The average dart weighs 23 grams. Darts below 23 grams are generally considered light arrows, and darts starting from 24 grams are considered heavy. For an inexperienced and starting out dart player, it is advised to start with 24 grams or heavier. The darts then tend to wobble less than what may be experienced with light darts. As you become a more experienced darts player and your technique improves over time, you can try lighter darts.
