I always wanted to know. Why do they change size?

  • Big

  • Small

Is there a explanation? Because they change size a lot and it can't be the button in the middle (I did think the button change size until I saw half of a pokeball) because ash and his rival has a half of a pokeball each and both halves are tiny.

And tiny poke balls don't exist in the game AKA they don't change size in the games.

You are right, they don't work the same in the anime as they do in the games. In the games, the poke balls also break when you fail at capturing a pokemon. In the anime, it just goes back to the trainer.

The poke balls do shrink and expand when you press the button in the middle. This was a change introduced for the anime, because carrying a couple of poke balls at the same time would be very difficult. In the games, you can carry up to 99 of each type, which makes no sense outside of games because the character would not be able to carry more than a bunch of 3 inch orbs at a time. How many baseballs or tennis balls can you carry?

The poke balls can be stored big or small. The broken poke ball that Ash and Gary have was old and rusted from a river. It was likely thrown out or lost while small.

From one of the behind the scenes guides, concept art:

  • It may not be apparent from the sketch alone, but the small Pokeballs are worn on a belt with 6 slings, which is, more or less coincidentally, the same number of max. Pokemon allowed in your team during battle.
