Emma Frost's age is somewhat ambiguous due to Marvel's sliding timescale and various storylines, but generally, she is portrayed to be in her early 30s in the current Marvel Universe timeline.
- During the "House of X/Powers of X" (HoX/PoX) storyline, she is estimated to be around 30-31 years old, slightly older than the "O5" X-Men team who are roughly the same age as her when she was 17-18 in her solo series
- Earlier comics suggested she was about 28 during Grant Morrison's New X-Men run, placing her in her early 30s now, a few years younger than Scott Summers (Cyclops)
- Some sources specify her birthdate as July 14, 1972, which would make her about 52 years old in real-world terms, but this does not align with the in-universe sliding timeline where characters age much slower or inconsistently
- The sliding timescale means characters like Emma Frost remain perpetually young adults despite decades of publication history
In summary, within the comic book universe's internal chronology, Emma Frost is approximately in her early 30s, though exact age is fluid due to Marvel's timeline conventions.
