Much of the origins of English and Western riding styles are defined by the practicality of their saddles. Here are some key differences between the saddles and how they correlate back to their respective style.
Western riding:
Western riding has its roots from cowboys in the west. Western style saddles are deeper and usually a little bit more comfortable due to the fact that their original purpose was for long hours working on the ranch.
Another key element in the Western saddle is the horn on the front. Also tracing back to the West, this was used to hold onto while roping cattle and after it was caught, it is used as a place to hang the rope.
English riding:
Unlike Western saddles, English saddles are not as deep nor do they have a horn. The reason for this is because English riding is a lot more formal and is used for jumping. The jumping requires the rider to lean forward a lot more so the horn would pose a problem.
The frequent jumping also alters each of the saddles’ styles. English saddles have a lot of padding for the knees to assist with the force of the jumps.
Overall, the tack you use while riding your horse definitely helps you determine what style you will be riding with. However, having a well-trained horse and being a good rider will help you in whatever discipline you choose.
