Question

What are the minimum and/or maximum height/weight requirements for horse jockeys?

Answer 1

There is no weight limit as long as they can make the weight assigned by the race stewards for the horse they are riding. Some jockeys are too light and need to add weights to the saddle in order to hit the assigned weight. Heavier jockeys can make the assigned weight with just their body weight and nothing more.

Answer 2

There is no height requirement just weight. A jockey can't weigh more than 112lbs.
