While cheaper balls are crushed more easily, your weight is always distributed among hundreds of balls, when you're in the ball pit.It's pretty difficult to crush a ball pit ball unless you stand on one directly.

How many ball pit balls do I need?

This really depends on a wide variety of factors - ball diameter, packing density, desired ball height. We've made a ball pit ball calculator for you that does the hard work and gives a rough estimation of how many balls you'll need. To give you a sense, a 4.5x5.5x2.5 foot ball pit needs 3500 balls to be able to completely immerse a person. However, the diameter of a ball plays an important role in the total volume of balls needed.

How big should my ball pit balls be?

The diameter of the balls (the distance between the two furthest points on a ball) has a big impact on how many balls you'll need. If you get balls with a smaller diameter, they'll be slightly more sturdy, but you'll end up paying a lot more, as you'll need more balls to fill the same volumne in your ball pit. For example, it only takes 52 3 1/8" balls to fill up a cubic foot. It would take 280 2" balls to fill the same space. While you pay more per ball, the cost is offset by the total number of balls needed.

The recommended ball diameter is 2.5" (~25mm) to 3 1/8" (80mm). Anything less, and the cost of a ballpit increases exponentially.
