What is the correct usage: bigger then or bigger than? When the context is that of a comparison, use "than"; in most other cases, especially when used in the context of time or the order in which events occur, the correct usage is "then". An easy way to remember is that "when" correlates with "then" (i.e. it relates to time). Another is "Thank God, who is bigger than me."
