Six breeds that make a useful starting point for learning about horses are the Arabian, Thoroughbred, American Quarter Horse, American Saddlebred, Morgan, and Miniature Horse. This is an editorial selection, not a popularity ranking: horses differ in size, build, and common uses, and an individual horse’s temperament or suitability cannot be determined from its breed alone.
The ASPCA says there are more than 350 horse breeds around the world, a figure it published in 2021 without explaining its counting method. Its overview offers a practical introduction to six breeds readers may encounter at riding barns or in adoption listings. The descriptions below cover general breed characteristics—not guarantees about any particular horse.
Arabian
Arabians are known for stamina and versatility. The ASPCA gives a typical height of 14.1–15.2 hands and lists gray, bay, black, and chestnut among common colors. It also attributes more than 4,000 years of evidence of selective breeding to the breed.
Endurance is a prominent association, but Arabians are not limited to one discipline. The University of Kentucky lists trail riding, endurance, English and Western pleasure, cutting, reining, jumping, and dressage among their uses.

#1 Best Overall
Thoroughbred
The Thoroughbred is a lean, athletic breed that originated in England in the 17th and 18th centuries. It is strongly associated with racing, but not every Thoroughbred races, and racing is not the only activity for which the breed is used.
The ASPCA also names jumping, Western events, eventing, and dressage. Some retired racehorses go on to second careers in other disciplines.
American Quarter Horse
The American Quarter Horse is typically 14–16 hands tall, with a compact, muscular build and well-developed hindquarters, according to the ASPCA. The breed is associated with short-distance speed and cattle work.
Its uses also extend to English and Western shows and trail riding. That range reflects the breed’s versatility; it does not establish whether an individual horse is a match for a particular rider or activity.

Rank #3
American Saddlebred
The American Saddlebred is typically 15–16 hands tall. The ASPCA describes the breed as both spirited and gentle, and notes its distinctive smooth four-beat gait in addition to the walk, trot, and canter.
The ASPCA also names jumping and dressage as activities for Saddlebreds. A breed-level description cannot predict an individual horse’s behavior or training.

Morgan
Morgans are compact, with strong legs and bone structure, according to the ASPCA. Their range of uses includes riding and driving. The American Morgan Horse Association lists pleasure riding, ranch work, endurance, show, formal riding, and driving among the breed’s activities.
The association says, “The Morgan horse agreeably adapts to his owner’s lifestyle.” That is the breed association’s general description, not a promise about every Morgan.
Miniature Horse
The ASPCA gives a typical height of 8.5–9.5 hands for Miniature Horses. They are generally too small to be ridden by anyone other than very young children, so they are distinct from ordinary riding horses. In-hand competition—where the horse is shown while led rather than ridden—is one activity the ASPCA notes.
How to use breed descriptions when choosing a horse
Breed information can help you understand typical size, build, and common activities, but it is only a starting point. A suitable match depends on the individual horse’s temperament, training, and health, as well as the rider’s skill and intended activity. Assess those factors individually rather than treating a breed label as a measure of safety, beginner-friendliness, or suitability.
