I have to admit that I laughed way too hard when I saw this question on the Hubpages questions page.

But I will try to answer it as objectively as possible.

Personally I don't think that dildo size has much to do with height, unless you are very short, for instance, Thumbelina, pictured below. We all know her story, correct?

When it comes to selecting a dildo, most people think about width more than length. You don't want a gigantic, holy-crap-it's-as-big-as-a-child's-arm dildo if you have trouble putting in a tampon because of tightness issues. A slender one is usually better.

So if you have a midget who has had a lot of sex or otherwise has a wider vagina, she will probably use a normal sized dildo. At the same time, a woman of average height who is rather tight, will probably use a small one to prevent pain, blood, and awkwardness.

As far as depth goes, that's based on personal preference anyway.

Now when it comes to anal dildoes, that is an entirely different matter. Most anal dildoes are small to begin with and therefore, there is no problem.
