How long do you typically read? Do you go by a set time or by chapters?

I read comics and I go by chapters. The length of time I read depends on what happens in the chapters ,'cause I'm usually very excited to read what happens next.

depends, at the moment i do it by time, i.am struggling to read so time motivates me better but i like to finish things so i will push to get to the end of a chapter

I like to read at least one chapter a day. The chapters are roughly 20 pages long. Maybe I have OCD but I hate leaving in the middle of a chapter.
