Character limit
A character limit is the maximum amount of text allowed in a post or another publishing field.
Definition
A character limit is the maximum amount of text allowed in a post or another publishing field. The applicable limit depends on the platform, account capabilities, and publishing surface. A draft that fits in one destination may need editing before it can be used elsewhere.
For the standard formats covered here, X allows 280 characters for non-Premium posts and up to 25,000 for Premium longer posts, while a standard Threads post allows 500 characters. Links and special characters can be counted according to platform-specific rules, so a simple visual estimate is insufficient.
Leave room for numbering, mentions, and any closing link when preparing a sequence. If a post is too long, split at a complete thought rather than cutting a sentence mechanically. Preview every resulting entry to ensure the argument still flows and references remain clear. A higher limit provides space; it does not require filling that space.
Example
A 310-character X draft for a non-Premium account needs shortening or splitting before publication.
How to apply it
Write the full argument in a document, then split at complete thoughts to fit 280 characters on a standard X account or 500 on Threads. Leave 25 characters in each X post for a 1/n label and a mention. If a sentence still overruns, move the example to the next reply instead of cutting the verb. For a Facebook Page parent post you can go longer, but keep the first 2 lines readable in the feed.
Preview every split before you schedule. If post 3 ends mid-clause, merge it with post 4 even if that means a 6-post thread becomes 5. Premium's 25,000-character room is optional. Use it only when a table or legal caveat truly belongs in one item, not as a reason to skip a reply chain your readers can skim.
Common mistakes
- Cutting a sentence in the middle to hit 280 characters instead of moving the example.
- Forgetting that numbering and mentions count toward the same limit as the body text.
- Filling a 25,000-character Premium post because the space exists, not because readers need it.
