I usually can read something with 60-50 chapters in half a day or so. My friends take longer. Usually I don't have anything to do after I come home from college and do my assignments, so I just read some and watch K-drama with my boyfriend.
If you're the talkin about novels then if the story really captures me, I can finish it within one day. If not, then I can finish it in 4 days. If you're talking about webtoons, then I can finish it in one day if it's totally completed. reply
