Character Counter Online
Count characters (with and without spaces), words, sentences, and paragraphs instantly. Free, no signup — perfect for Twitter, Instagram, SMS, and meta tags.
Platform character limits vary more than most people expect, and exceeding them has real consequences. Twitter/X allows 280 characters per post, but counts most emoji as 2 code points and complex sequences — flags, family emoji — as 4 or more, so text that measures 278 in a standard counter may still overflow the compose box. SMS adds a different wrinkle: standard GSM-7 encoding fits 160 characters per segment, but the moment any character falls outside the GSM-7 alphabet — a curly apostrophe, an em dash, or an emoji — the entire message switches to UCS-2 encoding and the per-segment limit drops to 70 characters, which can double your carrier billing with no visible warning.
SEO has its own character arithmetic. Google's title tag display is measured in pixel width, not character count — "WWW" is about three times wider than "iii" — so the practical cutoff for mixed-case English is roughly 50–60 characters. Meta descriptions truncate at around 155 characters in desktop results and shorter on mobile. Staying under 155 keeps your intended summary visible rather than letting Google substitute its own.
Beyond social and SEO, database columns are commonly constrained to VARCHAR(255) or VARCHAR(500), and form validation enforces those limits server-side. The word counter adds per-paragraph reading-time estimates alongside the character breakdown.

Frequently asked questions
Does character count include spaces?
Most platforms count spaces as characters. The "Characters" stat above includes spaces. Use "Characters (no spaces)" if you need the count without whitespace — useful for comparing text density or meeting certain publishing requirements.
How many characters is 1 KB of text?
Plain ASCII text uses 1 byte per character, so 1 KB = approximately 1,000 characters. Unicode/UTF-8 characters (emoji, accented letters, Chinese characters) can use 2–4 bytes each, so 1 KB of Unicode text contains fewer characters.
How do I count characters for an SEO meta description?
Paste your meta description into the box above and check the "Characters" count. Google displays approximately 150–160 characters in search results — descriptions longer than that get cut off. Keep your most important information in the first 150 characters.
Does this count emoji as one character?
Emoji count as 1 character in our counter (JavaScript string length). However, Twitter/X counts most emoji as 2 characters, and some complex emoji sequences (flags, family emoji) count as even more. Always verify Twitter character counts in the Twitter compose box.
Can I count characters in multiple languages?
Yes — the counter handles all Unicode text. Each character (letter, number, punctuation, emoji) counts as 1 character regardless of language. Chinese, Arabic, Korean, and other non-Latin scripts are fully supported.
How many characters are in a tweet?
Twitter/X allows 280 characters per post. Spaces, punctuation, and most emoji count toward this limit. URLs are shortened to a fixed 23-character t.co link regardless of their actual length. Replies that include @mentions at the start do not count those mentions toward the 280 limit.
How many characters can an Instagram bio be?
Instagram bios are limited to 150 characters. This applies to both personal and business profiles. Paste your bio draft above to check it before updating your profile — keeping it under 150 characters ensures nothing gets cut off on any device.
How many characters should a YouTube title be?
YouTube allows up to 100 characters for video titles, but titles are truncated in search results at around 60–70 characters. Aim for 60–70 characters to ensure your full title is visible in search. Put the most important keywords at the front.
What is the character limit for Facebook posts?
Facebook allows up to 63,206 characters in a post, but posts perform best when kept to 40–80 characters — short posts get significantly more engagement according to Facebook's own data. For ads, the primary text field has a recommended limit of 125 characters before it gets truncated in the feed.
How do I count characters in Excel?
Use the LEN() function. For example, =LEN(A1) returns the number of characters in cell A1 including spaces. To count without spaces, use =LEN(SUBSTITUTE(A1," ","")). For a quick check without opening Excel, paste the text here instead.
What is the difference between bytes and characters?
In ASCII, every character is exactly 1 byte — so 1,000 characters = 1,000 bytes. In Unicode (UTF-8), characters outside the basic Latin alphabet use 2–4 bytes each. Emoji typically use 4 bytes. A 1 KB limit measured in bytes will hold fewer characters if you use emoji or non-Latin scripts.
How many characters is a 500-word essay?
A 500-word essay contains approximately 2,500–3,000 characters including spaces, or roughly 2,000–2,500 characters without spaces. The exact count depends on word length — technical writing with long words will be closer to 3,000, while simple text with short words will be closer to 2,500.
