Miniature Horse vs Pony - Size Matters...

What determines whether your little horse is a miniature horse or a pony? When it comes to little horses, it all comes down to miniature horse or pony height. Miniature horses (aka mini horses) are smaller than ponies. Miniature horses are no taller than 38 inches measured at the last mane hair. The American Miniature Horse Association classifies heights using “A” and “B”; whereas the American Miniature Horse Registry classifies heights using “Over” and “Under.” Height divisions for miniature horses as measured at the last mane hair are:

• A size or Under minis are no taller than 34 inches
• B size or Over minis are over 34 inches but no more than 38 inches 

 
Ponies are over 38 inches to no more than 58 inches (or 14.2 hands) measured at the tallest point of the wither. The pony heights listed below are how tall the horse is at maturity or 3 years and older. The American Shetland Pony Club breaks out the height divisions as follows:

• Foundation Shetland is no taller than 42 inches
• Classic American Shetland is between 42 and 46 inches
• Modern American Shetland is between 43 and 46 inches
• American Show Pony is no taller than 48 inches with no minimum height requirement
• National Sport Performance Pony has three divisions
  • Small is no taller than 42 inches
  • Medium is 42 to 50 inches
  • Large is 50 to 58 inches

 
So keep this in mind when you are purchasing your horse. If you want to compete in a specific divisions or classes, it is wise to have the horse measured by someone who is experienced in measuring horses prior to purchase. This will give you confidence that your little horse can compete or participate in the events and activities you want to attend. Whether you decide to purchase a miniature horse or pony, either will give you many enjoyable years of companionship no matter what your discipline.
