Quick answer: A launch tweet is a single post that announces a product on X. The limit is 280 characters, the link belongs in the first reply, and the first line is the only part many people read.

Here's the structure that works, plus what to avoid.

The structure

Four lines, in this order:

  1. The hook. The problem or the claim, in a way a target user recognizes.
  2. The product. What it is and what it does, one sentence.
  3. The proof or detail. A specific fact, a screenshot, or a short workflow.
  4. The CTA. What to do next.
[Hook: the problem]

[Product] does [what], so you [result].

[Detail or proof, one line.]

[CTA: link in the first reply]

A link in the main tweet historically reduces reach on X, so the standard practice is to post the tweet, then reply with the link and pin that reply. This keeps the main post clean and avoids the link penalty.

The reply is also where you can add the "read the full launch" note, the gallery, and any follow-up links.

Length and shape

  • The first line should be under 50 characters. It's the scroll-stopper.
  • Keep the total under 200 characters when you can; long launch tweets that look like paragraphs get skipped.
  • Line breaks matter. Four short lines read more than one block of text.
  • The 280-character limit is the current cap for standard accounts.

What the hook can be

A hook is one of:

  • A statement of the problem: "Most launch graphics are made the night before launch."
  • A claim: "You don't need a designer to make a Product Hunt gallery."
  • A specific moment: "Spent three hours resizing one screenshot for nine platforms."
  • A bold comparison: "The AI made the deck. We made the deck editable."

The hook craft is covered in how to write a hook.

What to avoid

  • The feature list. "A, B, C, and D" in one tweet is noise.
  • The tagline. "The world's first X" is a press release, not a hook.
  • Hashtags in the launch tweet. One or two at most, and only if they're the actual search community.
  • A vague CTA. "Check it out" is weaker than "Try it free, no sign-up."
  • A different story in the image. The attached image should repeat the claim visually, not introduce a new slogan.

The image

The image is 1200 × 675 (16:9), per the X image size guide. It should be the product or a clear visual, with the headline legible in the feed. The same card is usually the Open Graph image.

Launch day as a set

The single launch tweet is part of a five-post set, each with a different angle: the announcement, the how-it-works, the comparison, the detail, the recap. The cadence is in the X launch posts guide and the hour-by-hour timeline.

Frequently asked questions

Can I write the launch tweet first and build the rest from it? Yes, it's the tightest format and forces the clearest statement. If you can't say it in 200 characters, the positioning isn't clear.

Should the link be in the tweet or the reply? The first reply is the standard practice; the reach is generally better and the link is still one tap away.

How do I announce a Product Hunt launch on X? Same structure, with the Product Hunt link in the first reply and the gallery image attached.

How many launch tweets should I post? One main announcement, then four angle posts across the day.

What if the product is complex? Put the one-sentence job in the tweet and the detail in a thread, per how to write an X thread.

Write the hook first, and cut it until a target user would recognize the problem on their own feed.
