How this is calculated

In metric, 30.2 cm wide by 18.9 cm tall, roughly 570 cm². A 14-inch 16:9 screen would be 12.2 inches wide but only 6.9 inches tall; the 16:10 panel gives you about 8% more vertical space. That half-inch difference is the equivalent of roughly three extra lines of text in a code editor at standard font sizes, which adds up over a workday.

Verdict

14 inches at 16:10 is the ideal laptop screen format for anyone who reads or writes for a living. It balances portability (fits in every backpack sleeve) with enough vertical space to feel less cramped than a 13-inch. If you're choosing between 13-inch and 14-inch, go 14; the chassis size difference is negligible and the screen real estate gain is real.
