Are you wondering what size girth your horse needs? Most horses fall between a size 28inch – 34inch, but you can calculate for your horse. Figuring the girth size is a simple process with a tape measure and calculator. Asking someone to assist you makes it a bit easier and eliminates trying to wrangle around the horse.
With your horse standing on a level surface and all treats fully digested, pass the tape measure around his/her body where the girth will rest. Make the two ends meet and pull it snugly. Take a look at the number. This is your horse’s heart girth.
Use this formula to calculate your horse’s girth size:
HEART GIRTH MEASUREMENT DIVIDED BY 2, THEN SUBTRACT 3
Example: (70/2) - 3 = 32”
You may need to round, as many girths only come in even sizes. This will give you a good estimate for ordering the correct size. You’ll want around 8-10 inches between your cinch and saddle.
When it comes to determining the size cinch your horse will need, you must accurately measure your horse. Use a tape measure to determine the space from one rigging ring to the other and then subtract 16” to account for the space that the latigos will stretch down.
When fitting the actual cinch on your horse, place the middle of the cinch behind your horse’s front legs and allow the ends of the cinch to drop about 8 inches from the bottom of your saddle’s D-rings when fastened with the latigos.
