(My qualifications: visual female with an artistic eye, some experience but also a fan of amateur, er, "productions," so I've seen my fair share. I've only ever misjudged a man's size before seeing the goods [or asking] maybe once in my life.)


Robustness: The number one indicator for size I've noticed would have to be this. Not necessarily height (I've actually noticed virtually no correlation there), nor hand nor foot size (some correlation, I'll get to that later), but robustness of the facial structure itself and of the man's physical features. This varies within each ethnicity, but if a man has more robust features for his ethnic group, I've noticed he tends to be larger than the average for that group as well. If you have a good idea of what the average "look" is for all the ethnic groups in a guy's background, you can probably figure out from the composite (him) which sides he takes most after, and how he measures up against the average.

Things that indicate more robust features (and a better chance of being average-to-big):


- A larger, broader nose (this actually seems like a very strong indicator so long as it's not the only robust feature [and sometimes even when it is], especially in conjunction with the following trait-)
- High, broad forehead and widely spaced eyes
- Broad, square face
- More robust bone structure (a guy who looks solid, as opposed to having a delicate frame/facial structure. Even a small guy can be quite robust for his size.)
- Triangle shaped figure (excluding fat; broad shoulders that taper to the waist)
- Tendency towards being muscular, even (especially) without exercise
- Tendency to gain firm fat, as opposed to loose, jiggly fat
- Naturally being a touch darker than another from the same race/s
- Hands/feet : depending on the guy, either meaty and/or knobby hands (size and length not necessarily an indicator, it's more of a proportional thing); with feet I haven't noticed much of a correlation.
- Muscular legs (I know this sounds random but I've noticed that guys with "nice" legs, perhaps a bit larger in proportion to their torsos than most men, tend to be bigger)

Particular combinations of non-robust features that seem to correlate with being smaller:

- Fine bone structure, especially in conjunction with narrow shoulders.
- Small altogether, in a non-robust way, ei, being both short and delicate/fine-featured.
- Skinny legs. Like teen hipster skinny.
- A rather small, even feminine nose. I think of it as the "Irish nose." (Short, slim, button-like). Especially in a face that isn't particularly robust in any other way.
- A touch paler than the average for their ethnic background, especially in conjunction with fine features.

Another random correlation I've noticed that has nothing to do with robustness concerns a man's eyes. It's hard to describe, but it seems like the more hooded/fatty the lids are, the more likely the guy is to be bigger. Ei. Bags under the eyes when he smiles that have nothing to do with age or being tired, fatty upper lids (a bit like an Asian guy's eyes, but of the European/Latino variety.) Robert Downey Jr. (http://i.imgur.com/B20ua.jpg) and Leonardo DiCaprio (http://i.imgur.com/rfzpn.jpg) are great examples of this.


As for personality tip-offs, everything Anon listed is pretty true, but I've found that quiet confidence is the best indicator of all of a well-endowed man. The key word here is quiet; no alpha-male, look-at-me, I'm-so-awesome-and-studly bull****. A man with a big dick, no matter how self-doubting in other areas, knows on some level his dick is big and the confidence from that will bleed through when the topic of sex and male virility is on the table. He doesn't need to act flashy and big to make himself feel like a man, the biggest proof of manhood is in his pants, and most guys who are blessed down there actually tend towards quiet and/or modest. They also may have a sort of smiling, I-have-a-secret, smirkingly passive way of watching guys who do feel the need to act big and flashy.
