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.

Is this a separate counter built just for X?

No — it is the same multi-platform counter as our general caption and character counter, arranged so X’s row and questions are easy to find from a X-specific search.

Does the counter store or send my caption anywhere?

No, counting happens entirely in your browser as you type; nothing is uploaded, saved, or sent to a server.

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 check the same caption against other platforms too?

Yes, the same text is measured against every platform SkedCast supports at once, so you can see which platforms it fits and which ones need a shorter variant.

How many hashtags should a X caption use?

It varies by platform and audience, but a smaller, relevant set of hashtags usually performs better than the maximum allowed; the hashtag count helps you stay deliberate about it.

Does the X character limit include spaces?

Yes — this counter counts every character you type, including spaces, the same way X does: by grapheme cluster (what you actually see) rather than raw code points, so a word count and a character count will always read differently for the same caption.

Is the limit different for a X bio, comment or ad than for a post text?

This counter measures the post text limit specifically. X’s bio, comments, ads and other surfaces often carry their own separate limits that this tool does not check — use the X row above only for the post text you are counting.

X character counter

This X character counter shows how long your caption is against X’s real post text limit of 280 characters, live as you type. It is the exact same multi-platform counter behind our general caption and character counter — this page just leads with the X row and answers X-specific questions below it. The same text is checked against every other platform SkedCast supports at the same time, so you can see whether one caption fits everywhere before you decide what to post where.

How to 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.

Worked examples

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.

3 hashtags, 42 words, one pass

A caption with 3 hashtags and 42 words shows all three counts — characters, words and hashtags — next to the X row and every other platform’s row, updating as you type.
