The WNBA ball has a minimum circumference of 28.5 inches (72.4 cm), which is one inch (2.54 cm) smaller than the NBA ball. The WNBA ball is also 1/4-inch (6 mm) thinner.
The WNBA ball is designed to be more flexible and easier to handle for players. This allows for more action shots and diving plays compared to the harder-ball game of the NBA.
The WNBA ball does not have the rubber composition of the NBA ball, which is why it is called a "hardwood" instead of a "gameday" ball. The WNBA ball has eight panels and two logos on it, one on each side. There is text printed around the edge of the ball, including the word "WNBA."
Each year, the WNBA announces that its ball will no longer be available for purchase by the public. Instead, it will be used in games during regular season play. The ball is replaced because it becomes worn out from use over the course of several games.
The ball is smaller because it needs to be for display purposes only. To actually play basketball with it, you would need a larger ball.
The legal framework The WNBA ball has a minimum circumference of 28.5 inches (72 cm) and weighs 20.0 ounces (570 g), which is 1 inch (2.5 cm) smaller and 2 ounces (57 g) lighter than the NBA ball. Since 2004, this size has been utilized for all senior-level women's full-court basketball contests across the world.
In addition to these sizes, there are balls that are designed specifically for use in youth sports. These balls are usually between 1 and 3 inches in diameter and may be white or black. They are generally less durable than adult-size balls and should not be used when scuffing the surface is permissible.
There are also balls that are designed for use in beach volleyball. These balls are typically much larger (about 12 inches in diameter) and weigh about 22 pounds (10 kg).
Finally, there are balls that are designed for use in indoor soccer. These balls are usually inflated to about 10 pounds per square inch (psi), which is about as heavy as an average deflated soccer ball will be after several matches.
Indoor soccer balls are available in sizes similar to those used in outdoor soccer, with differences based on how tightly the ball is sewn together (the higher the quality, the tighter the stitch work). Indoor soccer balls also tend to be either white or have dark markings (blackballs are used by some teams but are not common).
The size of a basketball in the National Basketball Association (NBA) is 29.5 inches (75 cm), with a maximum circumference of 29 inches in the Women's National Basketball Association (WNBA). NCAA, NBA, or WNBA sized balls are typically used in high school and junior leagues. Balls can be as large as 33 inches (84 cm) in some countries like Canada.
Balls are measured by inserting a ball marker through the center to mark the diameter of the ball. The length of the stick determines how many inches the ball will roll. A standard basketball is.975 inches in diameter; thus, a three-and-a-half-inch ball will roll about 100 feet; while a four-inch ball will travel 150 feet. There are also.944-inch and 1.02-inch balls available for use with special needs players.
In college basketball, balls are usually between 32 and 36 inches in diameter (81 and 91 centimeters). In elementary school and junior league play, balls can be as small as 28 inches in diameter (72 cm), but are usually 30 inches (76 cm).
The weight of a basketball ranges from 454 to 494 grams (16 to 18 oz).
Basketballs are made of vulcanized rubber and are heat-treated before being colored red or white.
The diameter of a typical NBA basketball is from 9.43 and 9.51 inches. The basketball in the WNBA has a diameter of 9.07 to 9.23 inches. Basketballs used in the NCAA range in size from 9.39 to 9.55 inches for men and 9.07 to 9.23 inches for women.
Basketballs are measured across the widest point of the ball; the manufacturers then take into account the overall weight of the ball to arrive at its circumference. This is usually done by pouring the ball through a template that matches the required diameter, which allows them to calculate how much rubber to use. A standard basketball weighs between 26 and 29 grams (1 oz). Balls used in practice sessions or games with limited time limits should be heavier than those used in longer contests.
College basketballs are typically less thick around their equator than those used in the NBA. This is because the ball is more likely to become inflated beyond what is acceptable by coaches and players in the NCAA. While this may be desirable in terms of court play, it makes manufacturing the ball more difficult due to its having to be as close to a spherical shape as possible. Coaches prefer that college basketballs aren't too hard nor too soft, so they tend to be closer to 27 grams (1 oz) than to 30 (1.19 oz).
