On average the Belgian will grow to weigh slightly over 1 ton or 2,000 pounds. Currently, the world's tallest Belgian Draft is Radar, a gelding foaled in 1998 in Iowa. He stands at 19.3½ hands high, which means he is 6 feet 7½ inches (2.02 metres) tall at the withers, and weighs over 2,400 lb (1,090 kg).
The world's largest Belgian Horse was named Brooklyn Supreme, who weighed 3,200 pounds (1,450 kg) and stood at 19.2 hands (1.98 m).
They are able to pull tremendous weights. At the National Western Stock Show in Denver, Colorado, a team of two horses in the Heavyweight class pulled 17,000 pounds a distance of 7 ft 2 in (7,700 kg a distance of 2.18 m). The team of Belgians weighed 4,800 pounds (2,200 kg). At the Iowa State fair, the heavyweight champions in the pulling contest pulled 14,600 pounds the complete distance of 15 ft (6,690 kg, 4.6 m). The team consisted of one Belgian and one Percheron weighed 3,600 pounds (1,600 kg).
Although the overall percentage of draft breeds among American horses has declined, the number of Belgians has increased.
