Height is not a high factor for dating for me... I value personality and values over physical attributes!

Well obviously on apps like Tinder, Bumble etc which are the most popular, you don't mention your height so that shouldn't affect the amount of matches you get. It might affect things later if you meet up, but not initially.
I've met up with plenty of girls from Tinder without having once mentioned my height. Some said they could judge my height from my photos, but I don't know.
Just make sure your pictures are good quality and have a preference for girls who are similar height to you or preferably shorter, they'll be far more open to you. Most girls who are concerned about height are really only after a guy who's taller than they are.
