Script to Runtime
Translate a script's word count into its spoken runtime.
About Script to Runtime
Dividing the script's word count by a comfortable speaking pace gives the runtime in minutes and seconds. A conversational 150 words per minute is a solid default for narration. Reading a script aloud to time it is slow and variable, so a word-based estimate lets editors lock a runtime before recording begins.
Formula
Script to Runtime
Runtime = script words / speaking speed
- speaking speed
- Spoken words per minute, about 150 for narration
