Carl the NPC’s exact height doesn’t appear to be officially stated, but in Roblox terms he’s generally treated like a standard classic avatar, which is about 5 studs tall.

Quick Scoop

  • No reliable source I found gives a canon real-world height for Carl the NPC specifically.
  • The closest useful reference is the classic Roblox avatar scale, which is about 5 studs tall.
  • So the safest answer is: roughly Roblox-avatar height, not a fixed official measurement.

What that means

If you’re asking for a meme-style estimate, Carl is basically “normal Roblox character tall,” not unusually short or giant.

If you want, I can also estimate that in feet or centimeters using the common stud-to-real-world conversions people use for Roblox avatars.
