I will contribute to this conversation as a woman who is on the tall side (5'8") married to a man on the short side (5'4").
Before we were dating, I was a bit turned-off by my husband's height. Mostly this was because I felt awkward standing near him. I have also felt the same way around petite females. I feel like a huge GIANT, which makes me very self-conscious about my own height and weight and general size. I am just not a small person (though not grossly overweight.) My husband's height was one of the complaints I had about him, though we were good friends. My mother basically put my perspective in check, and personality won the day. We are happily married now.
I still feel awkward out in public, but I just deal with it. Since then, I have met a lot of other "odd couples" and it helps to realize that couples come in all kinds of sizes and shapes and ages. (Mostly, though, these odd couples are older...) I think media harms this idea because movies and TV shows always show these "perfectly matched" couples.
My husband is quite short, but most of the guys I have either dated (not many) or were interested in were about 5'6". For some reason, the majority of guys I have ever known throughout my life were on the short side. Dating and marrying someone shorter was something I expected because I am on the tall side myself, and I was used to guys being on the short side. 4 inches is a big difference, but I have gotten used to it.
OP, I don't think you need to draw further attention to your height if you have already put it in your profile.
If a woman is surprised by your height, I wouldn't take it personally. First, even if a woman reads your profile and registers that you are short, she might not be able to "picture" how your height seems in real life. Also, if she feels awkward about the height difference, that is NATURAL. She might not be used to being around a guy significantly shorter. It takes getting used to. She also might not know any "odd couples" and may think that other people may judge her if she's with a guy much shorter. She may not be comfortable in her own skin. Expecting her to be completely at ease with herself is a bit much to ask, just as someone expecting you to be completely at ease with yourself in every way is a bit much.
I also have to add that I was a bit concerned about marrying a guy much shorter. Life for short guys doesn't seem to be easy, according to stories my husband has told, and life for tall girls isn't so easy. I was concerned about how the genes were going to mix up when it came to having children. I knew I would help my children accept how they were however they came out, but I am THANKFUL that my son got the tall genes and my daughter got the short ones. If it was the other way around, that would be tough.
So, note that all these things might be swimming around in the mind of a potential girlfriend.
While I would not bring extra attention to your height before hand, if a woman seems uncomfortable about it when you meet in person, go ahead and address it then. You could make a joke about being short or point out some benefits of being short. Something that breaks the ice on the issue and makes light of the situation. It would communicate, "I know that the height difference can feel awkward - it's OK if you feel awkward." Then, when put at ease, she might be able to see your personality come through more.
