What is the average length of a ball python when it reaches 1500 grams?

Answer 1

There is data from a study carried out about 10 years ago on just over 200 wild caught balls, the average length of a 1.5 kg ball was about 1.25 meters

Answer 2

I'm not really sure how big 1500 grams is? But usually it depends on the age more than the wieght because some can just be overfed and all fat or underfed and skinny. They usually top out at about five feet and are 1-2 feet for the first year and 2-3 the second, after they second year, they usually hit max size.
