Writers, editors, and translators working in Chinese often need to know how long a passage is — both how many paragraphs it contains and roughly how many printed pages it will fill. This tool counts paragraphs and Chinese characters and turns the character count into a page estimate using the standard book convention.
How it works
Paragraphs are detected by splitting the text on blank lines: any run of one or more empty lines marks a paragraph boundary. A single newline inside a block is treated as a soft line break, so wrapped lines do not inflate the count.
For the character total, only CJK ideographs are counted — the same 字数 (character count) figure Chinese publishers use. Latin words, digits, and punctuation are ignored for the page math. The page estimate is simply:
pages = chinese_characters / 500500 characters per page is the traditional typeset-book figure for Chinese.
Why 500 characters per page?
The 500-character-per-page convention reflects typical Chinese book typography: a 32-open format (32开) paperback set in a common size and leading, with margins, produces roughly 500 Chinese characters per page. It has been used for decades as the standard unit in:
- Publishing contracts — word-count milestones and per-character royalties are defined in terms of 字数 (Chinese character count).
- Literary competitions — submission limits like “maximum 5,000 characters” use this count exclusively.
- Translation pricing — Chinese translation is quoted per hundred or per thousand source or target Chinese characters, not per English word.
- Academic regulations — undergraduate theses in China typically specify a minimum character count (e.g. 8,000 or 10,000 字) rather than a page limit.
For actual layout, a larger trim size with smaller type might fit 600–700 characters, while a children’s book with big type might only fit 200. The 500 figure is a planning norm, not a physical guarantee.
Mixed Chinese–English documents
Because the page estimate counts only CJK ideographs, a document that mixes Chinese and English will show a lower page count than a visual layout would give. For example, a page with two paragraphs in Chinese and two in English might show only 250 characters — suggesting half a page by the formula. In Chinese publishing practice, Latin text is simply not part of the 字数 total that fees, quotas, and length limits are based on, so the separate paragraph count is useful alongside the page estimate to understand the true structure of the document.
Practical guidance
Use the paragraph count to check structural balance in long documents: a chapter that contains 30 very short paragraphs or 3 very long ones is usually a readability signal worth addressing. Pair it with the sentence-length distribution tool if you also want to examine sentence-level pacing within each paragraph.
