Most regulation curling stones weigh between 38 and 44 pounds, with about 42 pounds (around 19 kg) being the most typical weight used in play.

Quick Scoop

  • Standard range: 38–44 pounds per stone.
  • Common “game weight”: about 42 pounds (roughly 19 kg).
  • In kilograms, the rules translate to about 17.2–20.0 kg including the handle.

That means each stone weighs about as much as a medium-sized suitcase packed for a long trip, which helps explain why players slide them rather than lift them.
