Frequently Asked Questions
How are words counted for Chinese text?
For Chinese text without spaces between characters, each individual Chinese character is counted as one word. For English text, words are split by whitespace. Mixed text is handled intelligently; both methods apply simultaneously.
What is keyword density and why does it matter?
Keyword density shows how often each word appears in your text as a percentage of total words. It helps writers avoid overusing certain terms, maintain natural flow, and optimize content for SEO; a density of 1-3% is a common target for a primary keyword, and going far above 5% reads as keyword stuffing. Common stop words (like 'the', 'and', 'of') are excluded from the analysis.
How is reading time calculated?
Reading time is estimated based on average reading speeds: 238 words per minute for English text and 400 characters per minute for Chinese text. The tool automatically detects the dominant language to use the appropriate speed. Speaking time uses 150 words per minute or 300 characters per minute.
Why does my word counter count spaces as characters?
Because the counter tracks two numbers side by side: total characters including spaces, and characters without spaces. Social media platforms count all characters including spaces, while some academic guidelines exclude them; having both lets you quote the number your target platform actually uses.
How are paragraphs defined?
Paragraphs are separated by one or more blank lines (double newlines). A single line break within a paragraph does not create a new paragraph. This matches standard document formatting conventions.
Why does the word count differ from Microsoft Word?
Word counts words by its own rules (how hyphenated compounds, numbers and CJK text are counted), and it may include or exclude headers, footnotes and text boxes depending on the selection. This tool counts exactly what you paste, treats every Chinese character as one word, and counts all visible text, so the numbers usually differ slightly. Both are correct under different definitions.
Can I count words in a PDF?
Not directly: paste the text instead. Extract the text first: most PDF readers let you select and copy text (for scanned PDFs you need OCR first), then paste it here for the word count plus reading time and keyword analysis.
What's the difference between words and unique words?
'Words' is the total number of words in your text (including repetitions). 'Unique Words' counts each distinct word only once. A higher unique-to-total word ratio indicates greater vocabulary diversity, which often correlates with better writing quality.
Can I use this for social media content?
Yes. The character count with spaces is useful for Twitter/X (280 chars), Facebook posts, SMS messages, and other platforms with length limits. The reading time estimate helps you gauge how long your content takes to consume.
How does the tool count words in different languages?
For English and most European languages, words are split by whitespace. For Chinese, Japanese, and Korean (CJK), each character counts as one word since there are no spaces between words. Mixed content is handled by applying both methods simultaneously. This ensures accurate counts for bilingual or multilingual text.
What is the longest word detection useful for?
The longest word feature helps identify: typos where characters are accidentally merged (common in hurried typing), overly long compound words that may confuse readers, and unusually technical terminology that could be simplified. It's also useful for linguistic analysis and studying vocabulary patterns.
Why does my word counter count citations when I need a count without them?
The counter counts exactly what you paste; it cannot know which sentences are citations. To get a word count without citations, remove the references from the text before counting, or count only the body section if the platform (like a journal form) splits the text. Word's 'exclude footnotes' option only affects footnotes, not in-text citations, and different assignment rubrics count differently; ask which rule your submission needs.
Why does my word counter online slow down with a very long document?
Re-counting on every keystroke over 100,000+ words costs CPU, and extremely large pastes can lag on older devices. This word counter debounces updates so it only re-counts when you pause, which keeps it responsive for normal documents. For a multi-megabyte text, count in sections or use desktop Word; the numbers are identical because the counting rules are the same.
