Line lengths

Please would it be possible to print messages in shorter line lengths. The view of solid chunks of print is rather intimidating to a person of my advanced age and I give up before the end of a line.
Even if this is not possible a few paragraphs might help.

If you make your window smaller, the line length will be shorter.

I find that if I make my font larger, the lines wrap more frequently. So a line, while still the same length, is easier to read because my strained eyes don't have to travel so far to the right, then back to the left again.

I'm on a windows laptop. I can make the font on my screen larger by pressing at the same time control (key)+

And the reverse will make it smaller control (key)-

Paragraphs depend on the person writing the message. Not much LT can do about that.

Thank you for your help.
