The original default walkspeed in Roblox is 16 studs per second, and that’s the baseline most games start from unless they change it.

For Heroes Battlegrounds , I couldn’t verify a separate official original walkspeed value from the sources I found, so the safest answer is that it likely uses the Roblox default unless the game or a specific mode changes it.

Quick note

If you mean a specific character, sprint state, or a modified server setting, that value can be different from the default.

TL;DR

  • Roblox default walkspeed: 16 studs/second.
  • No confirmed separate official Heroes Battlegrounds baseline found in the available sources.
