Baseball · WBSC / Rule 1–3
The game and playing field
WBSC · 2025–2026In short
How WBSC baseball is played and how the diamond is laid out.
The diamond
Teams alternate batting and defending, aiming to score more runs by completing the bases in order. The standard diamond has 90-foot sides; the pitching rubber is 60 feet 6 inches from home plate. First, second and third base are 15-inch squares. The event table provides smaller dimensions for the youngest category.
Equipment and safety
Bats, balls, gloves and uniforms must meet the equipment rules. Protective helmets are required, and catchers need the prescribed protective equipment. Event-specific bat approvals and helmet requirements appear in the appendix; an approved adult bat or helmet is not automatically suitable for every youth competition.
Independent explanations and translations, not official federation publications. Based on the supplied WBSC Official Rules of Baseball 2025–2026, including its event-specific appendices. References use physical PDF pages. Explanations are condensed; the supplied edition and its stated competition conditions determine scope.
