Quick answer

In Roblox, you can’t globally “reroll your height” across all games —height is either fixed by your avatar settings or controlled separately by each game. That said, some specific games do offer in‑game ways to reroll or change your height , usually via NPCs, shops, or gamepasses.

Below is what’s known from public guides, wikis, and forum discussions as of 2024–2026.

Where height rerolls actually exist

1. RPG / anime-style games with NPC rerolls

Certain anime/RP-style Roblox games include dedicated NPCs or mechanics to reroll character traits , and height can be one of them.

  • In at least one popular anime-style game (often discussed in guides and videos), there’s a “height reroll” NPC located near a dojo/training area.
    • You interact with the NPC, confirm, and pay in-game currency (e.g., around 20k cash in that specific title) to reroll your height.
* These games often bundle height rerolls with other customization options like **style resets, psyche resets, and card resets** , all handled by different NPCs in the same map.

If you’re thinking of a specific game you saw on TikTok/YouTube where someone “rerolled height,” it’s very likely one of these anime fighting/RP games with a dedicated reroll NPC.

2. Games with gamepasses or tokens for height/weight rerolls

Some Roblox experiences sell gamepasses or consumable tokens that let you reroll physical traits:

  • Example from a game wiki:
    • “Reroll token” – bought with Robux, used to reroll your height or weight.
* **“Reset token”** – also purchasable, used to **reset your stats** (which can indirectly affect appearance).

These are per-game ; buying a reroll token in Game A does nothing in Game B.

3. “Height Simulator” and similar growth games

Games like Height Simulator focus entirely on changing your size:

  • You grow taller over time by eating foods, completing tasks, and interacting with the world.
  • While not a “reroll” in the random-stat sense, you can effectively reset your progress by leaving and rejoining or using in-game mechanics if the developer provides them, then start growing again from a new baseline.

These are more “progression” games than character-creation reroll games, but they’re built around manipulating height.

Where you cannot reroll height

Most standard Roblox games

In the majority of Roblox experiences:

  • Your height is determined by your avatar’s body scaling in the Roblox Avatar Editor or by the game forcing a specific avatar type (R6, R15, Rthro).
  • If a game forces R15/Rthro or locks scaling , you cannot change your height in that session , even if your main avatar is differently sized.
  • There is no global “reroll height” button that works across all games.

As one Reddit thread put it:

“Similar to how certain games mandate the use of R6, there are also games that require R15 or Rthro. Unfortunately, there’s nothing you can do.”

So if you join a game and suddenly look “too tall” or “too short,” it’s usually because that game overrides or ignores your custom scaling.

How to change height outside of specific games

If your goal is just to be a different height in general , not in one particular game, you can adjust your avatar:

  • Go to roblox.com → Avatar → Body.
  • Use the height slider in the Body section to make your avatar shorter or taller.
  • This affects any game that respects your avatar scaling , but again, many games will override it.

Developers can also use Roblox Studio to set custom scaling or HumanoidDescription properties, but that’s for game creators, not players.

Practical checklist: “Can I reroll my height in this game?”

When you’re in a specific Roblox game and wondering if height reroll is possible:

  • Look for:
    • An NPC labeled “Height Reroll,” “Reroll,” or similar.
    • A shop/menu option mentioning “height,” “body,” “appearance reroll,” or “tokens.”
    • A gamepass in the game’s store that mentions height/weight reroll.
  • Check:
    • The game’s description or info page on Roblox for mentions of “reroll,” “appearance,” or “stats reset.”
    • The game’s Discord, wiki, or YouTube tutorials —many anime/RP games have guides showing exactly where the reroll NPCs are.

If you can’t find any of these, the game likely does not support height rerolls and uses either your global avatar scaling or a fixed size.

TL;DR

  • There is no universal “reroll height” feature across Roblox.
  • Some specific games do allow it:
    • Via in-game NPCs that reroll height for cash or coins.
* Via **gamepasses/tokens** that let you reroll height/weight.

* Via **height-focused games** like Height Simulator where growth is the core mechanic.
  • In most games, your height is controlled by avatar settings or forced by the game , and you cannot reroll it there.

If you tell me the exact game name you’re playing, I can narrow down whether that specific title has a known height-reroll mechanic and where to find it. Information gathered from public forums or data available on the internet and portrayed here.
