GoldSrc Dimensions

Stub

This article or section is a stub. You can help by expanding it.

The standard measurement in GoldSrc is a unit (normally referred to as a Hammer Unit or Quake Unit) which are loosely described to be equal to 1 imperial  inch (2.54 centimeters) or 0.75 inches (1.905 cm.). These are loose approximations, however, and dimensions may vary depending upon what "feels right" in-game, rather than a direct conversion of the real-life dimensions.

Map Size

8192x8192 is the max size for a GoldSrc map in most games. This is 4096 units from the map's origin.

World geometry can be placed outside of these bounds, but it will be clipped off unless the game code and delta.lst accounts for it (such as in Sven Co-op). ^[Clarify]
