The difference between a short girth and a long girth does not directly depend on the discipline, but on the length of the saddle's billets. It is the saddle's configuration (short or long billets) that primarily determines the type of girth:
• Short girth: used with saddles equipped with long billets. This is the case for dressage saddles, some monoflap jumping saddles, or saddles designed with low and long girthing.
• Long girth: used with saddles with short billets, such as all-purpose saddles, many classic (dual-flap) jumping saddles, and some versatile saddles.

It is particularly beneficial for sensitive horses, but can suit many different types.

It mainly depends on the length of the girth straps. A dressage girth is a short girth. It can be used with any saddle equipped with long girth straps, provided the saddle's configuration allows it.
