How Long Should a Webinar Be? The Optimal Webinar Length

Unsure how long your webinar should be? Our guide has you covered. Learn the optimal length, factors to consider, and how to create a memorable experience for your attendees.
May 5, 2023

Webinars have become an increasingly popular tool for businesses to connect with their audience, generate leads, and grow their business. As more and more types of communication move online, webinars offer a convenient and cost-effective way to connect with a global audience. However, despite the increasing number of webinars, people still have many questions, particularly when it comes to planning. Some of the most common questions include which day is best for a webinar, whether it should be live-streamed or on-demand, and when is the best time to broadcast it.

But one of the most critical questions regarding webinar planning is: how long should a webinar be? It's a crucial question because the length of a webinar can significantly affect the audience's experience, including their engagement and conversion rates. Given people's busy schedules, it's essential to consider the optimal length that suits your audience's needs and aligns with your intended outcomes. If you advertise a long webinar on the registration page, it's unlikely that many people will attend. Therefore, setting realistic expectations regarding the duration of a webinar is crucial for ensuring higher attendance rates and engagement levels during the event.

This blog post will delve into determining the optimal length of a webinar and the various factors to consider before deciding its duration.

How long should a webinar be? 

There is no one-size-fits-all answer to the ideal length of a webinar. The ideal duration for a webinar will vary depending on the webinar format and the topic being covered. Typically, webinars last for around 60 minutes, allowing ample time for introductions (between 5 to 7 minutes), the presentation itself (40 minutes), and a Q&A session at the end (10 to 15 minutes). 92% of webinar attendees say they benefit from a Q&A session at the end.
Sometimes, a brand with high customer engagement or a lengthy topic may opt for a webinar closer to 90 minutes. It's crucial to avoid running webinars too long, as this can cause audience drop-offs and potentially harm future engagement and attendance. However, it's worth noting that the duration of a webinar may vary based on several factors, such as the format, the number of speakers involved, and the level of audience interaction. Therefore, it's essential to remain adaptable and flexible when determining the optimal length for your webinar.

It's important to strike a balance between providing valuable information and keeping the audience engaged. If a webinar exceeds the recommended time frame, attendees may lose interest and not return for future events. Be sure to communicate the expected length of the webinar early on to manage audience expectations and consider the best time to host the event to maximize attendance. By creating engaging webinars, businesses can connect with their audience on a personal level, showcase their expertise, and establish themselves as thought leaders in their field.

Why does webinar length matter?

Here are three reasons why the duration of a webinar is important.

1. Audience engagement

Keeping audiences engaged for long periods is hard, so sticking to a schedule that works for you and your attendees is important to maintain their attention.

2. Staying on topic

A shorter webinar that delivers the content effectively without compromising quality is better than a longer one that gets sidetracked with unnecessary fillers and leaves attendees needing clarification on what's being communicated.

3. Preventing drop-offs

Attendees can quickly drop out of a webinar by clicking a button, so keeping the webinar to a reasonable length can help prevent disinterest and keep them from leaving the platform. Participants may start to go if the webinar is extended longer than 20 minutes, as they have other things to do during the day and a time limit in mind.

5 factors to consider when determining the length of a webinar

1. Purpose of the webinar

The length of the webinar should be determined by its purpose. Is it an informational webinar or a product/service demo? A panel discussion or a Q&A session? The format and goals of the webinar will help determine its ideal length.

2. Audience attention span

The length of the webinar should also consider the audience's attention span and schedule. Consider your audience's demographics, interests, and how long they will likely engage with the content. Research has shown that the average human attention span is around 8 seconds, which can vary depending on age and other factors. Therefore, keeping your webinar concise and engaging is important to hold your audience's attention.

3. Content & topic complexity

The webinar should be long enough to cover the key points but not so long that it becomes tedious. Remember that participants seek valuable and engaging content, not just filler material. If your topic is straightforward, you can cover it in less time. However, explaining and exploring may require more time if your topic is more complex.

4. Audience interaction & engagement

Consider how much interaction & audience engagement you want with your audience during the webinar. Keeping your audience engaged throughout the webinar is crucial to ensure that they retain the information and take the desired action. Therefore, your webinar should be long enough to cover the topic comprehensively while keeping your audience engaged.

5. Presenter/s

The number of presenters and their expertise should also be considered as a factor before deciding the webinar time. If there are multiple presenters, they would need more time for introductions and transitions. If the presenter is an expert in the field, they can cover more material in less time.

All these factors must be considered when determining the ideal length of a webinar. Ultimately, the goal is to provide valuable content that engages the audience and leaves them with a positive impression.

Ultimately, the goal is to deliver valuable content effectively without compromising quality and  leaving enough time for your audience to interact.
