Match your audience’s commute or habit. 20–40 minutes works well for interview formats. Solo shows can be 10–20 minutes. Consistency of length matters more than the specific duration.
Use a plan like this one rather than a full script. Full scripts sound unnatural when read aloud. Key points and transitions are enough to keep you on track.
Consistency beats frequency. Weekly is ideal for most shows. Never go more than two weeks without an episode or your momentum will drop.
