Enter the total number of words, and your words per minute speech speed into the calculator to determine the total length of a speech.

Speech Length Formula

The following formula is used to calculate the length of a speech.

T = W / SS
  • Where T is the total time
  • W is the total number of words
  • SS is the speaking speed in words/min

To calculate the speech length, divide the total number of words by the speaking rate.

Speech Length Definition

A speech length is defined as the total time it takes to perform a speech or presentation.

Speech Length Example

How to calculate speech length?

  1. First, determine the total number words.

    Measure the total number of words in the speech.

  2. Next, determine the speaking rate.

    Determine the average speed at which you speak.

  3. Finally, calculate the speech length.

    Calculate the time of the speech using the equation above.


How long should a speech be?

A speech should be as long as it needs to be to convey the information being presented. No shorter and no longer than that exact length. What that length is, is a little hard to determine. If you get your point across concisely and quickly, it can be good enough.
