Depends on the conditions it's kept and feeding. What are you feeding, how often, how big is it now? There really is no "average".

I'm trying to get a guesstimate of how old my little female Luna is, and also my father-in-law just got a baby and he would like to know how old his is.  Luna is about 36" and 642g, and we only got her 8/11, and my FIL's he said is about 17 or 18".

I want to see what other people say ber I give my best guess. But it's hard to judge just on size and weight. I had a male years ago who was a breeding machine and he wasn't much bigger than Luna. And he was 7 yo.

I know it has a lot to do with feeding and what not, but there has to be a general average right? :-/ 

anyone that wants to make a guess, there are pictures of Luna posted.

I'm guessing 2 yo or younger for Luna and she should be eating small rats depending on girth.

For your FIL I would guess 4-10 months. Should be eating adult mice or weaned rats depending on girth.

Balls hatch out at around 10 to 15 inches. Size and growth rate after that are completely dependent on the feeding schedule and temperature.

Wow wtf happened to my font.

I'm with Cenobite - it's so variable you can't even really make a chart.  it also varies by individual, just like people.  IMO, a BP will hit full growth between 2 and 7 years of age, depending on feeding schedule, temp, etc. this is a pretty big window.


my BP is only 32" and he's full-grown.

Your font just Gangstered your ass.

I also agree. I have an almost 2 year old BP, and he's only about 3ft in length, eating small rats.

I also have a 2 1/2 year old BP who is 4 1/2 ft in length , and eating medium rats. 

Only about 6 month or so difference in age, but my older one is MUCH larger.

it depends on the snake, some will grow really long and skinny and some will be short n well FAT... however they should be shedding every 4 to 6 weeks as you feed them, and it depends on how your feeding, how much they are keeping inside, and how much is being wasted, frozen thawed loose alot of nutrients that could make your snake grow faster so feed fresh killed and you should get a better idea of how fast he will grow.

Really depends. I had one that barely grew for the longest time and ate good meals weekly. Whereas my spider female was1500g by a 1 yr 6mo on a once a week feeding schedule (small rats from 400g and up).

As everyone else has said, size really doesn't have a whole lot to do with age. It has more to do with health, genetics and feeding schedule than anything else. I have 2-3 year old males who are 700-800g and 3.5 ft and I have females who just turned 1 yr who are 800-1000g and 3.5-4 ft. I've seen balls kept by "pet people" who did what their pet store told them and only fed 1 adult mouse every 2-4 weeks and their 3 yr old Ball Python is the size of one of my 3 month old babies. Good thing is it isn't really important to know their age, they can live a very long time and if they are smaller than they should be now, the proper feeding schedule will get them to their normal size in no time. Snakes don't really seem to get permanently stunted, growth just slows with less food. It can be corrected easily once they get the nutrition they need! One last thing, different snakes do have different growth rates... I have two females from the same source (not related) who are both 2009 born snakes... fed on the same schedule but the one female started looking fat around 1200g while the other kept growing length wise and reached 1500-1600g. I actually had to stop feeding the smaller female to avoid her getting fat though the amount of food was totally normal for a snake her size... She's just small framed and not meant to be huge! I have another female who is 12 years old and 3500+ grams... Some snakes will never reach that size but others will. Just depends on their genetics and feeding schedule.

Yeah, I know there are a lot of factors.  I was just wondering if maybe there was a way to guess. :-D  But.....thats okay, I asked out of curiosity, it's not like I'm going to love them any less.  I figured it couldn't hurt to inquire.  Thanks guys.
