The average adult male wild turkey is between 42 and 45 inches long from beak to tail tip. Domestic breeds of the species differ in size, but the smallest breeds are approximately the same size as turkeys in the wild.
Turkeys are bred for mass, so the most common commercially raised birds, such as the Standard Bronze, outweigh wild males and are correspondingly longer. Smaller breeds, such as the Midget White, are generally not raised on large commercial farms. They are meant for modern small farms. An average length between 40 and 50 inches is fairly standard throughout all commercial breeds, with the most popular varieties skewing longer.
