Readability Guide
What Is a Good Average Sentence Length?
Average sentence length is the single most important factor in readability scoring. For general web content in 2026, aim for 15–20 words per sentence. Here is the complete reference scale.

Pro tip: The secret to engaging writing is variety. Mix short, punchy sentences with longer detailed ones. A consistent sentence length — even a good one — creates monotony. Aim for an average of 15–20 words, not a maximum.
Frequently Asked Questions
Sentence Counter — FAQs
Everything you need to know about how this free online sentence counter works.
How does the sentence counter detect sentences?
The counter scans your text for sentence-ending punctuation: periods (.), exclamation marks (!), and question marks (?). It is smart enough to skip periods that are not sentence endings — such as those in URLs (sentencecounter.blog), decimal numbers (3.14), common abbreviations (Dr., Mrs., etc.), and initials (J.S., U.S.A.). This keeps the count accurate across all types of content.
Is this sentence counter completely free?
Yes, completely. There are no word limits, no character limits, no subscriptions, and no account required. Every feature — sentence count, word count, character count, readability score, reading time, speaking time, and text filters — is 100% free for everyone.
Does it also count words and characters?
Yes. Along with the sentence count, the tool gives you total words, total characters (with spaces), total letters (without spaces), paragraph count, average sentence length, average word length, reading time (at 200 words per minute), and speaking time (at 130 words per minute) — all updating live as you type.
How many sentences is 500 words?
A 500-word text typically contains between 28 and 40 sentences, assuming an average sentence length of 13–18 words. This is the standard range for a well-structured blog introduction or short essay. Paste your 500-word text into the counter above to get your exact number instantly.
How many sentences is 1000 words?
A 1,000-word article typically contains between 55 and 70 sentences at an average sentence length of 15–18 words per sentence. For academic writing running slightly longer at 18–22 words per sentence, expect 45–55 sentences in 1,000 words.
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.
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 does not create a new paragraph. This matches how paragraphs work in most word processors, text editors, and HTML documents.
Is my text kept private?
Yes. Everything happens entirely 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 is gone. It is completely safe to use with personal writing, work documents, confidential reports, or anything else you would rather keep private.
Does this work on mobile phones and tablets?
Absolutely. The tool is fully responsive and works perfectly on all mobile devices. The layout adjusts automatically for smaller screens, so you get the same complete sentence count breakdown whether you are on a phone, tablet, or desktop computer.
Does the sentence counter work for languages other than English?
Yes, it works reliably for any language that uses standard punctuation marks (. ! ?) to end sentences — which covers most Latin-script languages including Spanish, French, German, Italian, Portuguese, and Urdu in Roman script. Languages that use different sentence boundary conventions (such as Arabic full stop ۔ or Chinese 。) may not be counted as accurately.
How do I count sentences in a PDF?
Open the PDF in any PDF viewer (Adobe Acrobat, Chrome, or Preview on Mac). Press Ctrl+A to select all text, then Ctrl+C to copy it. Paste the copied text into the box above with Ctrl+V. The sentence count will appear instantly. For scanned PDFs (images), use a free OCR tool first to extract the text, then paste it here.
What is the best sentence length for SEO in 2026?
For general blog content targeting a broad audience in 2026, the ideal average sentence length is 15–20 words per sentence. Content averaging below 15 words per sentence scores as "Easy to read" and performs better with general audiences on Google. Sentences averaging above 25 words are considered "Hard to read" and can increase bounce rates, which negatively affects Google rankings.
