I aim for the 25-35 minute range on my podcasts. This is primarily because any longer than that and I would go insane. I only have so much free time, and my girlfriend claims a fair chunk of it. I’ve already basically cut out video games entirely in the past six months to make room for the podcast (in fairness, I was already starting to tire of them, this is much more fulfilling. But I would love to play Mass Effect 3 and I haven’t even picked it up yet). It’s also a happy coincidence that A) the average commute is about this length, and B) most HPMoR chapters are about this length.
I’ve found that 4000-5000 words fits this nicely. More than that and the episode runs a bit long. Significantly more and I have to break it up into two parts.
Chapter 63 is over 14,500 words. I was hoping to do it in two parts, but I was defeated. Therefore 63 will be my first three-part chapter. I wish it weren’t so, but I am a mere mortal and I have to hold down a full-time job too.
