How big and how heavy is each sport's ball?

Where the data comes from

Each point is one ball, read from the rules of the body that runs its sport. Where a rule gives a range, the point is its middle; golf's rule sets only a largest mass and a smallest diameter, so its point is those two limits. A diameter is turned into a circumference (π × diameter), and inches and ounces into centimeters and grams. Bowling (about 68 cm around and 7,257 g) is left out because it would need a log axis. The values are calculated by Unlabeled; only the measurements are taken from the rule books, not their text.

The twelve rule books, with the limits read from each:

• Golf: diameter at least 42.67 mm, mass at most 45.93 g. R&A rules

• Field hockey: circumference 224 to 235 mm, mass 156 to 163 g. FIH rules
• Baseball: circumference 9 to 9.25 in, mass 5 to 5.25 oz. MLB rules
