While she seems to have drove herself to Mt . Celeste at the start of the game and Core, we never get a confirmed age of Madeline. Also, she jokes that she “drinks and goes through the internet” in her free time.
#What is Madeline’s Age?
round crater
fallow island
I would guess 18-20? since the legal age of drinking in Canada is 18
round crater
That makes sense
balmy lotus
she's old enought to work
she mentions that work is not that bad
and she seems pretty young compared to most adults

we dont know if she lives in canada
she could live in the US and go to canada to climb the mountain like theo
id give my estimate as 24
exotic beacon
we dont know if she lives in canada
P sure she said she lived in Canada at some point
coarse vigil
She’d have to be old enough for hrt regardless, so 18 is the minimum
balmy lotus
whats hrt?
sudden crescent
hormone replacement therapy
the pill bottles on her nightstand in the cutscene at the end of farewell
i'm pretty sure she's canonically at least 20
balmy lotus
hormone replacement therapy
whats that
sudden crescent
estrogen or testosterone
it's for trans people
madeline is canonically transfem, and she takes estrogen
basically gives people some traits of the gender they want to be

More of a fun fact really, but in British Columbia (where Celeste takes place) you dont need to be 18 to have hrt.
Source: I live in the province and have a trans friend who transitioned throughout high school, but I also googled for peace of mind and got results that confirmed that you can be younger than 18 here. Figured I'd put this here to be informative as I've basically witnessed it firsthand
I'm a day late rip
There may be a minimum age still, I'm too tired to read extensively but I can read more into it later to confirm

shes at least 21
since she says in chapter 6 that she drinks
actually nvm the minimal legal age for drinking might be different in canada
not sure
glass furnace
19 in British Columbia
Can be different in other provinces tho
But as shown above shes stated to be in her 20s for sure
