When planning a narration, words per minute voice over<\/strong> is a useful starting point for estimating how long a script may run. It is not a fixed rule, though. A 900-word explainer can take very different amounts of time depending on the speaker, audience, subject matter, pauses, pronunciation, and performance direction.<\/p>\n\n\n\n

The most reliable workflow is simple: use a preliminary words-per-minute estimate to scope the script, create a draft read, then time the actual audio. This approach helps you set realistic expectations without forcing every voiceover into one pace.<\/p>\n\n\n\n

The basic voiceover timing formula<\/h2>\n\n\n\n

Use this formula to estimate a script’s running time:<\/p>\n\n\n\n

Estimated duration in minutes = total script words \u00f7 words per minute<\/p>\n\n\n\n

For example, a 750-word script read at 150 words per minute (WPM) would have an estimated duration of five minutes:<\/p>\n\n\n\n

750 words \u00f7 150 WPM = 5 minutes<\/p>\n\n\n\n

To estimate in seconds instead, multiply the minutes by 60:<\/p>\n\n\n\n

Estimated duration in seconds = (total script words \u00f7 WPM) \u00d7 60<\/p>\n\n\n\n

This arithmetic is useful for rough planning, such as deciding whether a script fits a 30-second ad slot, a two-minute product video, or a longer training module. It should not replace a timed read when the runtime matters.<\/p>\n\n\n\n

The table below shows transparent timing scenarios, not universal voiceover standards. It assumes continuous spoken words and does not automatically account for long pauses, music breaks, demonstrations, or retakes.<\/p>\n\n\n\n

For a quick estimate, divide your word count by a few plausible pacing scenarios instead of choosing one number too early. That gives you a practical duration range to discuss with stakeholders.<\/p>\n\n\n\n

For instance, a 600-word script may be approximately:<\/p>\n\n\n\n
