Does the Golden Ratio hold the Ideal Penis Size?

For you number nerds, divide a selected Fibonacci number below by the third one to it’s right, and you get the 0.236 (or the inverted derivative 1-0.236=0.764) ratio.
{1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, .. } Examples: 13/55, 21/89. 34/144, etc.

Now multiply your favored length by 0.764 to get the girth, or divide your favored girth by 0.764 to get the length. Go to and try it out by comparing “your” penis size of 5” girth x 6.5” length (5/6.54 = 0.764) to any of their average stats. It’s a pretty tough ratio to beat, IMHO.

BTW, I just realized that my computation gives a close equivalent of Krowax’s square root of 1.618 (1.272). Note that 1/0.764 = 1.31, rendering the same multiplier (instead of my divisor). UpTo7’s stab at 1.3 is also in the same ballpark. Interesting stuff.

I’m relatively new to this, but this golden ratio thing is something I’ve been thinking about for a couple weeks now. I saw this post last night & decided to join in not only on this conversation but on this whole exercise overall. I’m very interested to see what happens.

So, the golden ratio. After giving it some thought I think I figured out the right one. Here is the equation.
Erect Length (EL)
(EL/2) x .618 = S
EL - S = ‘Golden Girth’ (circumference)

So here are some examples:

Length / Girth or Circumference (gain in girth per inch in length)

4 / 2.764
5 / 3.455 (+ .691)
6 / 4.146
7 / 4.837
8 / 5.528
9 / 6.219
10 / 6.910
11 / 7.601
12 / 8.292

What do you guys think? Notice that the magic number in girth is .691 inches per inch in length. I, personally think that there is something to this ratio. It’s just much to common throughout nature not to.

I have to agree with previous posters that placed the ratio closer to 1.2, BPEL/EG.

My 7.25/5.625 = 1.28

An 8 by 6 is considered by many to be the almost perfect penis size; it fills a vagina extremely well, yet is not too large to be unpleasurable during anal. It is an the edge for deep throat oral, but is doable.

Kdong Starting: 7.1 x 5.125 vol = 14.84 cu. in. Current: 7.1BPEL 5.5 MSEG = 17cu. in. GOAL --> 8.5 x 6.5 vol: 28.6 cu. in.

Took Time off, lost some gains-- Girth cemented

No PE since 2015 -- starting back up

This golden ratio is way off, way off.

[BPEL Length 8.5] [NBPEL 8.0 - 8.5 Depending on EQ!] [BEG- 7.2] [MIDSHAFT 6.4/5] [GLANS- 6.1]

PE for life!

In this case I believe that the golden ratio would correspond to diameter of girth, not circumference and so 1.3 is near enough the mark.

I do think there is something to it.

Life is great, enjoy it

Starting/Current Stats (BPEL*MSEG*BPFL) - December 2011: 6.4*5*4.2

Final Target: 9.6*7.6*7.2

If My goal is 10” BPEL then it would need to be 6.25 in girth.

I think girth needs to be bigger. Just my thoughts.

You guys are crazy.

Size is little more than a controllable perception without an accurate means of measurement.

I like 8x6 as the right size

My goal is 8x6 or 1.333 ratio; I beleive that total volumn is what the gal’s like. I’m 7.75x5.91 (21.5 so my goal is within sight.

CWCLARK; Begin_11.11.2010: BPEL=6.5; BEG=5.2

Current: BPEL=7.87(20.00cm); BEG= 6.06(15.39cm): MSEG=5.75(14.61cm). Volume=20.9 (53% increase)

GOAL: BPEL=8.0; BEG= 6.5: MSEG=6.0

I’m 6.5” BPEL, and 5.1” girth! Gains bitches! Now I fill a roll of toilet paper. Ha! Honestly is 3” girth normal? Or is that something you made up?

5.3" NBPEL.

BPEL 6.5-6.7" Goal: Anything!

Girth: 5" but getting bigger. ;)
