What about transwomen?

Judge: Man Is Too Short for Prison
A 5'1" Nebraska man convicted of sexually assaulting a child was sentenced to 10 years probation because the judge thought he was too small to survive in prison. I wonder if the judge would have done the same for a transwoman who still would be sent to a men's prison because she hadn't had complete genital surgery? Her chances for safety in prison would be no better than his. Maybe less.

I also wonder what the exact height limit is.
