When assessing the factors that impact a horse’s comfort and performance, the bridle is likely not the first thing that comes to mind. However, bridle fit can make an enormous difference in a horse’s comfort and response to a rider.
During her presentation at the 2024 AAEP Convention, Hilary Clayton, BVMS, PhD, DACVSMR, FRCVS, a sports medicine practitioner and accomplished dressage rider, explained that the headpiece is the weight-bearing part of a bridle. With locomotion, the headpiece experiences a cyclic pattern of pressure: When the head and neck are at their lowest point and start to rise, more pressure occurs. Ideally, force is distributed through the headpiece over a wide area to reduce pressure.
Bridle Fit Considerations
It’s also important that the bridle doesn’t place pressure on the aural cartilages of the ear. The crownpiece is typically shaped to avoid this sensitive area, but the tack must sit at the right place for the individual horse. If leather or padding over the poll is removed to make a narrower strap, it can create uncomfortable edges and concentrate pressure around the ears. In contrast, a headpiece with too much padding is difficult to stabilize.
Clayton said the ideal is an “anatomical bridle” with a monocrown headpiece; all the straps for the noseband, throatlatch, and bit hangers are attached to the crown piece, which exerts even pressure over the poll. The cheekpiece suspends the bit from the headpiece and transfers the weight to the poll. The buckles should sit at eye level over the soft underlying masseter muscles rather than over the temporomandibular joints.
The browband, which sits across the forehead in front of the ears, helps stabilize the bridle. You should be able to fit one or two fingers between the browband and the face, which prevents it from pulling the crown piece toward the ears. A curved or V-shaped browband gives more laxity.
The throatlatch helps keep the bridle on the horse’s head. You should be able to fit four fingers, held perpendicular to the horse’s face, underneath the throatlatch.
Fitting the Bit
Fitting the bit with one or two small wrinkles at the lip commissures achieves the best stability. A bit that is too loose does not allow a rider correct contact with the mouth; if too tight, a horse is likely to develop ulcers in the lip. The FEI is now evaluating the mouth prior to competition to check for oral injuries.
FEI Two-Finger Rule
Clayton explained that in dressage, judges will penalize the rider if the horse’s tongue is visible. Consequently, some riders adjust the noseband very tightly. On January 1, 2025, a new FEI two-finger laxity rule went into effect. Ring stewards will use a specific gauge to measure this; the gauge must be able to slide all the way beneath the noseband for the horse to pass.
