Reels are Instagram’s short-form vertical video format: full-screen 9:16 clips with music, voiceover, text overlays, and native editing tools, launched in 2020 as Instagram’s answer to TikTok and also available on Facebook. Reels live in their own tab, appear in the home feed and Explore, and — crucially — are distributed by recommendation, so they routinely reach people who don’t follow you. Maximum length has been extended several times over the years; check the app’s composer for the current ceiling rather than trusting an old article.
Instagram has spent years signaling that short-form video is a growth priority, and Reels are the format with the most built-in paths to non-follower reach on the platform. For a scheduling strategy they are also the most portable asset you can make: the same vertical clip can run as a Reel, a TikTok, and a YouTube Short. One production session feeds three networks — as long as you export a clean file each time, since Instagram has indicated that visibly watermarked, recycled clips may be recommended less.
A bakery posts a 25-second Reel of a glaze being poured, opening on the pour itself rather than a logo card. Insights later show most of its reach came from non-followers via the Reels tab and Explore — an audience its photo posts, distributed mainly to existing followers, never touch. Same kitchen, same product; the format changed which distribution system picked it up.
Instagram’s insights report plays, watch time, interactions, and the follower/non-follower reach split per Reel. Watch retention above all: recommendation feeds reward clips people finish, so front-load the payoff into the first seconds. Publish Reels on a steady cadence at hours your audience is active, reuse each clip natively across TikTok and Shorts, and compare formats in your analytics monthly — the Reels that earn non-follower reach tell you what to make more of.
