Does size of a theme’s functions.php file matter?

I guess it doesn’t really matter, but I think it’s better to keep it as short as possible.

Before, I used to put all of my logic in my functions.php file.

But it was quick big at the end (like 2000 lines of code, sometimes more).

Now, I prefer generate a sample theme thanks to this : https://underscores.me/

And for my plugin, that https://wppb.me/

Thanks to this, functions that I usually use in my websites are all in my plugin, so my theme is lighter

Think to seperate all your content logic in files/folder (inc/entities for post_type, inc/cron for your cron… it depends on you !)
