Character Counter

How to use the character counter

1. Type or paste your text. The character count updates as you go — there is no Submit button.
2. Read characters with spaces first. That is the number most platforms use.
3. Compare characters without spaces when a form or brief asks for that.
4. Tap X, SMS, Instagram, or Custom if you need remaining characters against a writing limit.
5. Review remaining, close-to-limit, or over. Those labels are in text, not only color.
6. Copy the text or the statistics. Clear asks first if the draft is long.

What counts as a character?

The headline number is a grapheme cluster count (Unicode TR#29 via Intl.Segmenter). A letter, a digit, punctuation, a space, a line break, a precomposed é, and most emoji each count as one visible character. A family emoji built with zero-width joiners still counts as one visible character here, even though it is several code points and more than two UTF-16 units.

That is why this page does not use JavaScript string.length as the main figure. string.length is UTF-16 units. UTF-8 bytes are shown separately because storage size is not the same as “how long does this look.”

Characters with and without spaces

With spaces includes every visible character plus Unicode whitespace: spaces, tabs, and newlines. Without spaces drops those whitespace graphemes and keeps letters, digits, punctuation, and emoji. “Hello world” is 11 and 10. Use with spaces for X, Instagram, LinkedIn, SMS, and most HTML maxlength fields.

Character count vs word count

Character count is length. Word count is how many whitespace-separated tokens you typed. Different apps can tokenize words differently (hyphens, CJK, contractions). This page does not try to rank for word-counter searches — that job belongs on the Word Counter.

Characters vs UTF-8 bytes

Characters ≠ bytes. A Latin letter is usually one byte. Accented letters and emoji usually take more. Use the headline character count for compose boxes and maxlength. Use UTF-8 bytes when a database column, API, or file-size limit is measured in bytes.

Character limit checker

Presets are writing checks from documented field sizes: X 280 (standard free post), SMS 160 / 70, Instagram caption 2,200 (Graph API), Instagram bio 150, LinkedIn post 3,000 (commonly documented), YouTube title 100 and description 5,000 (YouTube Help). SEO title (~60) and meta description (~155) are not Google hard maximums — snippets vary by device and rewrite. X may count a URL as 23 weighted units. TikTok is omitted because public caption figures conflict.

When people use a character counter

• Social drafts — check an X post, Instagram caption, or LinkedIn update before pasting into the app.
• SEO writing — measure a title or meta description against a writing target, not a Google hard max.
• Students and applications — stay inside a stated character cap.
• Forms and developers — match an HTML maxlength or field constraint.
• SMS — see whether Latin text still fits one 160-character segment before Unicode drops it to 70.

Common character-counting mistakes

• Treating characters as words. Length and token count are different jobs.
• Using “without spaces” for an X or SMS draft. Those fields count spaces.
• Assuming every emoji is one unit in every system. Visible count here is one grapheme; X and SMS can differ.
• Treating ~155 as a guaranteed Google snippet. It is a writing target.
• Confusing characters with UTF-8 bytes. Bytes are for size, not for most compose boxes.
• Pasting from Word and wondering why the count jumped — hidden spaces and curly punctuation still count.
