Voiceover Duration Calculator
Estimate narration length from script word count and speaking speed.
Estimate how long a narration, YouTube voiceover, podcast intro, presentation, or ad script may take to read aloud.
Speaking speed matters
A calm explanatory voice may be slower than energetic short-form narration. The editable words-per-minute field lets you model different delivery styles.
Pauses add time
Music beats, dramatic pauses, breaths, laughter, scene changes, and emphasis can make the final recording longer than a pure word-count estimate.
Use it before recording
If a video has a fixed duration, this tool helps you trim or expand the script before generating or recording the voice.
Frequently asked questions
What WPM should I use?There is no single correct speed. Record a short sample of your own voice and calculate its approximate WPM for the best estimate.
Does punctuation affect the calculation?Not directly; pauses from punctuation are reflected only if you lower the WPM assumption.
