Podcast Length
Calculator

The calculator simply sums the duration of each planned segment, intro, main discussion, ad breaks, outro, to give a total runtime, which is useful for scripting an episode to a target length before recording begins. It's straightforward addition, but the value comes from planning against a target.

Many platforms and audience habits favor certain episode lengths, commute-length episodes (20-40 minutes) perform well for casual listening, while in-depth interview shows commonly run 45-90 minutes, so planning segment lengths against a target keeps an episode from running long and losing listener attention or falling short of expected content depth.

Average conversational speech runs around 130-150 words per minute, so a planned script or talking-point outline can be roughly converted into expected speaking time by dividing word count by that rate, useful for estimating how long a scripted intro or ad read will actually take before recording it.

Live conversation naturally includes pauses, tangents, back-and-forth banter, and unplanned elaboration that a written outline doesn't account for, so unscripted podcast segments routinely run 20-50% longer than their planned outline time, which is worth padding for when targeting a specific total runtime.

Yes, post-production editing, removing filler words, long pauses, false starts, and tangents, can meaningfully tighten an episode, sometimes by 10-20% or more depending on how heavily edited the show's style is, so the raw recorded length and the final published length are often noticeably different numbers.
