What is the weight of a man's Olympic discus?

A man's Olympic discus weighs 2 kilograms (4.4 pounds). This is the standard senior men's discus used in Olympic competition, including the men's discus throw event.

The discus is a round, lens-shaped implement traditionally made with a metal rim and a wooden or synthetic body. Its diameter is about 22 centimeters, although its shape and thickness are also regulated so athletes compete with equipment meeting consistent specifications. The 2-kilogram minimum weight is set by international athletics rules.

A common mix-up is the women's discus, which weighs 1 kilogram and is smaller, at roughly 18 centimeters in diameter. Younger athletes and masters competitors may also use lighter discuses depending on age category, so not every discus seen in training weighs 2 kilograms.

The event has ancient Greek roots, but the modern Olympic discus throw developed under standardized track-and-field rules. It was included at the first modern Olympic Games in Athens in 1896. Athletes rotate inside a throwing circle before releasing the discus, converting speed from the turn into distance.
