In 1959, the NCAA goalposts were widened to 23 feet 4 inches (7.11 m), the standard width for high school posts today. In 1991, the college goalposts were reduced in width to 18 feet 6 inches (5.64 m), matching the width of NFL goal posts. For the 1991 and 1992 seasons, this meant potentially severe angles for short field goal attempts, since the hashmarks were still located 53 feet 4 inches (16.26 m) apart.
There are no standards for sizing of youth goals and every league sizes them differently. The FIFA Laws of the Game specify that a goal should be 8 yards (7.32 m) wide and 8 feet (2.44 m) tall. The posts themselves must be 5 in (12 cm) or less in diameter. Note that these are FIFA requirements. Games played outside FIFA affiliated competitions do not necessarily comply with international standards.
