Player Size Changer

Java data pack listed for Minecraft 1.21–26.x. File opened and checked on 15 Oct 2026; downloads from the MC Java Mods app on Android.

This is a datapack with which you can change your size between 5 different sizes. Each one of them also changes other attributes like health or range…

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.21.9–26.3 · Data pack⬇ Download for 1.21.9–26.3 · Fabric⬇ Download for 1.21.9–26.3 · Forge⬇ Download for 1.21.9–26.3 · NeoForge⬇ Download for 1.21.9–26.3 · Quilt
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This is a datapack with which you can change you size in minecraft. Accordingly to your size other attributes like health, range, jump hight and some more will change too. For example, if you are small you can move better, but you have less life and can jump lower. On the other hand, if you are big you have a lot of lives and can jump higher, but you can no longer fit everywhere!

There are currently 5 different sizes:

To change you size, you have 3 options:

  1. [Recommended] You can change your size by opening the change size menu in the pause screen of the game: Picture of the minecraft pause screen with the button "change size" marked in red. Press on "Change Size" (here marked in red) and the following menu will open where you'll be able to change your own size: Picture showing the change your size menu with five differrent options to change the players size.

  2. If clicking the change size button opens a menu from a mod (like Mod Menu), you'll have to use the following command to manually open the menu:

/dialog show @s size:change-size
  1. If you are using an earlier version of minecraft or of the datapack/mod, your only option is to use the following commands to change your size:
/trigger 0.2x

/trigger 0.5x

/trigger 1x
