The 12 by 12 Baseline for a Quarter Horse
The standard 12 by 12 foot stall became standard largely around horses like this one. A Quarter Horse typically stands between 14 and 16 hands, compact in the body but famously powerful through the hindquarters, and that footprint fits a 12-foot square with room to turn, lie down, and rise cleanly. A field shelter of about 12 feet in depth and 12 feet of width per horse gives the same usable space outdoors. Before treating the baseline as settled, though, measure your own horse: a tall, long-backed individual or one who weaves or box-walks may settle better with an extra two feet of length.
Floors and Footing for a Powerfully Built Horse
Quarter Horses carry a lot of muscle over a relatively compact frame, and they push off hard when they rise, turn, or react to something in the yard. Slippery stall floors are therefore a bigger problem for this breed than sheer floor area. Choose a level, non-slip surface, keep bedding even rather than banked into one corner where a hind foot can slide, and make sure a field shelter's standing area is drained and re-surfaced before it polishes into mud over stone. Doorways should be wide enough for those hindquarters to pass squarely, and the threshold level, so he is not stepping up and twisting at the same moment.
A Working Horse's Shelter Routine
Many Quarter Horses work in ranch, trail, or arena routines and come in damp with sweat or rain. A field shelter earns its keep on those days as a place to stand out of the wind while he dries, so position it where you can reach him easily with a rug or cooler rather than at the far end of the field. Inside a stable, good airflow above and around the stall keeps a worked horse comfortable without chilling him. If he lives out full time, the shelter plus natural cover and a rug in harsh weather is usually sufficient for this hardy, adaptable breed, provided the ground inside the shelter stays dry.
Sharing Shelter With Other Stock Horses
Quarter Horses are often kept in small groups of similar stock-type companions, and shared shelters work well when the frontage is wide enough for the group's pecking order. Allow roughly another 10 to 12 feet of width for each additional horse rather than expecting three horses to file into a single-horse shelter, and watch the lowest-ranking horse at the worst moment of a storm; he is the honest test of whether the cover is big enough. Scatter hay in separate piles outside or at opposite ends of a wide shelter so no horse has to choose between eating and keeping a wary eye on the boss.
Older Quarter Horses and Stall Comfort
As a Quarter Horse ages, the stall that suited him at eight may test him at twenty. Stiff joints make tight turns and deep, shifting bedding harder work, so an older horse often appreciates a slightly larger box, a shallower, firmer bed, and a shelter in the field placed on level ground he can reach without crossing a slope. Likewise, a mare and foal need a bigger foaling box than the everyday 12 by 12, arranged in advance. The dimensions in this article are the everyday answer for a typical adult, adjusted upward whenever the individual horse's age, size, or job says so.
