Secure enough to date /marry a taller woman? or a short guy?

6'4" would have done,
although I did know someone who was 6'1" with heels she was as tall.
a few around 6.

I knew there were tall women, e.g. in uni basketball team but never ran into them. some may have been that height.

so for these 6' ladies, they were dutch, german, one italian and a few americans, oh and one desi chica, cool girl too, but no other desis that were close.
