7 is the youngest age
7 for pbs4k or 50 cal paintballs (field paint only) private group with light weight guns and 10 for 68 cal aka the normal size ball you can buy at normal paintball stores. I recommend waiting till they are ten so it is more likely they can carry the gun and not cry. In the mean time spend the money on some nerf guns and ammo and go to a public park
7 for paintball soft
I want to say 9 years old look up the website they get all the information in there
