What is a TikTok Duet?

A TikTok Duet allows you to create content side-by-side with another user’s video. You can react, collaborate, mimic, add commentary, sing along, or even tell the other half of a story—all within one screen.

Duets are a fantastic way to:

  • Boost visibility by leveraging trending content
  • Tap into the audience of popular creators
  • Show off your creativity in a unique format

How to Do a Duet on TikTok (2025 Version)

Step 1: Find the Video You Want to Duet With

Browse your TikTok feed or search for a creator/video you’d like to duet with. Pro tip: Duet trending or viral videos for more exposure.

Step 2: Tap the “Share” Button

Once you’re on the video, hit the arrow icon (Share) on the right-hand side.

Step 3: Select “Duet”

From the sharing options, tap “Duet”. If the option is greyed out, the creator has disabled duets for that video.

Step 4: Choose Your Layout

TikTok now offers multiple duet layouts:

  • Side-by-side (classic)
  • Top-bottom split screen
  • React (your video appears in a small window)
  • Green screen duet

Pick the format that works best for your idea.

Step 5: Record Your Part

Now comes the fun part—record your video alongside the original. Add filters, effects, or even voiceovers if needed.

Step 6: Add Captions, Hashtags & Description

Include a compelling caption and use trending hashtags like:

  • #DuetThis
  • #TikTokDuet
  • #DuetChallenge2025
  • #ReactWithMe
  • #ViralDuet

Step 7: Post & Engage!

Tap “Post”, then reply to comments, share your video on Instagram Reels, and engage with other duet creators to grow your reach.
