Determining the Best Length for Your Video to Improve Effectiveness

When it comes to video production, clients always ask what’s an effective video length. Our answer is almost always, it depends.

Determining an effective video length is impacted by the elements of your video strategy, such as:

  • The story you want to tell. It’s the key element in your decision. 
  • Where videos will be shared. Just as different story objectives call for different lengths, every social media and digital platform has different ideal video lengths that users respond best to. Those lengths affect viewer engagement. For instance, videos on Instagram that are an average of 26 seconds receive the most comments from Instagram users. 
  • Our (short and getting shorter) attention span. Studies indicate the average adult attention span is only eight seconds. Meanwhile, recent research from Facebook shows 47% of the value of an online video (i.e., the salient message) is delivered in the first three seconds. 
  • Mental knowledge versus emotional connection. In 2020, the average number of online videos over 20 minutes grew 66%, which could indicate an increasing demand for longer educational content like webinars.

Video Length Best Practices

To find the sweet spot for your video length, consider these tips:

  • Capture viewer attention quickly. Cater to our short attention spans by getting to the point fast. Ideally, aim for your most important message in the first quarter of your video. Another best practice is to repeat your message within the video.
  • Test video length to find what works for your audience. Consider whether the viewer is a new prospect or a loyal customer and whether they requested to view your video. 
  • Track your success. Use video analytics to find out the length where viewing drops off, what changes to make to increase conversions, and make good on your return on investment (ROI).
