Knockerball Sizes

and Safety Features



Knockerball® is a single chamber inflatable bubble with inner handles and adjustable shoulder straps. Knockerballs® range from 1.2 Meters (Medium) to 1.5 Meters (Large) and the size or fit is predicated on your height.

Sometimes waist size will make the ball feel tight, so an upgrade in size would be needed, while others may feel more comfortable in a smaller size.

When ordering your sizes, use this as a guide, don't worry - we'll try to bring a few extra sizes just in case.
Our Knockerballs should fit anyone over the age of 6 depending on your height.
