107mm bocce balls are the FIB international regulation size used in USBF-sanctioned league play across North America. The diameter is exactly 107mm, weight is approximately 920 grams per ball, and the construction is tournament-grade resin. A complete 107mm 8-ball set covers two teams of 4 balls each in contrasting colors plus a smaller pallino target ball. Pricing ranges from $273 for a basic 8-ball bundle up to $325 for an engraved EPCO tournament set with carry bag.
The 107mm size dominates competitive bocce because it's the FIB raffa specification, codified in the mid-twentieth century and unchanged since. If you plan to join a sanctioned league at an Italian-American club, a Pinstripes restaurant-bocce venue with league nights, or any USBF-affiliated tournament, you need a 107mm set. The smaller 73mm metal pétanque sets and larger 110mm/114mm Italian recreational sizes are not sanctioned for raffa league play. According to the United States Bocce Federation, the 107mm standard has held continuously since FIB codification and is required for every sanctioned event under USBF Open Rules.

Why 107mm is the regulation size
The 107mm specification traces from the 1947 founding of the Federazione Italiana Bocce and the standardization effort that followed across post-war Italian club construction. The 107mm diameter was chosen for raffa-style rolling play because it balances three competing requirements: heavy enough to roll true on stone-dust or decomposed-granite outdoor surfaces, small enough to manipulate one-handed at the throwing line, and large enough to cluster predictably around the pallino during scoring.
According to the Federazione Italiana Bocce, the 107mm raffa specification is the international tournament standard recognized by the Confederation Mondiale des Sports de Boules and by every national bocce federation that follows FIB rules. The USBF adopted the same standard for North American sanctioned play when it formed in 1976.
107mm size vs the alternatives
Three other sizes exist in active commercial production:
110mm: Italian recreational, weight roughly 1,100 grams. Used in backyard play on grass and for the volo-style throwing tradition in northern Italy. Not sanctioned for raffa league.
114mm: Italian volo tradition, weight roughly 1,200 grams. The largest active size, used in northern Italian volo competition and on rough outdoor grass courts. Not sanctioned for raffa league.
73mm metal: French pétanque, hollow steel construction, weight 650-800 grams. The French tradition, played underhand from a fixed circle rather than rolled along a court. Different sport, different governing body (FFPJP rather than USBF).
For backyard play without league plans, any of the four sizes works. For league play, 107mm is required. According to Encyclopedia Britannica's entry on bocce, the size variation across raffa, volo, and pétanque reflects regional tradition rather than equipment evolution; modern resin manufacturing supports all three sizes equally well.
