CharacterSize
CharacterSize lets a player grow or shrink the character with keybinds, and the change carries over to speed, reach and block breaking.
What it does
Two keys set the character size on Fabric: G raises it, up to a scale of 3, and H lowers it, down to 0.5. The scale changes in real time, and the player model, hitbox and eye height update with it while the game runs.
Larger sizes come with a trade-off built into the scaling. A bigger character moves faster and has extended reach for attacking blocks and entities, which suits combat and building. When the character is big enough, breaking one block also removes the neighboring blocks in a square patch around it, so a single swing clears ground quicker.
The mod is for Fabric only and runs on client and server, so the server and every player need it. It is published for 1.21 – 26.1 across 13 release versions, with 1.0.0 for 26.1 as the latest file. It was first published on 2026-03-22 and last updated on 2026-03-29. The code is public, but all rights are reserved and the mod is not open source.
Key features
Dynamic scaling
Press G to grow up to 3 times normal size, or H to shrink down to 0.5, with changes applied in real time.
Enhanced mobility and reach
Larger characters move faster and gain longer attack and block interaction ranges, which helps in combat and building.
Area breaking
At large enough sizes, breaking one block also breaks the adjacent blocks in a square area, clearing terrain quicker.
Smooth ability scaling
Speed, reach and breaking abilities scale with the chosen size, giving the player control over their presence in the world.

Use cases
Building at scale
A large character reaches farther and moves faster, so a build can be placed or cleared without walking back and forth.
Quick terrain clearing
Area breaking removes a square of blocks in one swing, which speeds up clearing a site or a cave wall.
Who it’s for: Players on Fabric who want a character that changes size on the fly, and server owners who want a size-based mechanic running for every player.
