Now (this is just theory not facts someone with more knowledge should work this out) what you do is divide that size by 4 and and then you have sling, juvie, sub adult and adult. What do you guy's/girls think?

Not going to shoot it down.
I get what you are saying, but really to go into such specifics like that.

lets take a darf species that only gets to 6cm, so we say 6cm divide that by 4 giving you 1.5cm

So
0.5cm up to 1.5cm sling
1.5cm to 3cm juvie
3cm to 4.5cm sub adult
4.5cm to 6cm mature adult.

So lets take a spider that get to 25cm

25cm divide that by 4 gives you 6.25cm

0.5cm to 6.25cm sling
6.25cm to 12.5cm juvie
12.5cm to 18.75cm sub adult
18.75cm to 25cm Mature adult

0.5 to 4cm sling
4 to 7 juvie
7 to 10 sub adult
10 and up adult and once it matured and is ready to be mated it is Mature adult

.

@cascade, thanks that sounds exactly how i thought it should.
I knew it cant be age related because 2 slings from the same sack will almost never grow equally even if they are kept identically with regards to temp, humidity and feeding schedule.

Yes what you are saying is very true. But then if you go to your method once again you have some complications. Like for instance a dwarf T, a 6cm adult would then be a juvie and remain so for the rest of its life.

I think we can safely say there is no sure way to class them we can just guess. It all depends on what specie and each ones size as an adult. But for an average sized T your method should work. I just tried to do it with T's as a whole that's why I said " (this is just theory not facts someone with more knowledge should work this out)".

Why do you say a dwarf spider will be a Juvenal for the rest of its life?

Look at it this way.
You get a sling, it looks like a tarantula but it does not look like it mother or father.
Then you get a Juvenal, starts getting it mother colors bulks up and becomes a little tarantula.
Sub adult, a couple of molts away from becoming Mature
Mature Adult, Male or female, that is ready to breed.

Jup that makes sense. I was just referring to your sizes each T will have to have their own size indicator list as you have given because some don't get as big as others, so in some cases a smaller T would be close to adulthood but because it is small it will still be considered a juvie if you go with your
"0.5 to 4cm sling
4 to 7 juvie
7 to 10 sub adult
10 and up adult and once it matured and is ready to be mated it is Mature adult."

Just a example. I'm putting this as a question as I don't have experience with T's so I might be wrong. At what size is a L.parahybana mature? The way I see it is because they can reach about 24cm + it will only mature when they are 16cm+ big (this is what I presume i'm kinda comparing T's to my snakes as this is more my area of expertise) so a L.parahybana smaller that 15cm or 12cm would not yet be adult but more of a sub adult.

But I'm just getting to technical I try and complicate everything because to me it doesn't fit but actually it is right. hehehe sorry don't want to fight just want to learn and just giving my opinion.
