Free Online Sentence Counter (Sentences, Words, & Characters)

How is a sentence count produced?

This sentence counter scans your text for sentence-ending punctuation such as periods, exclamation marks, and question marks. It will then quickly count each resulting sentence. The tool is smart enough to skip over periods that aren't sentence endings, like those found in URLs (www.textfixer.com), decimal numbers (3.14), common abbreviations (Dr., Mrs., etc.), and initials (J.S., U.S.A.). This keeps the count fairly accurate across all types of content.

Why would I need a sentences count?

Sentence counts are more useful than most people realise. Teachers use them to assess writing complexity and development. Editors use them to check pacing and readability. Content writers use them to make sure they're not writing walls of text that push readers away. If you're optimising content for readability scores like Flesch-Kincaid, sentence count is one of the core inputs.

Does it also count words and characters?

Yes, indeed. It counts sentences plus words, and characters (with and without spaces included). Plus it gives you average sentence length in words and average word length plus a reading time estimate. What more could you ask for?

What's a good average sentence length?

For general web content, you should aim for an average of 15 to 20 words per sentence. Academic writing typically runs longer, while conversational copy tends to be shorter. The key to most engaing content is to have a mix. A mix of short and longer sentences keeps things punchy. If the majority of your sentences are running past 25–30 words, that's usually a sign something should be split up.

Does the tool count sentences in different languages?

It works reliably with any language that uses standard punctuation marks (. ! ?) to end sentences, which covers most Latin-script languages. Languages that use different sentence boundary conventions wil not be counted as accurately.

What counts as a paragraph?

Paragraphs are counted as blocks of text separated by a blank line (a double line break). A single line break on its own doesn't create a new paragraph. This matches how paragraphs work in most word processors and text editors.

How is reading time calculated?

Reading time is based on an average silent reading speed of 200 words per minute, which is a widely used benchmark for adult readers. Speaking time uses 130 words per minute, reflecting a natural conversational pace. Both are estimates. Actual times vary depending on the complexity of the content and the individual reader.

Is my text kept private?

Yes. Everything happens directly in your browser. Your text is never sent to a server, never stored, and never logged. The moment you close or refresh the page, it's gone. It's safe to use with personal writing, work documents, or anything else you'd rather keep to yourself.

Does this work on phones and tablets?

Absolutely. The tool is fully responsive and works well on mobile devices. The layout adjusts automatically for smaller screens, so you get the same full breakdown whether you're on a phone, tablet, or desktop.

Is this really a free online sentence counter ?

Yes, like the rest of the tools on this website, this sentence counter is completely free and requires no account or registration to use.
