Do more people in an image automatically lead to better performance? Many brands still believe so, but the reality is quite different. Especially on Instagram, where visual impressions are determined in a split second, image composition and motif are what decide whether content stops the scroll, receives likes, or gets ignored.
Our analysis shows: Most brands are using the wrong format. Instead of relying on data, habits dominate. This has significant consequences for reach and engagement. To provide reliable answers to the question of how many people in a post actually lead to the highest reach and engagement, we analyzed more than 3,000 images, carousels, and reels.
Instagram Study: How the Number of People Shown Affects Performance
Our analysis reveals clear differences depending on the number of people featured in a post. What is particularly striking is that the most commonly used format is not the most successful, and depending on the KPI, the top performers shift significantly.

A look at the distribution of content initially paints a clear picture. Almost half of all analyzed posts (46%) feature exactly one person in the visual. This format thus clearly dominates the Instagram feeds of many brands. Its popularity comes as little surprise, as individuals are easy to portray, can be used in various ways, and appear to be a safe choice at first glance.
However, the data tells a different story. Despite their widespread use, posts featuring one person only achieve average performance across all metrics. In other words, the most commonly used format is not the most successful.
Many brands apparently rely more on common patterns than on actual performance, making a common strategic mistake. If you want to optimize your content based on data, it’s important to start questioning these established routines.
Two People Maximize Visibility in the Instagram Feed
When looking at reach on Instagram, there are clear differences depending on the number of people shown in the visual. Posts featuring two people achieve the best results with a reach of 5.23% per follower, placing them roughly 85% above average (2.8%). Group photos with four or more people achieve the lowest visibility at 1.42%.
Two people seem to offer an optimal visual balance of clarity and action. Visible interactions like eye contact or gestures create an easily understandable visual story that people can quickly grasp when scrolling through their feed.
At the same time, two people create more energy and suspense than an individual without being too overwhelming. This combination makes it more likely that your posts will stand out as people swipe through their feed, making them want to look at your content for longer.
This is exactly where group photos lose their impact. Too many people make it difficult for viewers to navigate and lack a clear focal point, making content seem less “snackable” and more likely to be overlooked. The result is a lower scroll-stop rate and thus significantly less reach.

Two People Trigger the Most Interactions
Engagement numbers show a pattern similar to that of reach. Posts featuring two people achieve the highest interaction rate at 0.66%, while content without people falls significantly behind at 0.25%.

Two people seem to be particularly good at depicting social situations with which users can identify. Such dynamics invite engagement because they trigger interpretation, agreement, or personal experiences. This makes the content feel more authentic and provides more opportunities for likes or comments.
Posts without people (e.g., products, landscapes, or graphics) tend to lack precisely this emotional appeal. Without human points of reference or social cues like facial expressions or social interaction, content often feels more interchangeable and encourages less engagement. Instagram users may still view these posts, but are significantly less likely to actively engage with them.
Content Without People Gets the Most Shares
When it comes to shares, the situation is reversed. Although it achieves the highest overall reach and engagement, content featuring two people is shared the least (0.07% shares per reach). Posts without people achieve the highest share rate at 0.11%.
Content without people often focuses heavily on information, added value, or inspiration, for example in the form of infographics, quotes, or tips.
These types of posts tend to be educational rather than promotional, which increases their potential for sharing. Users are more likely to share content with their network if it appears to be immediately useful.
At the same time, the lack of personal connection that comes with posts without people can lower the social barrier for sharing. All these characteristics encourage shares and, consequently, distribution beyond one’s own community.

The number of shares per reach are a key ranking factor for the Instagram algorithm. Content that is frequently shared has a higher chance of being suggested to users who do not yet follow the account, thereby increasing visibility among new target audiences.
From Data to Strategy: The Ideal Number of People in a Post
Our findings show that there is no universal best practice for the optimal number of people appearing in a post. What matters most is defining the primary objective of the content and tailoring your posts accordingly.
Those who want to increase reach on Instagram and maximize engagement should specifically focus on posts featuring two people. They combine visual clarity with dynamism and ensure both visibility in the feed and engagement within your existing community.
When it comes to reaching new target audiences, however, content without people proves to be more effective. The high shareability of educational content increases the likelihood of reaching users outside your own community, thereby stimulating follower growth on Instagram.
Successful social media strategies deliberately combine different formats. Social media teams should always plan posts based on their specific goals and adapt them to their own industry and target audience, rather than sticking to a single dominant approach.
Conclusion: Use the Number of People in Your Posts Strategically
Our analysis demonstrates that the number of people in a post measurably affects its performance, although not in a consistent direction. Successful content isn’t created by using a single image composition but through purposeful combinations of different formats, strategic planning, and continuous optimization. Only those who optimize their content based on data, test different approaches, and regularly analyze their performance can improve their Instagram strategy in the long term.
