Floridana will average 4-5' but can reach 7-near 8' in length. I have personally owned a few 6' adults and have seen a monster male that was over 7' and as big around as a soup can. The key to getting them big is feeding hatchling what they want to eat....everything. The first two years are key to any snakes growth potential. Nice looking king. You'll enjoy it thoroughly. They are garbage disposals!
