The Joint Measurement Board (JMB) was established over 80 years ago by the major equestrian organisations of the day. It is a not-for-profit organisation and dedicated to the accurate measuring of the relaxed height of horses and ponies.

The JMB is paperless. All official JMB measurements will be available for inspection on our on-line searchable database.
