I think it depends on the girl's height, if she is 5ft 4-6 then 5ft9-6ft+ may be suitable. If the girl is 5ft 8-11 then probably will hope for taller guys around 6ft 3+
I'm 183cm, so that's something like 6ft in your messed up imperial system. Get on with the times and stop tying to be special with your feet and inches, England and you other overseas special snowflakes. *rolls eyes*
