Quick answer
At a natural storytelling pace of about 155 words per minute, a 30-second Short fits roughly 78 words and a 60-second Short about 155 words. Calm narration (around 130 wpm) fits fewer words; fast explainer delivery (around 175 wpm) fits more.

How many words is a 60-second Short?

Roughly 130 to 175 words, depending on delivery. Most faceless storytelling channels land around 150 to 160 words for a minute, which leaves room for a beat after the hook and a pause before the payoff.

YouTube Shorts can now run up to three minutes, but shorter videos are easier to watch to the end, and completion is one of the strongest signals for short-form.

Why count scenes as well as words

Faceless videos hold attention by changing the picture often. A new visual every three to five seconds is a common rhythm, so a 60-second script needs about 15 scenes. The calculator estimates this for you.

FAQ

How many words per minute is a normal speaking pace?

Conversational English is usually 140 to 160 words per minute. Narrators slow down for drama or bedtime content and speed up for fact-heavy explainers.

How long should a YouTube Short be?

Shorts can be up to three minutes long. For new channels, 30 to 60 seconds is a safer target because it is easier to keep viewers to the end.
