breeding kings?

I've been reading about King breeding and have not found anything that actually says what size the female should be.
Can anyone help me out?

Well I don't know an exact weight (would depend on species) but the female should be 3 years old at least and in good health/weight for her size.

My female that I'm breeding this year is a 4' long california kingsnake.

thanks for the info

my new female is 2 years old and I'd say a little over 3 feet

but she looks pretty small to me compared to my 4 year old male

I think she'll be ready next year
