There isn’t a single, apples-to-apples count of people watching Instagram Reels versus TikTok. But if you’re comparing potential audience size, Instagram Reels may have the edge: Instagram’s overall audience is larger than TikTok’s. That doesn’t mean every Instagram user watches Reels, or that your videos will automatically get more views there.
TikTok is built around short-form video, so it can be especially effective for reaching people who actively browse videos and discover unfamiliar creators. Reels can help you reach Instagram users who already follow your business, as well as new viewers through recommendations. Which platform gets more views depends on the content, audience, and distribution—not just the size of the app.
Start with the people you want to reach. If your customers are active on Instagram and your business already uses the platform, Reels can fit naturally into your existing presence. You can use them to introduce products, show how something works, or give followers a quick look at your brand.
Prioritize TikTok if your audience spends time there and your team can make videos that feel at home in its fast-moving, trend-aware feed. It can be a strong place to test entertaining concepts, demonstrations, and creator-style storytelling. A trend is useful only when it suits your product and brand; copying one without a clear connection can distract from what you offer.
Post comparable versions of a video on both platforms, then review performance after a consistent period. Look beyond total views: compare watch time, completion, shares, saves, profile visits, and the actions that matter to your business, such as product-page visits or inquiries. A high view count is less valuable if it doesn’t reach likely customers or prompt meaningful interest.
Make small edits for each platform rather than assuming one upload will perform identically everywhere. Adjust the opening, captions, and call to action while keeping the central idea consistent. Our team’s guide to Instagram Reels vs. TikTok for business covers how to choose a platform and adapt your approach.
You can reuse the core idea, but tailor the edit, captions, and opening to each platform. Compare the results separately so you can see where that content connects with your audience.
