The size of a volte will vary between horses, based on their stride length and their training.
However, a horse should not be pressed to perform a smaller circle than is comfortable for him, as it will sacrifice balance, relaxation, and impulsion.
The volte was traditionally 12 strides long (using the inside hind leg) in circumference, resulting in a circle 10–15 meters in diameter.
[1] First developed by Saunier, leg-yields are sometimes incorporated into voltes, with the horse's nose facing the inside of the circle.
Additionally, de la Guérinière developed "square voltes", which are not commonly practiced today.
