Tweet Length Checker

Count tweets with the 280-character limit, emoji support, and automatic 23-character t.co URLs before you publish.

Input

URLs are counted using Twitter's 23-character t.co rule. Include https:// so we can apply it.

Plan the length of your thread so we can warn you when the copy exceeds it.

Hold space for hashtag banks, CTAs, or tracking codes you paste later.

About the Tweet Length Checker

The Tweet Length Checker mirrors how X/Twitter validates copy so campaign managers can confirm launch announcements, support replies, and witty posts fit before approvals. It counts every emoji, newline, and domain with the 23-character t.co rule, keeping production tweets identical to the text you sign off on.

Key Features for Social Teams

Applies the 280-character limit with automatic 23-character t.co shortening for every domain you paste.
Counts emojis, line breaks, mentions, and hashtags exactly like X to avoid last-minute edits.
Highlights when your draft exceeds the tweets you allotted and shows how many posts are required.
Runs entirely in your browser, so embargoed copy and customer replies never leave your device.

How to Use the Tweet Length Checker

1

Paste or write your tweet, including mentions, emojis, hashtags, and the landing page domains you plan to promote.

2

Whenever you reference a site, include the full URL (for example https://minitoolstack.com/tools) so the checker shortens it to 23 characters just like t.co.

3

Optionally set how many tweets you want in the thread and reserve characters for a hashtag bank, CTA, or tracking code.

4

Run the checker to review used characters, remaining space, and guidance notes, then adjust copy until everything fits.

Common Mistakes to Avoid

Leaving off https:// in front of a domain, which prevents the checker from treating it as a link.
Pasting formatted text from docs with curly quotes or double spaces; clean the copy to avoid hidden characters.
Relying on the raw character count instead of the adjusted value that includes URL shortening and reserved space.

Example Scenarios

Announce a product update linking to https://brand.com/new-feature with emoji and a CTA.
Draft a support reply that must include a tracking domain plus a pre-approved hashtag bank.
Plan the opener of a thought-leadership thread to see whether it fits in one tweet or requires two.

FAQ

Does this follow the 280-character rule?

Yes. Each tweet is capped at 280 characters, and we show how many tweets you need if you run over.

How are domain names and URLs counted?

Every http or https link is normalized to 23 characters to match the t.co shortener, no matter how long the original domain is.

Can I plan a thread with this?

Set the maximum tweets in the input and the checker will flag when the copy spills into an extra post.

Is my draft stored anywhere?

No. Everything runs locally in your browser, so sensitive or embargoed text stays on your device.
