Based on package dimensions from an Amazon listing for a 6-pack of 16.9 fl oz vitaminwater bottles, the height is approximately 7.47 inches. This measurement refers to the height of the package when the bottles are arranged together. It is likely the individual bottle is somewhat shorter, but still close to that dimension.
It is difficult to say with absolute certainty the height of every vitaminwater bottle, as slight variations may exist based on bottle design or manufacturing tolerances. However, this measurement provides a reasonable estimate.
