What Is String Length Calculator?
String Length Calculator is a free string length calculator that measures the number of characters in your text. It shows total characters, characters without spaces, and byte size for quick reference.
Key Features
Instant character count as you type. Shows length with and without spaces. Displays byte size for technical use cases. Handles unicode and multi-byte characters accurately. No text length limits.
Benefits
Quickly verify text fits within character limits. Useful for developers checking string lengths for validation rules. Save time compared to counting characters manually or writing code to check lengths.
Use Cases
Check social media post character limits. Verify database field input lengths. Validate API request parameter sizes. Ensure SMS messages fit within the 160-character limit. Test form input validation rules.
Tips for Best Results
Use the without-spaces count when platforms exclude spaces from limits. For database work, check byte size since unicode characters may use more than one byte. Combine with the Word Counter for complete text metrics.
