How Long is My Voice Over Script?

Clients often ask, “how long should a voice over script be?” Check out the Script Timer Voice Over Calculator above! My experience in post-production and as a voice talent taught me that for long-form narrations one should figure around 140 words per minute of script. However, This number can go as low as 130 wpm if you have a lot of time for graphics and transitions in your video. Or, it can go as high as 160-170 wpm if you want the script to go very fast. I wouldn’t recommend such a pace for more than five minutes, or the audience will face “listening fatigue“. On the other hand, Broadcast commercials are lightning-quick, and 180 wpm and higher are often typical, especially for hard-sell spots. Enter your script word count and desired pace of 140, 160, or 180 words-per-minute in the calculator above.

Here’s a handy script timer or word-per-minute timer spreadsheet for voice over scripts. Choose the pace or style of narration you need in the left column, and then find how that translates into a real-world timed count in the right columns.

Remember, you can always manually enter your script length into a calculator by entering the word-length of your script and then divide by:

130 for a slow pace with extra pauses

140 for a normal narration pace

150 or 160 for an uptempo conversational pace

170 or 180 (or higher) for a fast, commercial pace.

Your answer will be how many minutes your voice over will be. This is a crucial calculation to make in pre-production to avoid over and under-estimations. You can’t fix that in the mix! Even doing a ‘scratch track’ ahead of time usually comes off rushed and without the correct pacing. Always keep the Script Timer Voice Over Calculator guidelines in mind.

All the very best,
