How is a word counted?

Text is split on whitespace, and any resulting chunk containing at least one letter or digit counts as a word. Hyphenated compounds such as "state-of-the-art" count as one word, matching the behaviour of Microsoft Word and Google Docs.

What is the difference between characters with and without spaces?

The "with spaces" figure counts every character including spaces, tabs and line breaks. The "without spaces" figure excludes all whitespace. Academic and publishing guidelines usually specify which one they mean, so both are shown.

How is reading time calculated?

Reading time uses 225 words per minute, the accepted average for silent reading of general prose. Speaking time uses 130 words per minute, a comfortable presentation pace. Both are estimates — technical material reads more slowly.

What is keyword density and what is a good percentage?

Keyword density is how often a term appears as a share of total words. For SEO, a natural range for a primary keyword is roughly 0.5% to 2%. Anything higher risks reading as keyword stuffing, which search engines actively discourage.

Can I use this to check a Twitter or meta description limit?

Yes. Watch the "characters with spaces" figure: X/Twitter allows 280 characters, a meta description is best kept near 155, and a page title around 60. The counter updates live so you can trim precisely to the limit.

Is my text sent anywhere or used for training?

No. There are no server calls and no analytics on what you type. All counting happens in JavaScript inside your own tab. The only thing that persists is an auto-saved draft kept in your browser's local storage on this device, so a reload does not lose your work — it is never transmitted, and pressing Clear deletes it.

What is the readability score?

It is the Flesch Reading Ease formula, which combines average sentence length with average syllables per word to give a 0–100 score: 90+ is very easy, 60–69 is plain English, and below 30 reads at a university-graduate level. The grade level beside it is Flesch-Kincaid, which expresses the same idea as a US school year. Both need at least ten words and one full sentence to be meaningful.

How do I lower my reading level?

The formula rewards two things: shorter sentences and shorter words. Splitting a long sentence in two usually moves the score more than any word swap. Replacing multi-syllable words with everyday ones ("use" for "utilise") does the rest. Most web writing aims for 60–70, which is roughly an 8th to 9th-grade level.

Why check two and three-word phrases instead of single keywords?

Real search queries are usually phrases, not single words. Seeing that "content marketing" appears eight times tells you far more about what a page is about than counting "content" and "marketing" separately. Phrases that appear only once are hidden, because a single occurrence is not a pattern.

What do stop words mean in the density table?

Stop words are the structural filler of English — "the", "is", "of", "and". They are always the most frequent words in any text, so leaving them in buries the terms you actually care about. With the filter on, single stop words are hidden, and phrases are dropped only when they start or end with one, which keeps genuine phrases like "machine learning" intact.

Does it count words in languages without spaces?

Languages such as Chinese and Japanese do not separate words with spaces, so the word count will be inaccurate for them. The character count remains correct and is the more meaningful measure for those scripts.

常见问题解答 (FAQ)

Everything people ask about the Word Counter.

词数是如何计算的？

文本依据空格及标点切分。包含字母、汉字或数字的每个语素均会计为一个有效词。

含空格与不含空格的字符数有何区别？

含空格计算所有按键与换行符；不含空格则只计算汉字、字母、数字及标点符号本身。

阅读时长是如何估算的？

按照成年人平均默读速度（英文约 225 词/分钟，中文约 400-500 字/分钟）进行科学折算。

什么是关键词密度？

某个词在全文总词数中的出现百分比。通常 1% 到 2% 是最利于 SEO 的黄金比例。

可以用来检查社交平台的字数限制吗？

可以。通过字符计数器对照：X/Twitter 280 字符、Meta Description 约 155 字符、SEO 标题 60 字符。

我的文本会被保存在服务器上吗？

不会。完全在本地运行。草稿保存在您本地浏览器中，点击“清空”即可彻底抹除。

可读性得分代表什么？

基于 Flesch Reading Ease 经典公式，在 0 到 100 分之间评估词句长度与通俗度。

演讲时长是如何估算的？

按照标准演讲与报告语速（约 130 词/分钟或 250 字/分钟）计算。

支持超长文本的处理吗？
