How big can yellow belly turtles get on average?

Question

what's the average size of a fully grown yellowbelly turtle?

Answer 1

if you mean yellow belly slider.

males- 8 inches

females- 12 inches

you cannot tell the s*x of the turtle until it is over 4 inches long. males have very long claws and a fat tail. females claws are short and so are the tails.
