Kenyan Sand Boa Size question

[Stewart_Reptiles]

I have a Kneyan Sand Boa whom Deb was kind enough to help out by sexing visually a few months ago. Now I'm curious, particularly for anyone who isn't able to reliably sex visually, is there a size at which it becomes clear that you have a female vs a male?

Once they are adult there is a major size difference but of course when they reach adult size will vary from one to another depending on how the animal is being fed.

If the animal is over 20 inches and 200 grams it's most likely a female, males usually max out at about 18 inches and 200 grams.
