Jockey weights explained

Jockey weights are the total assigned racing weight a horse must carry, comprising the jockey, their equipment and any lead weights needed to reach the required total.

Minimum riding weight (flat, from 2022)
8 st 2 lb4
Standard top weight (flat, from 2022)
10 st 2 lb4
Apprentice claim (initial)
7 lb2

Key points

  • Before a race the jockey weighs out with full equipment; if under the required weight, lead is added to the saddle cloth.13
  • After the race the jockey weighs in; being more than 1 lb under the weigh-out weight disqualifies the horse.5
  • Apprentice and conditional jockeys can claim a weight allowance that reduces as they ride more winners.2
