Draft horses are recognizable by their tall stature and extremely muscular build. In general, they tend to have a more upright shoulder, producing more upright movement and conformation that is well-suited for pulling. They tend to have broad, short backs with powerful hindquarters, again best suited for the purpose of pulling. Additionally, the draft breeds usually have heavy bone, and a good deal of feathering on their lower legs. Many have a straight profile or "Roman nose" (a convex profile). Draft breeds range from approximately 16 to 19 hands high and from 1,400 to 2,000 lb (640 to 910 kg).
Draft horses crossbred on light riding horses adds height and weight to the ensuing offspring, and may increase the power and "scope" of the animal's movement.
The largest horse in recorded history was probably a Shire named Mammoth, who was born in 1848. He stood 21.2 hands (86 inches, 218 cm) high, and his peak weight was estimated at 1,500 kilograms (3,300 lb).[1] At over 19 hands (76 inches, 193 cm), a Shire gelding named Goliath was the Guinness Book of World Records record holder for the world's tallest horse until his death in 2001.[2]
