My Navigation
The Area
My favorit size for the navigation area is between 80px - 100px. Not too big but still have enough room for playing with font size variations and whitespace.
The Text
For text, my favorite size is 14px for lowercase and 12px for uppercase. In my opinion, text inside navigation no need to big, as long it's easy to read. Big text on navigation area can cause distraction and take some space
Tips
No need to super big
Main function of the navigation is to help user to see menus they can access. Using proper size for the navigation area as long the link or text inside it easy enough to read and have some whitespace is perfect for me.

Using super big navigation area, with so many whitespace and big text or link inside it is a big no for me, since it would be takeaway some space. Better to allocate that space for more important things or content.
