Frequently Asked Questions

What sizes do the Knockerballs come in?

The Knockerballs come in 4 sizes Small – This lightweight tiny ball is best for ages 2-6 who won’t be ‘playing’ bubblesoccer – this is just for rolling around and light bumps with parent supervision or guidance by our licensed and trained Affiliate locations. Medium – Ok, we can start playing some games with these balls. This is best for ages 6-12 and under 5 feet of height. Although some kids vary in size, weight and height it is best to ask the trained provider for their recommendation. Large – This will be best for anyone over 5 feet and over 12 years old. Before getting started make sure the players straps are adjusted properly and that there is a minimum of 8-12” inches of room above their head to the top of the ball. XL – This is for the larger players that are over 6 feet and over 200 lbs. It is important before playing to go over the safety rules and watch the training videos on the Do’s and Don’ts of how to play Knockerball. When playing it is also important that players on the field are the same size and athletic ability. We do not recommend kids and adults/teens playing at the same time. Remember, this is supposed to be fun, so lets keep it that way!
