The Andalusian is a medium-to-large horse that typically stands between fifteen and sixteen-plus hands and carries a compact, well-muscled frame. A standard twelve-by-twelve-foot stall is the minimum recommended size for this breed, though a twelve-by-fourteen or fourteen-by-fourteen stall provides noticeably more comfort, especially for taller individuals or horses that like to lie flat when sleeping. Cramped stalls contribute to stiffness, stress behaviors, and increased risk of casting.
Turnout space matters just as much as stall dimensions. Andalusians are active, social animals that benefit enormously from daily access to paddocks or pasture. A minimum of one acre per horse is a common guideline for continuous turnout, though the actual space needed depends on forage quality, soil drainage, and herd dynamics. Smaller dry lots of at least several hundred square feet work well as exercise paddocks when pasture is limited or when turnout needs to be restricted for metabolic management.
Ceiling height in barns should be no less than ten feet, and twelve feet is preferable. Andalusians are expressive horses that may rear or toss their heads when startled or excited, and insufficient overhead clearance creates a genuine injury risk. Doorways should be at least eight feet tall and four feet wide, with no protruding latches, bolts, or hinges at head height that could catch a mane or cause facial lacerations.
Aisle width in the barn should accommodate comfortable leading and grooming. A ten-to-twelve-foot center aisle allows two horses to pass safely and gives handlers enough room to manage a horse that sidesteps or swings its hindquarters. Narrower aisles increase the risk of kicks, crushes, and handler injuries, particularly during busy feeding or turnout times.
