Knowing exact string length is fundamental for database management, SEO, content creation, and API integration. A VARCHAR(100) column truncates at character 101. An API rejects oversized requests. A truncated meta description looks unprofessional.
Measures exact character count including spaces, punctuation, and Unicode. Provides multiple metrics: total characters, characters without spaces, word count, byte length, and line count.
Instant character count with and without spaces, byte length for UTF-8, word and line counts, handles all Unicode including emoji, real-time calculation.
Examines each character using Unicode-aware iteration, counting code points (not UTF-16 code units). For byte length, encodes using UTF-8 rules: 1 byte ASCII, 2 bytes Latin extensions, 3 bytes CJK, 4 bytes emoji.
Database developers check VARCHAR limits. SEO specialists verify meta tags. Social media managers check character limits. API developers validate payload sizes. SMS marketers verify message lengths.
Character counting has edge cases: an emoji might be 7 code points. A Chinese character is 1 char but 3 bytes. Windows line breaks are 2 characters. This tool handles all cases correctly.
Software developers, database administrators, SEO specialists, content creators, API developers, and QA engineers.
Type or paste text. Character count, byte length, word count, and line count appear immediately.
Check both character count and byte length for databases. Keep SEO titles under 55 characters for pixel-width safety. Test boundary conditions with emoji and Unicode.
JavaScript .length and Unicode character count differ for supplementary plane characters. Byte length shown is UTF-8 — your system may use different encoding.
Characters count regardless of byte size. In UTF-8, ASCII uses 1 byte, emoji use 3-4 bytes. 'Hello' is 5 chars/5 bytes. '你好' is 2 chars/6 bytes.
Yes. Shows both with-spaces and without-spaces counts since most systems count spaces.
Simple emoji count as one character but may be 2 UTF-16 code units. Complex emoji like family sequences are multiple code points joined by zero-width joiners.
VARCHAR columns have character limits. Inserting longer strings causes truncation or errors. Checking length prevents both.
Twitter/X allows 280 characters. URLs are shortened to 23 characters regardless of original length.
Google displays first 50-60 characters. This tool verifies your copy fits without truncation.
Yes. Line breaks are 1 character (LF) or 2 characters (CRLF). This matters for strict limits.
Yes. Verify expected counts against actual lengths, especially for Unicode, emoji, and edge cases.
