their favorite book on portraiture by Douglas Graves.
Phi
Okay, back to “phi” or the cryptic 13/8 reference in the title. Phi is a Greek name for what’s also known as “the golden mean” or the perfect ratio or even “Fibonacci.” If you’re into graphic design, you’ve GOT to check this out! It’s a sequence of numbers that, one added to the next makes the third. For example, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, … to infinity. If you divide the numbers, they get closer and closer to the golden mean, or 1.618:1. Keep that in mind: nearly 1/3 but not quite.
As an aside, my brother-in-law has a Mopar book and it concludes with the Chrysler 300M designers. When asked about the bold design, they noted that the car has Fibonacci written all over it. Indeed. In case you didn’t get it, I think the car is stunning and very masculine, a standout in the crowd by any measure (like it or not).
Portraits and the golden mean
Okay, so what do portraits have to do with some dead Italian guy and Chrysler 300Ms? The human face is literally sculpted out of the golden mean. Not thirds, not quarters, not halves… 1.618:1. Check out this reference image from PhiMatrix.com:

If you take the tip of her nose to the back of her head and find the 1.618:1 mark, it’s right at her ear (the “ear hole,” if you will). Starting from that line, draw another 1.618:1 mark and it’s where her neck meets her chin. Draw another one and it’s the back of her eye. Again, and it’s the front of her eye and the back of her mouth. AGAIN and you’re at the bridge of her nose. Finally, one more time and you’re at the front of her teeth and the septum under her nose.
Can you say, “wow?” I knew you could. <pulls on sweater and changes shoes, goes to see King Friday>
And I didn’t even go over the horizontal lines! This picture could even be split into even more 1.618:1 sections ad infinitum and you could keep finding perfectly matched features (of course, the more attractive the person, the closer to perfect, which is why learning to see is so important!).
Let’s look again:

Holy cannoli, Batman, do you think we’re on to something? If I see one more reference that says that the iris is 1/3 the width of the eye or that the pupil is 1/3 the width of the pupil, I’m going to scream. I mean it, I’ll do it… I will! Watch me! AAAAARRRRGGGHHH!!!
Observations
Okay, I’m better now. But I think you get my point – and I think I have 2 key points that I would like you to take away from this article:
- The proportions of the human face are 1.618:1 all over the place
- You have to use that as a reference and really measure for yourself unless your only subjects are supermodels (keep dreaming)
Keep learning to see and keep on questioning authority. Even me. I’m wrong at least 38.2% of the time (yes, that’s that’s the other portion of the 1:1.618 ratio, or slightly more than 1/3, which is NOT a good number for facial proportions).
