This obviously isn't an exact figure, but from my experience it seems that:
90% of women probably don't care about your height unless you are just VERY short (like that guy from Jackass). Just like they won't care about a 4-inch penis, a weird lisp, a balding head, or any other physical "issue" someone "thinks" they have. Let's be honest, would you instantly shut down a girl if she has small boobs? Maybe 10% of guys, but most would not.
And 99% of these women WILL NOT care about any of this this stuff once you get them in a comfort or attraction zone.
If your issue is getting past an initial impression with the woman, you can start by just compensating with something else (nice clothes/accessories, humor, etc.) But in all reality, long-term, you will find that your own self-worth, and your ability to just feel good in your own skin, will make your physical traits completely irrelevant. In other words, you can be an ugly, short, gimp that doesn't speak english and still attract women if you just make them feel good about being around you.
