A Big Little Book was typically 3⅝″ wide and 4½″ high, with 212 to 432 pages making an approximate thickness of 1½″. The interior book design usually displayed full-page black-and-white illustrations on the right side, facing the pages of text on the left. Stories were often related to radio programs (The Shadow), comic strips (The Gumps), children's books (Uncle Wiggily), novels (John Carter of Mars) and movies (Bambi). Later books of the series had interior color illustrations.
