Count every character
On the sample sentence below (44 characters): 236 left under the 280-character X limit. Replace it with your own text and pick a platform.

Character Counter
Paste anything — a post, a bio, a text message, a headline — and count every character instantly: with and without spaces, words, lines, and reading time. Then check it against the real limits of X, Threads, Bluesky, Instagram, TikTok, LinkedIn, and SMS before you hit send.
Why character limits still matter
Every platform draws its line in a different place, and crossing it either cuts you off or silently truncates you. X stops you at 280 characters per post. Threads gives you 500, Bluesky only 300. Instagram and TikTok captions run to 2,200. LinkedIn posts get 3,000. And an SMS is 160 characters on the classic GSM alphabet — type one emoji and the encoding flips to UCS-2, where a single message holds only 70. Count before you write the punchline, not after.
Output · formula · meaning
| Output | Formula | What it means |
|---|---|---|
| Characters | every letter, digit, space, and punctuation mark | 44 in the sample sentence — the number every platform limit is measured in. |
| Without spaces | characters minus whitespace | Useful for minimum-length rules and tight headlines. |
| Words | whitespace-separated tokens | 9 in the sample — the metric essays and articles use. |
| Lines | newline-separated rows | Bios and addresses often limit lines, not characters. |
| Limit status | limit − characters | How many you have left — or how many to cut. |
Worked example: fitting an X post
Draft: “Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty.” That is 113 characters — select X / Twitter post — 280 and the verdict shows 167 left. Room for a hashtag and a link (links always count as 23 characters on X, t.co-shortened). Now try it against SMS — 160: 113 fits one message, but add 48 more characters and you spill into a second segment.
Who uses this
- Social media managers: drafting posts that must land under 280, 500, or 2,200 without getting cut off mid-word.
- Job seekers: LinkedIn headlines (220 characters) and summaries where every character is resume real estate.
- Marketers: SMS campaigns where a 161st character doubles the cost — one extra segment per recipient.
- Developers & SEOs: meta titles (~60 characters before Google truncates) and YouTube titles (100).
Accuracy & limitations
Counts are Unicode code points — an emoji counts as one here. Platforms differ: X uses a weighted count (most characters 1, some CJK ranges 2; links always 23), and SMS encoding flips from GSM-7 (160/message) to UCS-2 (70/message) the moment you type an emoji or accented character. If you are posting at the edge of a limit, confirm with the platform’s own counter. Spaces, tabs, and newlines all count as characters everywhere.
Counting words instead? The word counter tracks words, sentences, paragraphs, and reading time — and changing the letter case is one click away with the case converter.

How many characters can an X (Twitter) post be?
280 characters. Links are always counted as 23 characters (t.co-wrapped) no matter how long the real URL is, and most characters count as one under X’s weighted system. Select “X / Twitter post — 280” above to check your draft.
How many characters can an Instagram caption be?
2,200 characters, with up to 30 hashtags. Captions truncate in the feed after about 125 characters with a “more” link — so the hook still matters more than the limit.
How many characters can a Threads post be?
500 characters — nearly double X’s limit. Bluesky, by contrast, allows only 300.
How many characters fit in one SMS?
160 characters on the standard GSM-7 alphabet. Longer texts split into segments of 153 characters each, and you are billed per segment. Type an emoji and the encoding switches to UCS-2: then a single message holds only 70 characters.
Do spaces count as characters?
Yes — on every platform. Spaces, punctuation, line breaks, and emoji all consume characters. The “without spaces” tile shows the count with all whitespace stripped, which some minimum-length rules use.
Why does my emoji count differently on different sites?
An emoji is one visible character but can be two code units (a surrogate pair) in UTF-16, and platforms weight them differently — X’s weighted count, SMS’s encoding flip. This counter counts each emoji as one; at the edge of a limit, verify on the platform itself.
What is the difference between a word counter and a character counter?
A word counter measures whitespace-separated tokens (essays, articles, reading time); a character counter measures every symbol (posts, bios, SMS, headlines). Use the word counter when a teacher or editor set the limit in words.
How long should a meta title be?
Around 60 characters — Google truncates titles in search results at roughly 580 pixels, which works out to about 55–65 characters depending on letter widths. Select “Meta title / SEO — ~60” to check.
