What is Word Counter?
How It Works
The tool listens for every keystroke in the text area and runs analysis functions on each change. Words are counted by splitting the text using a regular expression that identifies word boundaries โ this correctly handles multiple spaces, newlines, and punctuation. Characters are counted using the string length property. Sentences are identified by periods, question marks, and exclamation marks that are followed by a space or end of text. Paragraphs are counted by finding double-newline breaks in the text.
Formula
Words = text.trim().split(/s+/).filter(w => w.length > 0).length Characters = text.length Characters (no spaces) = text.replace(/s/g, '').length Sentences = text.split(/[.!?]+/).filter(s => s.trim().length > 0).length Reading time (min) = Math.ceil(words / 200) Speaking time (min) = Math.ceil(words / 130)
Formula Explained
The word counting formula trims the text first (removing leading/trailing whitespace), then splits on any whitespace sequence (s+ matches one or more spaces, tabs, or newlines). The filter removes empty strings that can result from multiple consecutive spaces. Character count is simply the total string length in JavaScript. Reading time is calculated assuming the average adult reads 200 words per minute silently, while speaking time uses 130 words per minute โ the typical pace for clear, well-paced speech.
Example
Text: "The quick brown fox jumps over the lazy dog. It was a sunny afternoon." Words: 14 Characters (with spaces): 71 Characters (no spaces): 59 Sentences: 2 Paragraphs: 1 Reading time: 1 minute (rounds up) Speaking time: 1 minute Twitter limit: 71 / 280 characters โ OK โ Meta description: 71 / 160 characters โ OK โ
