Count String Length for Development
Check string lengths, byte sizes, and Unicode character counts for database column sizing and validation.
Development tips
Database VARCHAR columns have byte limits. Use the "Bytes (UTF-8)" stat to check if a string fits in a VARCHAR(255) column — not just character count.
VARCHAR(255) stores up to 255 bytes in MySQL. An emoji (4 bytes) or accented character (2 bytes) takes more space than an ASCII letter (1 byte).
JavaScript's string.length counts UTF-16 code units, not Unicode code points. An emoji returns length 2 in JS but 1 in this tool (code point count).
Check unique character count for password strength analysis or to estimate entropy of user-generated input strings.
