To begin with, when building stalls you can choose between box (loose) stalls and tie (standing) stalls. With box stalls for an average size riding horse the minimum measurements of the stall should be at least 3×3 meters to 3,6×3,6 meters. This is only the minimum standard and it is recommended that you build a bigger stall if possible. These measurements of horse stables have been set by the Canadian Agri- Food Research Council, Recommended Code of Practice for The Care and Handling of Farm Animals. With tie stalls the minimum measurements are 1,5 me- ters wide and 2,4 meters long. The stall should be wide enough so the horse can lie down comfortably
