Saddles should fit riders properly in which aspect?

When considering how saddles should fit riders properly, the correct answer focuses on the aspects that directly impact the rider's comfort and effectiveness while riding.

The fit of the stirrups is essential because they allow the rider to maintain balance and control. Properly adjusted stirrups ensure that the rider can effectively use their legs for cues, support, and stability while riding. If the stirrups are too short or too long, it can lead to discomfort and hinder the rider’s ability to maintain proper posture and position.

While other aspects, such as seat height and panel width, are also important, the correct answer highlights stirrups as a critical element for rider comfort and functionality. Seat height helps ensure that the rider can sit comfortably and securely in the saddle, but stirrup length has a direct impact on the rider’s position and ability to effectively communicate with the horse. Panel width is significant for the fit of the saddle on the horse rather than the rider. Hence, the focus on stirrups reflects a more immediate concern for the rider's connection and comfort while riding.
