How tall can a hobbit get to?

Answer 1

Hobbits don't actually exist, so the only thing we have to go on is what Tolkien said: The oldest recorded age for a hobbit prior to Bilbo Baggins was the Old Took, who lived to be 130 years old. Bilbo celebrated his 131st birthday before leaving for the Grey Havens. (Since Bilbo and Frodo (and eventually Sam) went to the Undying Lands, technically there's no upper limit, though Bilbo lived the longest of any hobbit in Middle-Earth.)

Answer 2

The tallest hobbits recorded (Merry and Pippin) were 4 foot 7 and four foot eight. BUt the tallest a 'naturally tall' hobbit was was four foot 5 (Brandobas 'Bullroarer' Took)

Answer 3

Hobbits come of age at 33.
