Real-time word counter, character statistics, sentence analysis, and reading time. Includes instant limit checkers for Twitter, LinkedIn, Instagram, Google SEO & College Essays.
Word count is determined by parsing sequences of alphanumeric unicode characters separated by whitespace or punctuation. Characters with spaces include all letters, numbers, symbols, tabs, and line breaks.
Standard Benchmarks: Average adult reading speed is 200–250 words per minute (wpm). Average speaking speed for presentations and speeches is 130–150 wpm.
