Every serious question about bocce balls eventually reduces to one thing: what size do you actually need. Regulation tournament play uses one specific size. Backyard casual play uses another. International volo play uses a third. Getting the wrong size does not just cost you money, it produces a game that plays differently from what your court and rules were designed for. This is the complete 2026 size chart with official dimensions, weights, pallino sizes, and clear guidance on matching ball type to court and skill level. For coverage of how these specs affect gameplay directly, see our diameter and weight specs guide.
Key Takeaways
- 107mm is the American tournament standard used by USBF, most Italian-American clubs, and league play across North America. Weight is 920 grams per ball.
- 110mm and 114mm are international volo sizes used in Europe and at some FIB-sanctioned events. Weights range from 900 to 1200 grams.
- 73mm metal petanque boules are used for the boules family of games. Weights range from 650 to 800 grams. Not interchangeable with bocce balls.
- Backyard mini sets (50 to 90 mm) are designed for family play and grass surfaces, not regulation courts. Sold as recreational sets, not tournament equipment.
- The pallino diameter varies by ball size: 40 to 50mm for 107mm American, 35 to 60mm for volo sizes, and 30mm for petanque.
The official size chart across every regulation ball type
Bocce ball sizes have been standardized by three governing bodies whose specifications rarely change. The United States Bocce Federation defines American tournament play. The Federazione Italiana Bocce defines international bocce standards. The Confederation Mondiale des Sports de Boules defines the broader boules family including petanque. Coverage of the current spec set across all three bodies in the USBF equipment reference tracks with what practitioners see: the specs are stable and buying to spec is straightforward once you know which discipline you play.
The 107mm American tournament ball is the most common regulation size in North America. Diameter is exactly 107mm, weight is 920 grams (with a tolerance of plus-or-minus 5 grams per ball across the set), and construction is hard-shell resin with a decorative surface. This is the ball used at every USBF-sanctioned tournament and at nearly all Italian-American social clubs across the US. Pallino diameter for 107mm play ranges from 40 to 50mm depending on the specific tournament rules.
The 110mm and 114mm sizes are the international volo standards used in Italian and European FIB-sanctioned play. Diameters are exactly 110mm or 114mm, and weights vary by manufacturer within the FIB tolerance range of 900 to 1200 grams. The larger 114mm ball is common in volo Italian play where the game requires airborne throws with heavier balls that hold their line through the air. Coverage of the size differences at international competition in Federazione Italiana Bocce equipment materials confirms the 110mm and 114mm sizes are not interchangeable at sanctioned play.
The 73mm metal petanque boule is the boules family standard. Metal construction (chrome-plated carbon steel typically), weight range from 650 to 800 grams, and diameter of exactly 73mm. The pallino equivalent (called the cochonnet or jack) is 30mm and is usually wood or plastic. Petanque balls are not bocce balls: they are metal, smaller, and lighter, and playing bocce with petanque balls (or vice versa) produces a fundamentally different game.
Mini backyard sets range from 50mm to 90mm in diameter and are sold as family recreation equipment, not regulation gear. Construction is typically softer plastic or resin, weight is well below regulation, and the balls are designed to work on grass rather than groomed courts. These sets are excellent for family play with kids and are the right entry point for most backyard first-timers. They are not appropriate for league or tournament play, and mixing mini balls with regulation ones produces an inconsistent game.
Choosing the right size for your court, league, and skill level
The right ball size depends on three questions: what court you play on, what discipline you compete in, and where you are in your skill development. Match honest answers to those three and the choice is clear.
If you play at a US Italian-American social club, at a USBF-sanctioned tournament, or in any league that uses American rules, buy 107mm balls. This is the North American default and the answer for probably 80 percent of American players. Coverage of the US club scene in Britannica's reference materials on bocce confirms 107mm as the dominant US size. For coverage of the specific 107mm ball options, see our 107mm regulation set guide.
If you play in an international federation league, if your club follows FIB rules directly, or if you compete in volo Italian outside the US, you need 110mm or 114mm balls matched to your league's specific rules. Confirm with your league before buying because the sizes are not cross-compatible at competition level, and a set of the wrong size cannot be adjusted to fit.
If you are shopping for a backyard family set primarily for casual play with kids or non-serious adults, a mini or recreation-tier set is often the right pick. These sets are cheaper (under $100), designed for grass surfaces, and work well for the actual use case: kids learning the game, families barbecuing, occasional friends dropping by. Buying regulation-tier balls for backyard grass play is possible but overspecified for the use case. For coverage of the recreation-tier options, see our beginner set guide.
If you play petanque or want to try boules-family games, buy 73mm metal boules from a petanque-specific supplier. Boules balls do not play like bocce balls (they are lighter, smaller, and metal) and using bocce balls for petanque is not workable at any competitive level. Petanque and bocce are cousins, not the same sport, and the equipment reflects the distinction.
Skill level matters less than court and league because regulation ball size is defined by the sanction, not by player experience. A first-year league player uses the same 107mm ball as a 20-year veteran because the league requires it. What changes with skill is the quality tier within the size: beginner-tier 107mm balls have wider weight tolerances and less consistent surfaces, while tournament-tier 107mm balls hold tight weight tolerances that make strategy visible in results. For coverage of the quality tiers within regulation sizes, see our 107mm vs 110mm vs 114mm comparison.

Size, weight, and material tolerances that actually matter
Beyond the diameter and weight specs, three tolerances separate tournament-grade sets from casual sets. First is ball-to-ball weight consistency within a set. USBF-sanctioned play requires all 8 balls in a set to weigh within 5 grams of each other. Recreational sets often have variances of 15 to 25 grams between balls, which produces inconsistent rolls even when the thrower does everything right. If your set has weight variance, half your strategic execution is masked by equipment noise.
Second is surface consistency. Regulation balls have a decorative pattern (marble, solid color, or engraved) but the surface itself is uniform within a few thousandths of an inch across the set. Cheap sets have pit-and-flash molding defects that catch on court surfaces and produce unpredictable roll paths. A visible molding line is a sign the set is not tournament grade.
Third is roundness tolerance. Regulation balls are round within one millimeter of true. Recreational balls can be up to three millimeters out of round, which shows up as wobble at low speeds and roll drift on flat courts. This is the tolerance you cannot see without measurement equipment but that shows up as "why does this ball never roll straight" in actual play.
Material matters at the margin. Hard-shell resin is the standard for regulation balls because it holds its shape and does not deform under repeated impact. Cheap sets sometimes use softer plastic that dents visibly after a season of play, which changes the ball's weight distribution and therefore its roll. Metal is only used for petanque; bocce is always resin. Coverage of the material specifications across regulation levels in the USBF equipment materials confirms hard-shell resin as the durable choice.
The last spec that matters is the pallino. A worn or wrong-sized pallino changes the target geometry of every frame. Regulation pallinos are 40 to 50mm for 107mm play, high-visibility color (white or bright yellow), and hard-shell construction. If your set came with a small or worn pallino, replace it before it starts affecting frame outcomes. For coverage of pallino replacement, see our pallino replacement guide.
