Well, the definition of “perfect” is relative to your need and budget. But the ideal capacity of a transportable hoop base should be 35 gallons to ensure the stability of the hoop if the adults and young players are going to play. You will find hoops having more than 35-gallon capacity. The bigger is the better, but we think 35 is the ideal number. For kids, you can even go for the base capacity of 27 or 10 gallons.
