I honestly don't think BCC get as big as some think they do. They may have reportedly been larger in some cases, but my 4 year old Suriname BCC female is only 6.5 feet and I have some 3 year old BCI female's that are all of 7 feet. BCI are much easier to care for though, BCC don't do well with ANY husbandry errors at all.

To answer your question though- An adult BCI female should in most cases be MUCH bigger than a BCC male.
