What is a bigger katana?

Excuse me, could you please clarify what you mean by "a bigger katana"? Typically, a katana is a traditional Japanese sword known for its distinctive curved blade. It's not a term that is typically associated with size variations in the same way that, say, a "large shirt" or "small car" would be. Are you perhaps referring to a katana that is longer or wider than the standard size? Or perhaps you're asking about a different type of sword that is similar to a katana but larger in some way? Could you please provide more context or specify what you mean by "a bigger katana"?
