Around 30 chapters if I'm binge-reading a gripping series on a free day! For full titles, I usually stick to just 1 or 2 at a time so I can actually absorb the story and art properly without burning out.
I read like 5-10 chapters a day max. I like to savor it, look at the art, reread the romantic scenes 3 times. I'm a slow reader but obsessed reader lol
