One of the oldest coding exercise is to proceed business width 80, too many of us follow it blindly but convey you lot always idea why nosotros convey this exercise inward commencement place? I believe it was to brand your code to a greater extent than readable inward the historic menses of pocket-size monitors thence that whole content tin terminate tally inward the screen, or it powerfulness convey originated from the historic menses of punch card, which was used to live eighty column wide. This sounds reasonable when nosotros intend almost those sometime days but do you lot intend this dominion makes feel inward 2018? We are straightaway living inward the historic menses where most of the developers convey got large monitors, which tin terminate exhibit up-to 180 characters, doesn't this is wastage of precious monitor space? It also makes your code unnecessary long, thence it genuinely is.
I commencement come upwardly to know almost business wrapping at 80, spell reading Oracle Code Conventions for the Java Programming Language, which was lastly revised at Apr 20, 1999, which nether indentation says

If I understood correctly (I may live wrong), 1 finish of this dominion is consistency. I used to intend that eighty was silly, but beingness able to larn through source code written yesteryear a dozen dissimilar teams over lastly seven years too non needing to re-size my window is a genuinely overnice thing. Consistent column width helps amongst the measuring of reading code.
Since I mostly worked amongst large monitors, similar LG 32MP58HQ-P 32-Inch IPS Monitor with Screen Split, I also realize that nosotros are wasting lots of precious space. The consistent column width of eighty is but likewise little. I personally purpose 120 unless the projection I function already finalized a column width, inward that case, I larn for consistency.
One to a greater extent than argue people give for nevertheless using a column amongst of eighty is that present they are working amongst multiple files at once. For example, if you lot purpose touchstone column width you lot tin terminate tally a pair of files across a argue too tin terminate compare them business yesteryear line, which I believe is a existent benefit.
You tin terminate fifty-fifty do a three-way merge inspection on 1 hide without scrolling sideways. By the way, this should non live done at terms of excessive wrapping. I empathise that consistent columns larn inward easier to scan too read through text but it doesn't affair whether it's eighty or 120.
On a closing note, I would tell that consistency is overnice too you lot must larn for it but eighty or fifty-fifty 100 is likewise short. Many developers could likely alive amongst 120 or fifty-fifty 150 though. Our modern widescreen high Definition LCD monitors tin terminate easily possess got more.
It is much to a greater extent than readable than the excessive wrapping because I personally uncovering it much harder to read a wrapped business than exactly seeing the whole thing inward 1 line. Of course, this is exactly preference too others volition experience different.

4.1 Line Length
Avoid lines longer than eighty characters, since they're non handled good yesteryear many terminals too tools.
Note: Examples for purpose inward documentation should convey a shorter business length-generally no to a greater extent than than seventy characters.
