    How to choose the right petanque boule

    You should choose your petanque boule based on several factors.

    Your playing style (pointer, shooter, all-rounder) will determine:
    - the required bounce quality (hard, semi-soft, soft or very soft)
    - the weight of your boule (heavier for pointers and lighter for shooters)

    The size of your hand will determine the boule's diameter.

    What does hardness mean for a petanque boule?

    The boule's hardness is expressed in the ROCKWELL HRC unit or in kg/mm². For example, 39 HRC corresponds to 124 kg/mm². The higher the number, the harder the boule. The harder the boule, the less likely it is to get damaged, and the higher its elasticity, and vice versa. Regular players who use soft boules should consider frequently changing their boules to avoid undermining their game.

    How to clean your petanque boules?

    After each match, wipe off dust with a clean cloth. Once a month, oil your petanque boules to prevent them from rusting. Cleaning regularly lengthens the lifespan of your petanque boules while also ensuring the quality of your match.

    How competition-approved DECATHLON boules are made

    Our competition boules are hollow. These are the steps of our manufacturing process: - A lump of steel heated to +/- 1000 C° is flattened and then stamped or forged into a hemisphere - These hemispheres are machined inside, welded together, and rotated until they are spherical. - The boule is then engraved, baked, and dipped into water, which will determine its hardness. - Finally, they are polished or varnished and then inspected.
