How big is a token?

I'm really curious about the concept of 'token' in the realm of cryptocurrency. Could you possibly enlighten me as to how big a token actually is? Is it a measurable quantity, like a certain number of coins or units? Or is it more abstract, referring to the overall value or significance it holds within the crypto ecosystem? I've heard people talking about tokens in different contexts, and I'm trying to get a grasp of what they really mean when they say 'token'." "Moreover, how does the size or magnitude of a token impact its functionality or utility within a blockchain network? Are larger tokens more powerful or influential? Or is it all about the specific use cases and applications that a token is designed for? I'm eager to understand the nuances and intricacies surrounding this topic, and I believe you're the perfect person to help me unlock these mysteries.
