 Production was complicated by the use of scale doubles and forced perspective on a level never seen before in the film industry.In the Middle-earth storyverse, Hobbits are 3 ft 6 in (107 cm) tall, Dwarves are slightly taller at about 4 ft 6 in (137 cm), and Men and Elves are average human height, about 5 to 6 ft (150 to 180 cm).However, the films used two scale sets instead of three by casting taller than average actors to play Dwarves, then combining Dwarves and Hobbits into one size scale.
