How to use these caption templates
- Pick the template that matches the post's goal — announce, educate, prove, or sell.
- Copy it and replace every {placeholder} with specifics. Real numbers, names, and dates beat adjectives.
- Rewrite the first line until it would make you stop scrolling. That line does most of the work.
- Add 3–5 relevant hashtags if the platform uses them, then check the length against the table below.
A caption formula that works on any platform
Most strong captions follow the same three-part shape. The templates above are short versions of it:
- Hook:a first line that makes a promise or raises a question. "We almost didn't ship this" works better than "Excited to announce".
- Value: the one thing you want people to know — the tip, the story, the result, the offer.
- Call to action: a single next step: comment, save, share, or click the link.
Caption length limits by platform (2026)
The limit is the most you can write. The visible column is how much people see before the platform cuts it off, which is why the first line matters so much.
| Platform | Character limit | Visible before truncation |
|---|---|---|
| 2,200 | About 125 before “more” | |
| TikTok | 4,000 | A line or two over the video |
| 3,000 | About 140–210 before “see more” | |
| 63,206 | Longer posts truncate in feed | |
| X (Twitter) | 280 (free accounts) | All of it |
| Threads | 500 | All of it |
| Bluesky | 300 | All of it |
| 500 (description) | Title shows first | |
| YouTube | 5,000 (description) | First 2–3 lines |
Which caption template should you use?
- Announcements and launches: for new products, features, hires, or milestones. Lead with what changes for the reader, not with how excited you are.
- Testimonials:let a customer's words carry the post. Quote them exactly and name them (with permission).
- Educational tips: the most saveable format. Number the tips and keep each one short.
- Behind the scenes: builds trust between promotions. Show process, people, and mistakes.
- Engagement questions: easy-to-answer questions get more replies than open-ended ones.
- Promotions: state the offer, the deadline, and where to go. Keep these to a minority of your posts.
