The situation is very common on the Web now. My 17" monitor is from NEC years ago, is razor sharp and rock solid, and I see no great reason to take time out to change from it. Besides, as another comment in this thread noted, laptops also have relatively small screens! So do tablets and phones!

I know nothing about using Google's blogspot.

For the Web site I'm building, all screens are just 800 pixels wide, and all my fonts are nice and large. So, on a big screen, could have a 'pile' of dozens of such windows each offset a little, and on a small screen could still see the full width easily without using horizontal scroll bars.

How'd I do that? I'm a beginner at HTML but just stuffed in 800 px some places, and got 800 pixels. If in a browser I shrink a window to less than 800 pixels, then I get horizontal scroll bars.

Broadly it's easy to assume that there it's reasonable to use lots of space vertically and let the user do a vertical scroll but try to minimize space used horizontally so that a user doesn't have to do a horizontal scroll just to read the text.

In some cases, I just highlight the text, copy it to the clipboard, pull it into my favorite editor, and flow the text to, say, 60 characters a line.

My view is, in reading, 40 characters per line has some advantages in eye movement in reading, 60 characters per line is plenty, 72 is almost too many, 80 is about the upper limit, and over 100 is too often a problem and, really, for easy eye movement in reading, too much.

Heck, even when newspapers had sheet sizes big enough to cover a table top, they still kept way down the number of characters per line.

But I can't tell the world how to design Web pages. If some people want, say, 300 characters per line and 20 characters per inch on the screen horizontally, then so be it.
