トラブルシューティング

Word count is higher than expected

解決策

The counter splits on whitespace, so hyphenated words (e.g., "well-known") count as one word. Numbers, URLs, and email addresses each count as one word as well.

Reading time seems too short

解決策

Reading time is estimated at approximately 200 words per minute, which is the average silent reading speed for adults. Faster readers may finish sooner; technical content typically takes longer.

Sentence count does not match my expectation

解決策

Sentences are detected by counting periods, exclamation marks, and question marks. Abbreviations (e.g., "Dr.") or ellipses may cause slight overcounting.

よくある質問

単語数は正確ですか?

単語数は非常に正確です。ほとんどのワードプロセッサと同様に、空白で分割してカウントします。

読書時間はどのように計算されますか?

成人の平均読書速度である 1 分間に 200 語をもとに推定されます。

Does it count words in other languages?

Yes, the tool counts words by splitting on whitespace, so it works for any language that uses spaces between words. Languages like Chinese and Japanese that do not use spaces will show accurate character counts but word counts will not be meaningful.

Is there a text length limit?

There is no imposed limit — you can paste very long documents and the statistics will update. Very large texts (hundreds of thousands of words) may cause a brief delay on slower devices.

What counts as a sentence?

Sentences are counted by detecting terminal punctuation (., !, ?). Abbreviations like "Dr." or "e.g." may occasionally be counted as sentence endings, resulting in a slightly higher sentence count than expected.

Can I use this for SEO meta descriptions?

Yes. Meta descriptions are typically 150–160 characters. Use the character count (with spaces) to ensure your meta description falls within this range for optimal search engine display.

Is my text saved or sent to a server?

No. All processing happens entirely in your browser. Your text is never sent to any server, is not stored in any database, and is cleared when you leave the page.

What is the difference between characters with and without spaces?

Characters with spaces counts every character including spaces and newlines. Characters without spaces counts only non-whitespace characters. Publishers and social platforms often specify limits using one or the other.
