Question: what is the average size and weight of a jockey?
Answer: As a rule of thumb, flat jockeys weight around 8 stone while jump jockeys can go a bit higher, up to 9 stone. In terms of height, there is no rule for how tall jockeys should be. But given that jockeys are so light-weighted, the average height tends to be somewhere in between 4”10 and 5”6 feet.
