What should be checked when assessing the fit of a saddle?

When assessing the fit of a saddle, the clearance over the withers is crucial because it directly impacts the horse's comfort and performance. A saddle that fits properly should have enough space above the withers to prevent pinching or pressure on that sensitive area, which could lead to discomfort or injury while riding. This clearance allows for the natural movement of the horse's shoulders and ensures that the saddle is not interfering with the horse's range of motion.

Evaluating other aspects, such as the horse's coat color or the type of girth used, may be somewhat relevant but do not directly affect the fit of the saddle. The length of the stirrups is a matter of rider positioning and comfort rather than saddle fit. Therefore, proper clearance over the withers is an essential factor in ensuring that the saddle is well-fitted and appropriate for the horse.
