How to choose the basketball size that suits oneself

Basketball is divided into the following four standard sizes:
(1) Ball number 7, basketball number 7 is a standard men's game ball with a weight of 600-650g, circumference of 75-76cm, diameter of 24.6cm, 29.5 inches. Purpose: formal and professional games (2) Ball number 6, basketball number 6 is a standard women's game ball with a weight of 510-550g, circumference of 70-71cm, diameter of 22.6cm, 28.5 inches
(3) Ball number 5, basketball number 5 is a youth game ball: weight 470-500g, circumference 69-71cm, diameter 22.0CM, 27.5 inches
(4) Ball number 3, basketball number 3 is a children's game ball, weighing 300-340g, with a circumference of 56-57cm and a diameter of 18.1cm and 25.5 inches
Finally, in my personal opinion, basketball is also the most important thing. The ball is a sphere, and the most important thing is to be round. Different manufacturers have different strengths, and even the same ball may have individual quality problems. The first thing we do when we receive a ball is to use our naked eye to observe whether the ball is round. If there are bulges or deformation in certain positions, then even the best brand and material are unqualified basketball balls
