There’s no one perfect length, but research and industry advice point to some sweet spots:
- TikTok themselves suggest around 21-34 seconds for in-feed videos. SocialBu+3loomly.com+3SocialBu+3
- Some older forums suggest even shorter: “between 7 and 15 seconds” can work well. Student Filmmakers Forums+1
- On the other hand, analysis shows videos of 1-2 minutes (or even slightly longer) can perform well if they keep viewers’ attention—because total watch time is a strong signal. socialinsider.io+1
- General advice: aim for content that feels complete yet concise; you don’t want to drag or lose viewers.
Writing-education note: Think of your video like a mini-essay or scene. You need a strong hook (intro), a middle (development or reveal), and a wrap-up (call to action or memorable end). If it’s too long without structure, you risk losing your audience.
My recommendation: For most creators, aim for
~15-30 seconds. If your story or content justifies more time (and you can keep engagement high), go up to ~60 seconds. If you go much beyond that, make sure you’re really delivering value or a narrative.
Most popular video types & content ideas
Here are some of the content categories and formats that are working well on TikTok:
- Trend-based videos (using trending sounds, memes, challenges) are consistently effective. Zubtitle+2RecurPost+2
- Educational / How-to / Life hacks / DIY. The “help-me” type content draws engagement because people learn something. fohr.co+1
- Behind-the-scenes, day-in-the-life, transformation videos (before/after) appeal because they show something happening, a journey. Sprout Social+1
- Entertainment: dance, comedy, pranks, fashion, beauty. Big reach categories. IZEA Worldwide, Inc+2brandbassador.com+2
- Relatable moments, small narrative or storytime (people sharing personal experiences). fohr.co
Writing-education note: When planning content, use the classic structure:
- Hook: grab attention in first 2-3 seconds
- Body: deliver the main message, story, or transformation
- Resolution / CTA: finish with something that invites engagement (comment, share, follow).
Also, aim for clear, simple language and visuals—TikTok is fast-moving, so clarity matters.
Tips to make your video good
Here are some practical tips for making a strong TikTok video:
- Hook immediately – The first few seconds matter. You might open with a question, a surprising visual, or a bold statement to stop scroll-through.
- Vertical format & mobile-first design – TikTok is mobile; make sure your video uses full screen (9:16) and is visually engaging.
- Clear visual focus – Whether it’s you talking, a transformation, a DIY process—make sure the viewer knows what they’re watching and what the payoff will be.
- Good lighting & sound – Even simple videos benefit from decent lighting and clear audio.
- Keep pacing tight – Especially if you’re doing a short video, get to the point; avoid long pauses or irrelevant filler.
- Edit for impact – Use jump cuts, text overlays, on-screen captions (many viewers watch muted), transitions if appropriate.
- Include a call to action (CTA) – “Follow for part 2”, “Comment your thoughts”, “Share if you’ve tried this” – helps drive engagement.
- Use trending sounds/hashtags – Helps discovery. But also make sure the content itself is original or has your unique twist.
- Stay consistent – Post regularly, keep your style or theme recognizable so your audience knows what to expect.
- Analyze and iterate – Look at analytics: which videos get watch-through, shares, comments. Do more of what works, less of what doesn’t.
Writing-education note: Think of your caption and on-screen text as ‘micro-writing’. It should be concise, correct (grammar/punctuation), and compelling. Use active voice (“Try this hack”) rather than passive (“This hack can be done by you”).
