The reins must be adapted to the size of the bit and the morphology of the horse's mouth.
A rein that is too short can create an overly direct and uncomfortable action, while a rein that is too long lacks precision.
Once in place, the rein should rest naturally, without pulling up or down when the reins are at rest.
The correct fitting is one that allows for progressive action, without excessive pressure points, and that allows the horse to remain relaxed and mobile in its mouth.
If the bit moves excessively or if the horse's mouth shows signs of discomfort, the adjustment should be reviewed.

The reins should always be oriented outwards to avoid any discomfort or rubbing. The reins must remain free, untwisted, and naturally follow the line of the bit. The reins should act without permanent tension; if the reins are constantly in use, it means either the action is too strong or the adjustment is unsuitable. The reins should never amplify the effect of the bit, but rather make it softer and more stable.
