Competition boules must meet specifications set by the FIPJP. They must be hollow and made of metal (usually steel) with a diameter between 70.5 and 80mm and a weight between 650 and 800 g.
Leisure boules are boules that do not meet the FIPJP standards for competition boules, but are less expensive than competition boules and completely adequate for "backyard" games. Unlike competition boules, leisure boules are a "one size fits all" affair — they come in one weight and size.
When purchasing competition boules, a purchaser has a choice of a number of characteristics of the boules, including the size, weight, and hardness of the boules, as well as the striations (patterned grooves on the surface of the boules).
· A player can choose a boule whose size fits the size of the player's hand.
· The weight and hardness of the boule depends on the player's personal preference and playing style.
· Pointers tend to favor smaller, heavier, and harder boules, while shooters tend to favor larger, lighter, and softer boules.
