Word Count for Mixed Chinese–English Text (Abstract / Submission Limits)

Journal word limits look simple, but miscounts are common because Chinese and English are counted differently:

• English is counted by word: a continuous sequence of letters and digits separated by whitespace counts as one word.
• Chinese is counted by character: each Chinese character counts as one; punctuation is usually excluded.

For a mixed Chinese–English abstract, Word’s “word count” gives the sum of Chinese characters plus English words, while many journal submission systems count raw characters — the two can differ by more than 20%. This tool lists several counting methods side by side so you can use whichever one your target journal specifies.

A few details that are easy to overlook:

• Abstract word limits usually exclude the title, keywords, and references, but include the subheadings of a structured abstract (Background / Methods / Results / Conclusions).
• Whether numbers and units count as words: 5 mg/kg counts as two words (5 and mg/kg) in most systems.
• Hyphenated words: well-characterized is usually counted as one word.
• Chinese journals’ “word count” generally means character count (excluding spaces), punctuation included.

The same sentence, three methods — a 2.6× difference

Try this mixed Chinese–English sentence:

本研究纳入 120 名受试者，随访 12 weeks。The primary endpoint was HbA1c.

The smallest and largest differ by 2.6×. An “abstract not to exceed 250 words” limit means something completely different depending on which method applies. This tool lists all methods in parallel so you can pick the one your target journal specifies — rather than guessing.

Three things to verify before submitting

First, whether the limit is in words or characters. English-language journals almost always use word count; Chinese journals mostly use character count. Mixed-language abstracts are the most error-prone, because the two methods can differ by more than twofold.

Second, which sections count. Abstract limits usually exclude the title, authors, keywords, and references, but include the subheadings of a structured abstract. Body-text limits usually exclude figure captions and references, though this varies considerably between journals.

Third, the submission system’s count is the authoritative one. Being exactly at the limit in Word and then getting flagged as over-limit on upload is common — the two use different algorithms. Leaving a 5% margin is less trouble than cutting it to the exact word.
