Frequently Asked Questions
Are you sure this is right? It says I need many fewer balls than I expected.
You might be putting the diameter in the radius field. The radius is half the diameter, so if you're looking at 3" diameter balls, put 1.5 where it asks for radius.
Do you know where I can buy some playpen balls?
No, I don't. Sorry! If you find a supplier you like, let me know and I'll put a link here.
Is there a metric version?
Yes! Berge made it, and it's here.
Can I ask you more questions/send you pictures of the ball pit I made with this calculator/buy you a beer?
Sure! Shoot me an email: email@example.com
