What is X’s character limit for a post text?

X’s post text limit is 280 characters, but X weighs links and emoji differently from a plain character count rather than counting what you see. It updates automatically if X changes the number, since the counter reads it from the same limit table SkedCast’s composer uses.

How does the counter measure length for X?

X uses its own weighted scheme instead of counting visible characters: every link counts as 23 characters and every emoji counts as 2, which the counter applies to the row.

Can I post text only on X (Twitter)?

Yes. X (Twitter) accepts a text-only post, up to 280 characters.

Will X (Twitter) cut off a long caption?

X (Twitter) does not truncate the text in the feed, so the whole post shows; the limit that matters is the 280-character maximum.

How many hashtags can an X (Twitter) post have?

SkedCast enforces no hashtag cap for X (Twitter); the practical limit is the 280-character text limit and what reads well.

What happens to a link in an X (Twitter) post?

It counts as 23 characters however long it is, and the post shows a link-preview card.

X character counter

X’s post text limit is 280 characters. Paste or type your text and this counter shows how many characters you have used and how many are left as you type, counting emoji and spaces the way X does. It checks the same text against every other network at once, so you can see where one version fits. X (Twitter) posts take up to 280 characters.

How do you use the X character counter?

Paste or type your X caption. Put your draft X caption or post text into the box; nothing you type is uploaded anywhere.
Read the X row first. Find X in the per-platform list to see its exact limit, the characters left, and whether you are over.
Check every other platform too. Scroll the same list to see the identical caption measured against every other platform SkedCast supports, all in one pass.
Watch words and hashtags. The summary above the list also counts total words and hashtags, so you can keep your hashtag set deliberate.
Trim or write a platform-specific variant. If the X row shows over-limit, shorten the caption or write a separate version just for X instead of cutting every version to the tightest limit.

What are the X (Twitter) rules to know?

X posts cannot exceed 280 characters (Premium long-form is not supported).
X cannot mix media kinds — up to 4 images, OR 1 GIF, OR 1 video, never a combination.
X supports at most 4 images, 1 GIF, or 1 video per post.
X does not support document/PDF attachments.

What does it look like in practice?

A long post on X (Twitter)

X (Twitter) does not fold the text behind "…more", so a 280-character post shows in full; the hard stop is 280 characters.

One link in an X (Twitter) post

A 60-character URL counts as 23, so a post with 200 characters of text plus that link counts as 223 of 280.

X’s real character limit

X’s post text limit is 280 characters, but X weighs links and emoji differently from a plain character count rather than counting what you see. That is the same number shown in the counter’s X row, and the same rule SkedCast’s own composer enforces before a post ships.
