I’m not sure which “black box” you mean, because Roblox uses that phrase for different things. In most Roblox skybox lore, the Blackbox is a fan-made layer and there isn’t a confirmed “stud” distance where it ends; the available sources describe it as part of a layered theory rather than a measured, official boundary.

If you mean the skybox lore

  • There’s no official Roblox measurement for where the Blackbox ends in studs.
  • The idea comes from community theory pages and videos, not Roblox documentation.
  • So any stud value you see is usually a guess or a creator’s estimate, not a verified constant.

If you mean the Roblox Studio black box

  • That usually refers to a UI or rendering issue, a flight recorder, or an object/build artifact, depending on context.
  • In those cases, “ends in studs” doesn’t really apply.

Most likely answer

If you’re asking about the Roblox skybox myth, the safest answer is: it doesn’t have a known official endpoint in studs. That makes it more of a lore question than a geometry question.

If you want, I can also help estimate it from a specific video or game map.
