How to use this tool
- Count the words that will actually be spoken; exclude headings, visual directions, pronunciation notes and pickup logs.
- Enter a positive whole word count and choose the closest narration pace. WPM means words per minute.
- Record a representative read. Allow for longer pauses and visual holds, and replace the estimate with the measured timing when available.
Word-count and pace examples
- 140 words at 140 WPM: 140 ÷ 140 = 1 minute of estimated speech.
- 330 words at 110 WPM: 330 ÷ 110 = 3 minutes. A separate 20-second visual demonstration would make the planned total 3 minutes 20 seconds.
- 700 words at 140 WPM: 700 ÷ 140 = 5 minutes. At 170 WPM, the same text is about 4 minutes 7 seconds.
What the estimate excludes
The calculator does not read your delivery notes or measure pauses. Longer silences, visual-only demonstrations, music breaks, retakes and recording setup are not added automatically. If a pace measured from your own read already includes ordinary breathing and pauses, do not add those same gaps twice.
For example, a 700-word draft at 140 WPM plus a separate 15-second visual hold gives a planning total of 5 minutes 15 seconds. A real read may still differ. Time the assembled narration and visuals before fixing the final edit length.
Prepare a script you can record
Use the voiceover script format template to mark pauses, pronunciation and pickups. Use the two-column video script template when narration must line up with specific shots or silent holds.
Plan the delivery and visuals
Read the voiceover pacing guide for practical advice on emphasis, pauses, and clarity. If the narration drives your edit, use the B-roll planning guide to match useful visuals to each section.
Frequently asked questions
How long is a 1,000-word voiceover?
At 140 words per minute, 1,000 words is approximately 7 minutes and 9 seconds. Longer pauses and visual holds can extend the finished runtime.
Does the estimate include retakes?
No. Retakes and setup add time to the recording session. A selected retake normally replaces an original line in the edit rather than adding to the finished voiceover.
Why does my recording differ from the estimate?
Your actual pace varies with breathing, emphasis, pronunciation and familiarity. The selected pace is a planning assumption, so a recorded read gives a better measurement.
Is faster narration better for short-form content?
Not always. Faster delivery can add energy, but clarity and comprehension should come first.
