I was 5 foot 8 1/2 (174cm) but was measured as part of a medical over the weekend at 5 foot 7 1/2 (172cm) and for some reason that really helped my height dysphoria. Now I know that I was shorter than many trans women anyway, and I know that being trans I have a tendency to over analyse and fixate on all aspects of what might be feminine, but for some reason the inch reduction actually really helped my height dysphoria. I have no idea why but 5 foot 7 1/2 sounds so much better to me than 5 foot 8 1/2.
I used to be more concerned about my height until I met a transwoman at an event once in London who was around 6 ft 6. But she owned it. No-one ever would have thought that she was trans even with her height. It made me realise that we all have a large number of traits which might be deemed more male, or more female, and so long as there are more of one than the other (and the conclusive gender pointers, such a beard, are not present) people will see you as that gender.
