How old do you think the ponies are?

as lauren faust say,
twilight sparkle : 19
pinkie pie and rarity : 20
fluttershy and rainbow dash : 21
applejack : 22

I read somewhere they're about 17-21....

I don't think ponies age the same way as humans. It seems there are children and adults but not much in between. I'd say the mane 6 are young adults. They haven't been adults too long but long enough. Putting an actual number would be hard though.

Well, this is what I think:
Pinkie Pie; 13-14 years old, since she is so friendly & fun and just all-out random. Still like the child who likes to have fun.

Fluttershy; 15, since Fluttershy stated to Pinkie Pie, "I'm a year older than you."

Rarity; Most likely 17. o3o She's into fashion & style, so.

Applejack; 17-19, as she helps the family out with the apple orchard.

Twilight Sparkle; 18-19, because she studies daily and has a very excellent vocabulary. X3

Rainbow Dash; 16-17, just as a guess.

I think they're like teenagers or young adults... they don't go to school so it kind of makes sense.

I don't like to think about it, cuz then I get confused.

maybe in their teens or so...idk let me look it up on google.

Probably the mane 6 ponies are maybe 20-30 years old

Part of me thinks that they're adults mainly because they have jobs and whatnot.

But I really think they are 10-13, it's hard to picture adults going "The power of friendshippp!"

I think there young adults. About 18-20 since they don't go to grade school(anymore).

the main 6 ponys and spike are between 12-18 is what the creator of the the show sead im gesing

spike 12
pinkie 13
fluttershy 14
rainbow dash 15
apple jack 16-17
twilight 16-17
rarity 18

10-13 maybe

I'd think they'd be at least adults by now

In the old one they where like 5 in new one they are like...13-19 I'm estimateing

Umm...
Idk look up on google maybe 18-25

i think pinkie is:13
fluttershy is:15
rainbow dash is:16
rarity is:17
twilight is:19
apple jack is:18

i think spike and the cutie mark crusaders are 10-11
and i think the mane 6 are at least 12, but no more than 14

i think rarity is 19 applejack is 18 pinkie pie 15 twilight 18 rainbow dash 18 and fluttershy 18

I usually judge them by their voices and appearances.

Twilight: 17
Rainbow Dash: 16
Fluttershy: 16
Pinkie Pie: 14
Applejack: 18
Rarity: 19-20

Well ponies have different ages due to humans so i think ...

Pinkie pie . 14
Fluttershy. 15
Rarity . 16
Rainbow dash . 16
Twilight . 18
Apple jack .19

There all teens due to this ....

Fluttershy is a year older then pinkie pie
Most people think rainbow is 21 . It not true
Aj is the oldest
Teens are enbarressing cos they stare round boys
Teewt and party
But its fine !!!

The cmc our between 10 and 12 young 7 th graders.

Celestia and luna stay as 1000 years of sun moon gods

Hope this answers your question .
