Chameleon age?

[pascal2023]

So I got this lovely girl 5 days ago, I was told she is 4 nearly 5 months old. However when I collected her the ‘cage’ she was in had quite a few other baby chameleons who were also apparently 4/5 months old but I thought it was a little odd considering the others were different sizes ( roughly same size as her or smaller/ tiny and I mean tiny ) … would anyone be able to give me an insight to how old she could be? With her tail out stretched she’s about 8 inches long (head to top of tail, I’m assuming that’s how they’re mesasured) … but looking at this conversion chart that would make her 3 months old right ?

Is there actually any way I could get her age checked ?

Thanks in advance and sorry for the bad photo

This might help...but it's always hard to say for sure since it depends on their genes and their care...
