I'm sure we all know how old most of the Disney Princesses are since we get to know it from their movies, but some of them has a different age in their original and some aren't even mentioned, but this is mainly what other have said, but it's also my guessings on some of them. Anyways enjoy!

Snow White:
There has been many discussions on how old she is in the Disney movie since it's never mentioned, but if you didn't knew it already she's 14 in the Disney version. In the original fairytale she's only 7 years old as most of us know, but did you knew that in most of the newer versions of the classic fairytale she's more older, in one version I found she was 18, in another version she was 7 at the start of the story, but 17 when the prince finds her so out of all the princesses I think that she has not only a really big age diffrence between the original fairytale and the Disney version, but she has had the biggest variation of age out of all the princesses.

Cinderella:
Another princess that there's been lots of discussions regarding how old she is in the Disney version, but I think that she's 18 in that version. In the original version she has to be a bit younger like 15-16 maybe less, but this is what I think. In the newer versions of the fairytale she's between 16-18 I think.

Aurora:
In the Disney version she's obviously 16, we all know that, but in the original fairytale she was actually 15 when she pricked her finger on the spindle wheel so not so much younger. In newer versions I think she's 17-18, new versions have a tendency of making classic fairytale characters a little bit older.

Ariel:
Another princess who is 16, but in the original fairytale she was 15 when she first got to swim up to the surface. In newer versions she's either 15 or 16.

Belle:
I think that she's 18 in the Disney version, but I also think that she can be either 16 or 17, it's not impossible. In the original fairytale I think that she's somewhere between 16 and 18, that's my guess. In newer versions I think that she's around 19 or 20, but that's just me guessing.

Jasmine:
Many people says that she's 16 in the Disney version like most of the other princesses and I think so too since I guess that in her time you had to marry a prince when you're 16. That's what I think is the age of her in the original fairytale. In newer versions she's either 17 or 18, again I'm just guessing.

Pocahontas:
She's the oldest of the Disney Princesses at an age of around 21 according to what I've heard. In real life she was only 12 when she first met John Smith. In newer versions she's probably at least 20.

Mulan:
Most people say she's 15 and that seems right if you're basing it on the time her story takes place. I think she's around that age in the original version. In other versions I think that she's like 17 or 18.

Tiana:
She's the 2nd oldest princess since she's 19 in the Disney version according to the film makers. In the original fairytale she's like 15 or 16 when she kisses the frog and I think that most other versions sticks to that age.

Rapunzel:
Okay, we know that she's 18 in the Disney version, but how about the original fairytale? Well, I think that she's 16 in that version and that's the age that I believe most other versions sticks to.
