[Dr. Drib]

Issybird may wish to expand upon this.

The scansion of a line of poetry (the metrical rhythm of the line) can sometimes be compromised due to the width of the screen size on an individual ereader.

To put it another way: A line of poetry may have to be shortened due to the screen realities of the individual ebook reader that one owns, which means that a 'long' line may have to drop to the next line (when no line break occurs in the original poem), which can impact upon the look as well as the reading and appearance of the original line. This can compromise the beauty and the meaning of some poems.

Some of these issues can be 'overcome' if one makes the print tiny.
