# Instagram Reels Captions > There are two ways to add Instagram Reels captions: the Captions sticker in Instagram's mobile app, or captions burned into the video before upload. Kenerate does the second: upload the 9:16 clip, choose the Middle position, which the tool calls Reels style, pick a style and post the captioned MP4 to Reels or YouTube Shorts.

Edit the Reel first — Finish cuts and music, then export 9:16 under 4 minutes and 100 MB. 2. Upload it to Auto Subtitles — MP4, MOV or WebM; sign in with a verified email. 3. Set Position to Middle — The tool's Reels-style option centres the captions. 4. Pick a style and shadow — Glide Pop or Rizz to highlight words; Mid or Max shadow on bright scenes. 5. Download, then post — Upload the MP4 as a Reel and as a Short; skip the Captions sticker for that post. ## In depth ### Instagram's Captions sticker, briefly In the Instagram app, the Captions sticker transcribes a Reel's speech once you add it while editing. Kapwing's May 2024 guide describes four preset styles — classic, typewriter, scroll and fade — and one caption position for the whole video, set in the mobile app [1]. It's quick for a phone-made Reel, less so for a series that needs one consistent look. ### Three minutes on both platforms Instagram raised the Reels limit to three minutes in January 2025 [3], and YouTube treats square or vertical uploads up to three minutes as Shorts [4]. Both fit inside Kenerate's 4-minute, 100 MB limit, so you caption the whole clip in one pass instead of cutting it into parts. ### Design around the buttons Both apps cover parts of the vertical frame with their own interface. - Keep captions centred: like, comment and share buttons stack on the right. - Leave the bottom of the frame for the username and post text. - Use Top only when the lower half holds the action, such as hands or food. - Use a Max shadow over bright skies and white walls. ### Instagram's closed captions vs yours Instagram can also generate closed captions with speech recognition, which viewers control themselves [2]. If your Reel already has burned-in captions, a viewer with captions switched on may see both. Burned-in captions win when the look matters; Instagram's own captions win when viewers want control.

A: In Instagram's mobile app, add the Captions sticker while editing a Reel and it transcribes the speech; Kapwing's guide notes the sticker offers four preset looks and one placement for the whole video. Instagram can also show automatic closed captions that viewers control. For styled captions that are part of the file, burn them in with Kenerate before posting. Q: Can I use the same captioned video for Reels and Shorts? A: Yes. Both are vertical, and both now take videos up to three minutes, which fits inside Kenerate's 4-minute limit. Caption the 9:16 clip once in the Middle position, download the MP4 and upload that same file to Instagram and YouTube. Skip each app's own caption tool for that post so viewers don't see two sets. Q: Why use burned-in captions instead of the Captions sticker? A: The sticker is quick but limited to the app's preset looks and one placement, and it lives only on that Instagram post. Burned-in captions travel with the file: 10 styles including word highlight, a text shadow setting, 1080p HD, and the same look on Reels, Shorts and anywhere else. The trade-off is that you can't edit words afterwards. Q: How long can a Reel be for captions? A: Instagram supports Reels up to three minutes, and Kenerate captions clips up to 4 minutes and 100 MB, so a standard Reel fits in one run. Captioning takes about 1–3 minutes. If your file is over 100 MB, export it again from your editor at a lower bitrate before uploading; the captioned version comes back at 720p or 1080p. Q: Which caption style works best on Reels? A: Glide Pop and Rizz are the most Reels-like choices because they highlight the word being spoken. Glass suits busy or bright backgrounds, Lowkey suits footage where the picture leads, and Fusion's short bursts suit fast talkers. Whatever you choose, keep it consistent across a series so your Reels are recognisable in the feed. Q: Can Instagram viewers turn my burned-in captions off? A: No. Burned-in captions are part of the picture, so everyone sees them, including people who never switch captions on. That's the point for muted scrolling, but it also means a typo stays. Check the Original vs Captioned preview carefully, and if a word is wrong, run the clip again with the spoken language pinned. ## Related pages - Add subtitles to video: https://kenerateai.com/add-subtitles-to-video - TikTok captions: https://kenerateai.com/tiktok-captions - YouTube subtitles: https://kenerateai.com/youtube-subtitles - Caption maker: https://kenerateai.com/caption-maker - Submagic alternative: https://kenerateai.com/submagic-alternative ## Sources - Kenerate Auto Subtitles (tool): https://kenerateai.com/app/tool/subtitles - Kapwing — How to add auto-captions to Instagram Reels (2 May 2024), checked 3 October 2026: https://www.kapwing.com/resources/instagram-reels-captions/ - Instagram Help Center — Manage closed captions for your reels, checked 3 October 2026: https://help.instagram.com/7487270478066359/ - Social Media Today — Instagram officially expands Reels length to 3 minutes (January 2025), checked 3 October 2026: https://www.socialmediatoday.com/news/instagram-officially-expands-reels-length-3-minutes/737766/ - YouTube Help — Understand three-minute YouTube Shorts, checked 3 October 2026: https://support.google.com/youtube/answer/15424877
