The Groningen standard calls for a correct horse; heavy, with the legs about half the horse's height, and a rectangular frame, with the body from point-of-shoulder to point-of-buttock about 10% greater than the height of the horse at the withers. The topline is level, muscular neck set on fairly high, and the loins and haunches are broad and powerful. The head is workman-like and the hooves large and sound. Ideally, the Groningen stands between 15.3 and 16.1 hands high at the withers.
