One of the basic questions all the time is what kind of screen size should page fit-in without horizontal scroll. Probably the best answer could be found by testing one good page. Which one should be the best? How about that one which is Cascade Style Sheets (CSS) guide for all of us? So:
Small note: ‘browser’ in my understanding, is the program (one of above) with maximized usable / visible page-content surface.
* Any other (view) size which is larger then above, make document unreadable (more correct: vertical nav-bar became unaccessible / scrollable content — ok). The same note for each item bellow.
This small table could be probably useful for some developers... to take in the mind when doing their own works.
Personally, I think that everything is ok there; page is of that kind which we can describe as ‘an ideal page’ with nice rich style.
