String Length Calculator
Count characters, bytes, and length with/without spaces — instantly.
Character limits show up everywhere — tweet length, meta descriptions, database fields — and counting manually is error-prone. This gives an instant, accurate breakdown as you type.
Why character count and byte count can differ
A single character can occupy more than one byte in UTF-8 encoding — emoji and many non-Latin characters (like Chinese or Arabic script) commonly take 2-4 bytes each, so a string with 10 visible characters might be significantly more than 10 bytes, which matters for systems with strict byte-based storage limits rather than character-based ones.
Frequently asked questions
Why would I need the byte count instead of just character count?
Some databases, APIs, and storage systems enforce limits in bytes rather than characters — if your text includes emoji or non-Latin script, the byte count can be substantially higher than the character count, which matters for staying within those limits.
Does this count spaces as characters?
The main character count includes spaces — a separate "without spaces" figure is shown alongside it if you need the count excluding whitespace specifically.
