6" cheek, 5.5" mouthpiece. This is one of my most popular bits. It is a good transition from the d-ring snaffle, allowing more stop and control. An excellent bit for introducing the curb strap. good for a horse with a light mouth. This bit is well balanced and light weight. The purchase on this bit is the same length as the shanks which helps with collection. Great turning bit and a fair stopper.
