This article is built around three core questions:

• How users behave across Instagram Reels and TikTok posts
• How Instagram Reels vs TikTok engagement and reach differ by platform
• How brands and creators should adapt strategy using TikTok vs Instagram Reels data

What Is an Instagram Reel in 2026?

Instagram Reels are short-form videos published inside the Instagram ecosystem.

They appear across multiple surfaces:

1. Instagram Feed
2. Instagram Stories
3. Explore tab
