-This completely depends on how your horse is built. -Our in-stock show pads measure 34”x42” and are the most popular size option that allows more of the pad to be seen. -Our in-stock ranch pads measure 34”x40”, this is the most popular in the ranch pads, it’s a bit smaller for the disciplines that require more leg contact while showing. -Most work/under pads are 32” in spine length, which allows 1” on the front and back for the pad to cover up the work pad. -If you have a smaller horse or a rider with shorter legs we can definitely customize the dimensions across the barrel of the horse to meet your requirements.
