How tall is Olaf the snowman in Frozen, really? After the release of Frozen 2, fans were surprised to see Olaf's height listed as 5'4" on the Frozen Wiki – which would make Elsa tower over him at over eleven feet tall. Voiced by Josh Gad in both movies, the talking snowman is Anna and Elsa's comedic sidekick and the star of the Frozen shorts Olaf's Frozen Adventure and Once Upon A Snowman. Olaf quickly became a fan-favorite due to his irreverent, existential comedy and his stand-out songs "In Summer" and "When I'm Older."
