Quick answer
To make reading PDFs on a tablet more comfortable, fix text size or zoom first, then page width, brightness, and reading movement.
Large pages can still need zoom or crop when margins are wide.
Start with size
Use crop or fit-to-width before extreme zoom.
If lines become too short, reduce margins before increasing size again.
Use the screen width well
Very wide lines can be hard to track on a large tablet. Very narrow text can create too many line breaks on a phone.
Use moderate margins that fit the screen.
Choose page or scroll
Try both on the same chapter. Keep the one that makes it easiest to follow the text and return to your place.
Night reading
Lower screen brightness to match the room and keep strong enough text contrast.
A dark page is optional; the important part is clear text.
