For example, are you asking:
* Is a certain horse stall height safe for a horse? This depends on the horse's size and breed, as well as its intended use.
* Is a certain horse stall height compliant with regulations? Building codes and regulations vary depending on location.
* Is a certain horse stall height suitable for a particular horse? Some horses might be more prone to injuries or have specific needs that require a different stall height.
Once you give me more information, I can help you figure out if the horse stall height is appropriate.
