Measure for Girth Size

• 1). Stand your horse on a level surface to obtain an accurate measurement.
  
  
• 2). Wrap the tape measure over the horse's withers (the point where the neck and back meet). Ask your assistant to hand the tape back to you under the horse's barrel (the area just behind the front elbow).
  
  
• 3). Pull the two ends of the tape measure together tightly. This measurement is the horse's heart girth in inches. The tape measure will be at a slight angle with the top point at the withers being a few inches further back then the bottom point at the belly.
  
  
• 4). Divide the heart girth measurement by two. Subtract three from the answer. (Example: Heart girth is 71 inches. Divide by 2 gives you 35.5 inches. Subtract 3: the answer is 32.5 inches)
  
  
• 5). Round the number up to the next even whole number since girths only come in even numbers. The girth size would become 34.
