First, decide if you want to read it digitally or in print. If digital, get a decent-sized screen. If print, find a comfortable chair. Also, take breaks to avoid eye fatigue.
Websites like Viz Media and Webtoons are also worth checking out. Viz Media has licensed manga, and Webtoons has some unique and interesting manga-style comics. Just make sure to follow the site's rules and terms of use.
The common way is to start from the right and progress to the left. But some special formats or series might have their own unique reading directions. So, always keep an eye out for any specific instructions given within the manga itself.
To read manga properly, make sure you have good lighting and a comfortable position. Focus on the characters' expressions and the story development. And don't rush through it; savor each page.
Typically, you read a manga by starting on the right page and moving top to bottom within each panel. It's pretty straightforward. But keep an eye out for any unique indications given within the manga itself.
Personally, I think getting the official e - book version is a great way. It's convenient as you can carry it around on your device and read it whenever you have time. The formatting is usually good and it supports the author.
