GUIDELINES FOR
DRESSAGE BITS

USEF/USDF COMPETITIONS
Please refer to USEF Dressage Rule, DR121 for the Saddlery & Equipment Rules. If you have a question regarding a bit that is not listed, please submit a picture of the bit to kbrett@usef.org.
Please be advised that this office only gives advisory opinions, not binding opinions, regarding the rules since ultimately it is the Federation Hearing Committee which applies facts and circumstances to the relevant rules and determines whether or not each fact constitutes a violation of the rules; and then only after a protest or charge of rule violation is brought before them. Nevertheless, the Federation is often asked to provide guidance regarding the rules and the Federation staff does try to be of assistance when the rules seem to have clear application to a described situation. It should be noted, however, that the opinion expressed by a USEF staff member would not be binding on the Hearing Committee.

HOW TO MEASURE YOUR BIT? THE DIAMETER OF THE SNAFFLE MOUTHPIECE The diameter of the snaffle mouthpiece must be minimum 10 mm diameter at rings or cheeks of the mouthpiece (exception: for ponies, the diameter may be less than 10 mm). The diameter of a bit is measured at the rings or cheeks of the mouthpiece.
MEASUREMENT OF A SNAFFLE BIT TO ALLOW TONGUE RELIEF The maximum height of the deviation is 30 mm from the lower part of tongue side to the highest part of the deviation. The widest part of the deviation must be where the mouthpiece contacts the tongue and must have a minimum width of 30 mm.
CORRECT BIT MEASUREMENT The lever arm of the curb bit must not exceed 10cm (length below the mouthpiece). If the curb has a sliding mouthpiece, the lever arm of the curb
