Choosing the right size ball

The first step in purchasing a soccer ball is determining the proper size for your age group. Many soccer leagues have different size requirements, so be sure to check with your coach or organization to find out which is the proper size for the age group that the ball will be used with. Soccer balls for match use come in three different sizes which range from size 3 to size 5.

Size 5

• This is the international standard match ball for all ages 12 and older, including all adult play
• The size 5 ball weighs between 14-16 ounces with a circumference of 27-28 inches
