USG USG Trust Bitless Bridle

While bridle sizes generally will fit horse sizes according to the size chart, horse head sizes do vary, and you should test the bridle first to make sure it is a good fit.

When the bridle is on, there should be a hand’s width between the chin strap and the horse’s jaw, two fingers’ width between the noseband and the horse’s nose, and you should be able to fit two fingers under the browband. The browband must not be so tight that it pinches behind the horse’s ears, nor be so long that it pulls the bridle forward.
