Enter the number of slides and the total presentation time (min) into the Calculator. The calculator will evaluate the Slides Per Minute. 

Slides Per Minute Formula

SLPM = S / T

Variables:

  • SLPM is the Slides Per Minute (slides/min)
  • S is the number of slides
  • T is the total presentation time (min)

To calculate Slides Per Minute, divide the number of slides by the total presentation time.

How to Calculate Slides Per Minute?

The following steps outline how to calculate the Slides Per Minute.

  • First, determine the number of slides. 
  • Next, determine the total presentation time (min). 
  • Next, gather the formula from above = SLPM = S / T.
  • Finally, calculate the Slides Per Minute.
  • 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.

number of slides = 59

total presentation time (min) = 20

Frequently Asked Questions

How can I improve my Slides Per Minute (SLPM) for a better presentation?
Focus on creating concise and visually appealing slides, practice your presentation to better manage your time, and adjust the amount of content based on your speaking speed and audience engagement.

Is there an optimal range for Slides Per Minute in presentations?
While there’s no one-size-fits-all answer, a common recommendation is 1-2 slides per minute. This range allows for sufficient detail without overwhelming the audience, but it can vary based on the content and presentation style.

Can using more slides in a presentation be more effective?
It depends on the context. More slides can be effective if they’re not text-heavy and are used to visually complement your spoken words, keeping the audience engaged. However, too many slides can also distract or overwhelm the audience.

How does the complexity of slides affect the Slides Per Minute rate?
Complex slides that contain a lot of information or require detailed explanation can decrease the SLPM rate, as they take longer to present. Simplifying slides and focusing on key points can help maintain an effective pace.
