Pehkui Mod (1.19.2, 1.18.18) allows mod developers to change the size of entities.

This API can be used by other mods to alter the entity’s size and the time it takes to change their size. Entities will be restored to their original size if this mod is removed. It will not restore their original size.


  • Change the size of entities through modifying scale data.
  • Affect other properties of an entity that are considered as dependant on the size (e.g. movement speed, explosion size, reach distance).
  • Have the scalable properties of an entity be affected by other scale data types or by external data through scale modifiers.

If you have no mods that add ways to rescale entities, you can modify and view the scale and scaling delay of an entity in-game using the /scale command:

  • /scale set [entity]
  • /scale set [entity]
  • /scale <add|subtract|multiply|divide> [entity]
  • /scale <add|subtract|multiply|divide> [entity]
  • /scale get [entity]
  • /scale get [entity]
  • /scale compute [entity]
  • /scale delay set [entity]
  • /scale delay set [entity]
  • /scale delay get [entity]
  • /scale delay get [entity]
  • /scale reset [entity]
  • /scale reset [entity]
  • /scale nbt get [entity]

If you want your player’s scale to persist after you respawn, there’s a /scale subcommand for that as well:

  • /scale persist set <true|false> [entity]
  • /scale persist set <true|false> [entity]
  • /scale persist get [entity]
  • /scale persist reset [entity]
  • /scale persist reset [entity]

The following scale types are added by default:

  • pehkui:base: Generic scale type for easily affecting other scales
  • pehkui:width: Modifies width/length/depth (affected by pehkui:base)
  • pehkui:height: Modifies height (affected by pehkui:base)
  • pehkui:hitbox_width: Modifies width/length/depth of an entity’s hitbox (affected by pehkui:width)
  • pehkui:hitbox_height: Modifies height of an entity’s hitbox (affected by pehkui:height)
  • pehkui:eye_height: Modifies height of an entity’s eye position (affected by pehkui:height)
  • pehkui:model_width: Modifies width/length/depth of an entity’s model (affected by pehkui:width)
  • pehkui:model_height: Modifies height of an entity’s model (affected by pehkui:height)
  • pehkui:third_person: Modifies player third person camera distance (affected by pehkui:height)
