You can change your height in Seishun Roblox by editing your avatar’s Build/Scale settings, then dragging the height slider up or down. The usual path is: Avatar → Customize → Head & Body → Build or Scale, then adjust Height.

Quick Scoop

  • Open Roblox and go to your Avatar editor.
  • Tap or click Customize.
  • Go to Head & Body, then find Build or Scale.
  • Move the Height slider up to be taller or down to be shorter.
  • Changes usually apply right away.

On mobile

On mobile, the steps are basically the same: open Roblox, tap Avatar , choose Customize , then go to Head & Body and find Build or Scale. From there, drag the height control to your preferred look.

If it does not work

If the height slider is missing, your avatar may be set to a body type that does not support scaling the same way, or the game you are in may override your avatar’s look. Some experiences also use their own character settings, so your height may look different in-game than in the editor.

Simple example

If you want a taller Seishun character, go into the avatar editor and push the height slider higher; if you want a smaller look, pull it lower. That is the main control most guides point to for Roblox avatar height changes.

TL;DR: Go to Avatar → Customize → Head & Body → Build/Scale, then adjust the Height slider.
