The mass is between 5 and 5¼ avoirdupois ounces; the circumference from 9 to 9¼ inches. This is only slightly smaller than the 1861 ball, which had 5¾ ounce and 9¾ inch maximums. It is covered by two pieces of white leather, formerly horsehide, but cowhide has also been permitted since 1975.


A round, solid wood stick no more than 42 inches long; maximum diameter 2¾ inches. The first 18 inches may be covered with material which improves the batter's grip. A curved indentation is permitted on the end of the bat, not deeper than 1 inch, with a diameter no greater than 2 inches and not less than 1. Bats may not be colored. Designs for solid laminated bats may be approved, but such a bat's performance must be no better than that of a solid wood bat.


The regulations on the sizes of gloves are extensive; for example, 17 measurements are taken of a fielder's glove.
