Uncle Bob (writer of the Clean Code book) argues that functions should be small (3-10 lines long, and not longer). He brings up 2 points as far as I remember.

1 - functions are(should be) well named so anyone later on will have better understanding of the intent of the writer of the code.

2 - bugs have a harder time to hide in 5 lines of code than 30 or 300 lines of function code.

If you did not read it I recommend it or the video series based on the book.

I worked on only one code base where we more or less held ourselfs to this and the class length limit (classes really should not be more than 2-300 lines long) and it turned out pretty well.
