Big Head Mode
by Kim-Lan
Big Head Mode is a Fabric client mod that enlarges player heads by default to twice their normal size, and its scale can be changed in a config file.
What it does
Only the player who installs it sees the change: a scale setting is applied to player heads on the client, and the server and other players keep normal heads. Because the effect is cosmetic and client-side, it does not alter gameplay for anyone else. The default scale is 2x, and the head size can be raised or lowered within a permitted range by editing the big-head-mode.json5 file.
The mod is a nod to the Big Head Mode of the 2023 April Fools update, which enlarged heads in the same way. It fits players who want a silly look on singleplayer worlds or on servers that allow client mods. Setup needs Fabric API and oωo (owo-lib); Mod Menu is optional and gives a settings screen for the head scale. Big Head Mode is released under All rights reserved and is not open source, though its source code and issue tracker are public. Files are published for Fabric for 26.1 and 26.2, with the latest build 1.0.0+26.2 dated 2026-09-05.

Use cases
Silly singleplayer play
A player running a private world can switch on oversized heads for a lighthearted session without any server setup.
Community joke servers
Players on a server that allows client mods can use the mod to add comic character to the game, since no one else is affected.
Who it’s for: Players who want a cosmetic, comedic change to how player heads look, and players who remember the April Fools feature it is modeled on.
How it compares
Keep Head Names is open source under the MIT License and runs on Fabric, Forge and NeoForge for 1.16 – 26.3, with the server required and the client optional. So Big: 250% is a Fabric mod for 1.20 – 26.3 that requires both the client and the server, and it is not open source under All rights reserved. Big Head Mode is client-side only and not open source.
