Enter the word count and words per minute rate into the calculator to determine the script length. This calculator can also evaluate any of the variables given the others are known.

Script Length Formula

The following formula is used to calculate the script length.

SL = (WC / WPM) * 60


  • SL is the script length (seconds) WC is the word count of the script WPM is the words per minute rate (words per minute)

To calculate the script length, divide the word count of the script by the words per minute rate. Then, multiply the result by 60 to convert the time from minutes to seconds.

What is a Script Length?

Script length refers to the number of pages or words in a script, typically for a film, television show, play, or radio program. It is often used as a rough estimate for the duration of the final product, with one page of a screenplay usually equating to about one minute of screen time. However, this can vary depending on factors such as dialogue speed, action sequences, and editing style.

How to Calculate Script Length?

The following steps outline how to calculate the Script Length using the given formula:

  1. First, determine the word count of the script (WC).
  2. Next, determine the words per minute rate (WPM).
  3. Next, use the formula SL = (WC / WPM) * 60 to calculate the script length (SL) in seconds.
  4. Finally, calculate the Script Length.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Word count of the script (WC) = 500

Words per minute rate (WPM) = 120
