That depends on the used browser and installed fonts, and probably operating system too. I'm using 150%, while the 24" screen is at arms length, and an additional full hand away. About 110 to 120cm, I guess? My defaults are still at 100%, though I go to 110 or 120 more and more, sometimes 133 to 150, but that tends to cause reflow. It's mostly 'mobile first' crap, for ppl used to read from the equivalent of a cashiers strip. shrug edit: With vertical tabs this looks very acceptable.
