Character Counter
Same text, two numbers: with spaces and without. The difference matters when a platform counts one and you counted the other.
With spaces or without?
Both numbers are on the screen because both are used. Social platforms count with spaces: a tweet of "hello world" is 11 characters, not 10. Forms that store a name, a coupon code or a URL usually count without spaces, and some count bytes rather than characters.
If a form rejects your text and the counter says it fits, the usual cause is one of three things: the form counts bytes (an emoji can take four), it trims whitespace before counting, or it measures pixels rather than characters.
Common limits, in characters
| Where | Limit | Counts spaces? |
|---|---|---|
| X / Twitter post | 280 | Yes |
| Instagram caption | 2,200 | Yes |
| Instagram bio | 150 | Yes |
| LinkedIn post | 3,000 | Yes |
| TikTok caption | 2,200 | Yes |
| YouTube title | 100 | Yes |
| SMS, plain text | 160 | Yes |
| SMS with emoji or accents | 70 | Yes, and each emoji costs more |
| Meta description (guideline) | ~155–160 | Yes |
| Page title (guideline) | ~60 | Yes |
The last two are guidelines, not hard limits: Google truncates by pixel width, so a title of 58 wide characters can be cut while 62 narrow ones survive. Treat them as sizing advice, not validation.
What counts as one character
- Letters, digits, punctuation and spaces each count as one.
- Accented letters such as é are one character in Unicode but often two bytes in storage. A byte limit is effectively halved for non-ASCII text.
- Emoji are the trap: a single emoji can be one visible glyph but several code points. Platforms that count UTF-16 units may charge two or more per emoji.
- Line breaks count as one character each on most platforms, and some convert them to two (CRLF).
Do not trust a counter for validation. If a form has a hard limit, test with the longest realistic input — an emoji, an accented name, a line break — rather than trusting a character count alone.
Questions
Why is my tweet counted as 282 when the counter says 280?
Most likely an emoji or a non-Latin character that X counts as two units, or a link that is shortened to a fixed length. The platform's own counter is the authority.
Does a space count in a meta description?
Yes, but the limit is not really a character limit. Search engines measure rendered width, so wide letters and capitals cost more than narrow ones. Aim for 150–160 characters and check how it looks in a preview tool.
What about Chinese text?
Character count is the right measure there, since there are no spaces between words. One Chinese character is one code point but three bytes in UTF-8, so byte-limited systems allow roughly a third of the characters.
Is the text stored anywhere?
No. The count is computed in your browser and the textarea is never sent to a server. Reload the page and the sample text returns.
