What is the optimal size for a class file?

Question

I know that there is no single “ideal” class file size, but still ...

Is there any data (e.g. research, not opinion) about what is the optimal size for the class file?

Answer 1

I would say that the optimal size will be sufficient for the class to do its job.

Answer 2

Opinion: The smallest possible size that does this work, while maintaining readability, but increasing brevity.

There is some work in academia on this topic to try to be more formal.
