      I hear people say that shorter lines = better, but when I check the primary sources, I find that they have no primary source or that longer lines are arguably better. Is there an actual study on this that studies reading "long" lines that finds that they're obviously worse?pic.twitter.com/zxWSJucVPT

      My understanding is longer lines need bigger font and line height. Line length needs to harmonize with the context. I think its a question of style and aesthetics mainly. Source + game:https://betterwebtype.com/triangle/

      I've also heard this (for other parameters as well), but the vast majority of line length studies show a result where they vary line length without changing other parameters. A typographer told me this was proven in some book. I read the book. It was not proven in the book.

      I looked at the page you cited, it assumes the result and doesn't provide evidence? In the first example I got, I chose the one that I would prefer to read, and that's "wrong". The page trains you to set up parameters as the page author prefers, but why are those preferred?

      I think of it like how much salt to add to a dish. If you learn what a good chef thinks is the right amount it gives a reference point for your own experiments.

      I agree that this is a matter of taste and preferences will vary between individuals, but I don't think it's heretical to run taste tests on literal taste for things like amount of salt in a recipe, why not for this as well?

      I agree we should try, but I think its one of those problems where a study could conclude whats too long, and whats too short, but leave the middle open for interpretation. Individual preferences is noisier than the accuracy we need to be useful. I'd be happy to see otherwise.

      Yeah. Relatedly, I would prefer to see the distribution and not just a mean or median plus std dev. or quartiles, but that's rare (though it's becoming more common for many other kinds of studies). I think this is esp. important when underlying preferences are expected to vary.

      Something else that's difficult to study that I'd be curious about is how cultural this is. When people first started limiting line widths on the web (often assuming 640x480 or 800x600 even though many people had larger displays), most people I knew thought this looked terrible.

      But now the opposite is true, if you remove width restrictions, most people think that's terrible. How much of this is people just liking what they're used to and how much is inherent? Unlike the line length question in isolation, I can't think of a good way to study this.

          Sure, but unlimited line length on 4K monitor means http://danluu.com  makes me split my screen. The content is good enough for me to still read though. I think it would be better with padding + line width, even if it was large like 140 characters.

          I think something that would track eye movement when reading. Too long means eyes have to go back and forth. To short there is too little field of vision for efficient information transfer

          I also think rhythm would be another good avenue. How long does it take to read through a passage? What's the recollection rate? This is for music, but I it has an approach for finding the slowest music — 33 BPMhttps://youtu.be/afhSDK5DJqA?t=75 …

          So I'd start with one line should take at most 1.8 seconds for the intended audience to have a maximum score on a reading * retention metric (time vs Shannon entropy?). Then experiment with different line lengths to see if there is a trend.
