Great job using the format of your text to reflect your message. I did find that I preferred the shorter line length, even though I believe that I read the longer lines faster.
Research shows that 100 characters per line is
the optimal length for reading on-screen; this allows for the fastest reading speeds because your eyes don't have to keep jumping from line to line as much, interrupting the flow of your reading.
Most people actually prefer a short or medium line length of 45 to 72 characters per line. This is because people think it is easier to read shorter columns of text and also believe that they can read it faster. The truth is that people can read a single wide column faster than multiple columns.
If you are designing something where reading speed is less of an issue, use a shorter line length of 45 to 72 characters per line. Multi page documents work well with 45 characters per line so that the text takes up more space.
