By definition, a baseball is "9 to 9.25 inches or 22.86 to 23.495 centimeters in circumference." That means that the diameter is between 2.864788975 and 2.944366447 inches or 7.276564 and 7.478691 centimeters (an average of 2.904577711 inches or 7.377627 centimeters).

The weight is defined as, "between 5 and 5.25 ounces or 141.747615625 and 148.8349964063 grams."

An official soft baseball (or practice ball) still conforms to the official size and weight of the official hard baseball, but it has a synthetic leather cover with a sponge cork and rubber center. These are usually Official T-Ball practice balls. Higher league practice balls still maintain the official size and weight, but contain a full-grain leather cover with a wound cork and rubber center.
