Text Analyzer - Word Count, Character Count & Read Time Tool
Whether drafting SEO blog posts, respecting database VARCHAR byte limits, or adhering to social media character caps, precise text metrics are vital. Simple word counts in word processors often fail to measure multi-byte UTF-8 bytes or omit whitespace distinctions. This Text Analyzer evaluates your copy in real time across characters, words, lines, byte footprints, and keyword densities.
When to Use This Tool
- Database VARCHAR Byte Limits: Ensure strings fit within MySQL or Oracle VARCHAR(255) byte constraints, accounting for UTF-8.
- SEO Title & Meta Description Checks: Optimize titles (50-60 characters) and descriptions (150-160 characters) for Google search snippets.
- Blog & Article Read Time: Estimate audience reading time based on standard reading velocities (200 words/min).
- Essay & Resume Character Caps: Meet strict academic or job application character thresholds (with and without whitespace).
How to Use
- Input Copy: Paste or type your text directly into the main writing area.
- Instant Metric Overview: Review total characters, characters excluding spaces, words, lines, and paragraphs.
- Inspect UTF-8 Byte Size: Check the exact binary byte size (ASCII=1 byte, Korean/Japanese=3 bytes, Emojis=4 bytes).
- Explore Keyword Density: Inspect the most frequently occurring terms to optimize keyword distribution.

Frequently Asked Questions (FAQ)
Q. How is UTF-8 byte size calculated?
A. Standard ASCII letters count as 1 byte. Extended Latin and Greek take 2 bytes. CJK characters (Korean, Chinese, Japanese) take 3 bytes. Modern emojis take 4 bytes. This tool uses standard TextEncoder API for exact byte calculations.
Q. What formula is used for reading time?
A. Reading time is calculated using an average reading speed of 200 to 250 words per minute for English, and approximately 500 characters per minute for CJK scripts.
Q. Is my text uploaded to any external server?
A. No. All calculations are executed purely in your browser runtime via native JavaScript APIs. Your drafts remain entirely private.
