Health to Size

Name: Health to Size
Author: Hexasan

Health to Size makes a player's body size follow their current health, with the size set by the server through commands and a data pack.

FabricForgeNeoForgeQuiltServer required, client optionalMIT License1.20.6 – 26.3

What it does

Size changes as health goes up or down, so a player who is hurt appears smaller and one at full health appears larger. The effect is driven by the generic.scale attribute that Minecraft added in snapshot 23w51a, which scales the player relative to their health. Servers can set the base Size Multiplier with a run trigger, or with a scoreboard value adjusted per player.

The change is applied per player by adding the dontSize tag, which lets server owners opt individual players out. Because the mod is delivered as a data pack for servers, the server carries the logic and clients only see the result. Builds are published for Fabric, Forge, NeoForge and Quilt, covering 1.20.6 – 26.3 across 18 release versions, under the MIT License, which is not open source.

Use cases

Survival servers

Server owners can use size as a visible sign of how hurt a player is during fights or hardcore runs.

Role-play events

Commands can switch the size multiplier for a whole group before an event and reset it afterward.

Who it’s for: Server owners and map makers who want a visual health effect without writing their own scripts. Single-player players are not the main audience, since the mod is set up through server commands and data.

How it compares

Full comparison

Player Size Changer is server-side and requires no client mod, with files for 1.21.4 – 26.3 under the MIT License and not open source. More Xp More Size is also server-required, client optional, and covers 1.20.5 – 26.3, but it scales size by experience instead of health. Random Size uses the same environment and version range, and its scale is chosen at random rather than tied to health.
