The National Federation of State High School Associations (NFHS) has a committee that writes the rules for many high school matches. The physical specifications of an NFHS ball are very similar to those of an NCAA ball, with the circumference being the only difference. While any NCAA ball could be used in a NFHS game (if the NFHS authentication markings appear), the reverse may not be true, depending on the actual circumference of the ball.
SECTION 2 THE BALL
ARTICLE 1. The ball shall be spherical with a laceless molded cover of 12 or
more pieces (all of which shall be white) of genuine or simulated smooth leather
(not suede). It shall measure at least 25 inches but no more than 27 inches in circumference,
with a weight of 9-10 ounces when inflated with 4.3 – 4.6 pounds
per square inch of air pressure.
ARTICLE 2. The home team shall provide game balls.
ARTICLE 3. The ball shall include the NFHS Authenticating Mark. The mark can
be displayed in either authorized NFHS format.
A current list of NFHS authenticated products can be found on the Web site, www. nfhs.org.
