It is always hard to say how old a comic book character is. The timeline does not always match up.
Kitty was a thirteen-and-a-half year old girl when her powers manifested. She appeared in the comic books in 1980 (Uncanny X-Men #129) so she would be 30 in real-time. However, as I said, the timeline does not always match up.
In the X-Men movies, her character was only recently shown/introduced, so she is portrayed as if she is still a teenager, perhaps of high school age.
Another answer:
20/21
Another answer:
In older comics, she was a teenager of about 15 or 16, but in modern day, she is in her early 20's.
Kitty Pryde, AKA Shadowcat, can phase. Essentially, she can pass herself and anyone she is in contact with through solid objects. She is also able to disrupt electrical fields. She uses this to "float" or walk on air.
In the X-men movie trilogy, Shadowcat is played by three separate actresses. In the first X-men film, Shadowcat is played by the actress Sumela Kay. In the second, she is played by Katie Stuart. In the third, she is played by Ellen Page.
The original 5 X-men from the 60's are Iceman, Angel, Beast, Cyclops and Marvel girl aka Jean Grey, in the 70's with the release of giant size X-men came the introduction of Storm, Nightcrawler, Colossus, Rouge (from the brotherhood) long story, Kitty Pride aka Shadowcat, Sunfire, Banshee, Thunderbird R.I.P, Lorna Dane aka Polaris, Havok and of course Wolverine, In later years Gambit and Bishop were added plus there are numerous other mutants in and out of the world that Charles Xavier built.
