Quick answer
For page margins, change the smallest thing that affects readability first. Test it before touching color, margins, or motion.
Margins control how close text sits to the screen edge.
First change to try
Reduce very large margins on a small screen. Keep enough space that the text does not feel pressed against the edge.
Use a real chapter, not only a settings preview.
Second change to try
If the first change is not enough, adjust line spacing or margins next.
Avoid adding several strong visual changes at once.
How to compare
Use the same page before and after the change. Read for five minutes, not five seconds.
Keep the option that reduces re-reading and line loss.
When to stop
Stop adjusting when the page is comfortable. More customization is not automatically better.
A stable setup is often easier to read with than a constantly changing one.
