how old are sam and dean?

Their four years apart so Dean is 33 and Sam is 29. But don't get it confused with Jared and Jensen which are a año ahead of their actual characters. Hope this helped as well :)

The series began in 2005. In the pilot, Dean says that he is "26, dude", and Sam has just graduated college at 22. Considering it has been seven years since then, they are currently 33 and 29. I'm currently getting ready to celebrate Sam's upcoming 30th birthday on May 2nd ;P

Dean was born January 24,1979, (As seen on the computer in "The Benders") and Sam was born May 3,1983. Hope that helps.

Dean Winchester is now 37 years old and since Dean is 4 years older than Sam, that makes Sam 33 years old.

As of today Dean is 37 and Sam is 33

Dean is about 32

Dean is 165,375,365,729,628

In Season 1 Dean is 26, Sam is 22
In Season 13 Dean is 38, Sam is 34
