Yes. Completely free, no account required, no usage limits.

What is a good Flesch Reading Ease score for a blog or website?

A score of 60–70 is the standard target for most web content — accessible to a broad general audience without feeling overly simplified. Marketing copy and landing pages often aim for 70–80 to maximize readability and conversion. Academic and technical writing typically scores in the 30–50 range.

How is keyword density different from SEO keyword frequency?

WordLens calculates raw keyword frequency: how often each meaningful word appears relative to total word count. SEO keyword density is a narrower concept focused specifically on the frequency of a target search keyword. A density of 1–2% for a target keyword is a commonly cited guideline for on-page SEO, though modern search engines evaluate context rather than raw counts.

Does WordLens work with languages other than English?

WordLens counts characters, words, sentences, and paragraphs for any language. The Flesch Reading Ease score and stop-word filtering are calibrated for English and will not produce meaningful results for other languages. Character counts and word counts are language-agnostic.

How to Use WordLens

WordLens is a real-time text analysis tool that runs entirely in your browser. There is nothing to install, no account to create, and no file to upload. Follow these five steps to get the most out of it.

Open WordLens in your browser. The tool is ready the moment the page loads. No sign-up, no waiting.
Paste or type your text into the input area. You can drop in a full article draft, an email, a social post, an essay — anything from a single sentence to thousands of words.
Watch the six stats update in real time. As you type or paste, the words, characters, characters (no spaces), sentences, paragraphs, and estimated reading time all update automatically. There is no button to press.
Check readability and keywords once you have 10 or more words. Two panels appear below the stats grid: a Flesch Reading Ease score with a colour-coded bar, and a Top Keywords table showing the 10 most frequent meaningful words in your text along with their count and density percentage.
Click ✕ Clear to start a fresh analysis. The button appears in the top-right corner of the input area as soon as you add text. It resets all metrics instantly.

What WordLens Measures

WordLens calculates eight distinct metrics from your text, all processed locally inside your browser — your content is never sent anywhere.

Words — Every whitespace-delimited token counts as one word. Hyphenated compounds (state-of-the-art) and contractions (don't, it's) each count as one word. URLs and email addresses also count as one word each.
Characters — Every character in your text, including spaces, punctuation, and line breaks. This matches the character counter most social platforms display.
Characters (no spaces) — The character count after all whitespace is stripped. Useful for SMS limits and platforms that exclude spaces from their counts.
Sentences — Boundaries detected at periods, exclamation marks, and question marks. The counter handles common abbreviations (Dr., a.m., e.g.) and ellipses without creating false splits.
Paragraphs — Blocks of text separated by one or more blank lines.
Reading Time — Estimated at 225 words per minute, the average adult silent reading speed for general English content.
Flesch Reading Ease — A 0–100 score based on average sentence length and average syllables per word. Scores of 60–70 are the standard target for most web content; higher means easier to read.
Top Keywords — The 10 most frequent meaningful words after common stop words (the, and, is, etc.) are removed, shown with count and density percentage.

Common Use Cases

Checking SEO content length. A blogger drafting a 1,500-word article pastes their draft into WordLens to confirm the word count and verify that the Flesch score sits in the 60–70 "Standard" range before publishing — long enough to rank, readable enough to hold attention.
Verifying essay submissions. A student finishing a 2,000-word university assignment pastes the final draft to get an exact word count, eliminating any risk of a penalty for going under or over the required limit.
Fitting social media copy. A social media manager drafts a LinkedIn post and uses the character counter to trim the copy to under 3,000 characters — LinkedIn's post limit — before switching to the platform to publish.
Auditing documentation readability. A technical writer checks the Flesch score of a developer guide to confirm it reads accessibly to a non-specialist audience, then uses the keyword panel to verify that key technical terms appear at an appropriate frequency.

How WordLens Works

Paste or type any text into the input area above. WordLens instantly analyzes your text as you type — no button to press, no waiting. All processing happens inside your browser using JavaScript. The moment you stop typing, every metric is already calculated.

Because there is no server involved, WordLens works offline once loaded and has no usage limits. Your drafts, documents, and notes remain completely private — nothing you paste into WordLens is ever transmitted anywhere.

What Each Metric Means

Words — Sequences of non-whitespace characters separated by spaces. Hyphenated compounds (state-of-the-art) count as one word. Contractions (don't, it's) count as one word.
Characters — Every character including spaces, punctuation, and line breaks. This is the total character count most social platforms report in their limits.
Characters (no spaces) — Characters after all whitespace is removed. Useful for character-limited platforms that exclude spaces from the count, such as certain SMS providers and Asian-language text fields where spaces are optional.
Sentences — Sequences ending in a period, exclamation mark, or question mark. WordLens handles abbreviations (Dr., a.m., e.g.) and ellipses without incorrectly splitting them into multiple sentences.
Paragraphs — Blocks of text separated by one or more blank lines.
Reading Time — Estimated at 225 words per minute, the average silent reading speed for adults reading general content in English. Academic and technical writing is typically read more slowly.

What Is the Flesch Reading Ease Score?

The Flesch Reading Ease formula measures how easy a passage of English text is to read, based on average sentence length and average word length (in syllables). The result is a score from 0 to 100:

Score	Difficulty	Typical Audience
90–100	Very easy	5th grade
70–90	Easy	6th grade
60–70	Standard	7th–8th grade
50–60	Fairly difficult	High school
30–50	Difficult	College level
0–30	Very difficult	Academic / legal

A score of 60–70 is the sweet spot for most web content — readable by a broad audience without feeling dumbed down. Marketing copy, product descriptions, and blog posts typically perform best in the 65–80 range. Legal documents and academic papers often score below 30, which is appropriate for their audience but would be unsuitable for a general readership.

The two primary levers for improving your Flesch score are sentence length and word complexity. Long sentences with many clauses drag the score down, as do polysyllabic words where shorter alternatives exist. Breaking a 40-word sentence into two 20-word sentences and replacing "utilization" with "use" can move a passage from "Difficult" to "Standard" without changing its meaning.

Who Uses WordLens?

A word counter sounds simple, but the need for one comes up in more situations than most people expect.

Bloggers and content writers — Meeting a minimum word count for SEO or a maximum length for editorial guidelines. Checking that an article is long enough to rank well in search, or short enough to hold a reader's attention without padding.
Students — Verifying that an essay or assignment meets word count requirements. Many universities specify minimums and maximums, and being off by more than 10% can result in a penalty. Pasting a draft into WordLens takes two seconds and gives an exact count before submission.
SEO writers and digital marketers — Monitoring keyword density to ensure a target keyword appears often enough to signal relevance without triggering over-optimization penalties. Checking readability scores to ensure copy is accessible to a general audience.
Social media managers — Drafting posts within platform character limits. Twitter (X) allows 280 characters; LinkedIn posts perform best around 1,300 characters; Instagram captions are capped at 2,200 characters. WordLens gives real-time character counts so you can edit to fit before switching to the platform.
Journalists and editors — Measuring article length to fit column inches or publication word limits. Checking readability to ensure a piece is pitched at the right level for its audience.
Developers writing documentation — Technical writers and developers drafting README files, API documentation, or help articles use word count to gauge whether a section is too long and needs to be split, and readability scores to check whether a guide is accessible to its intended audience.

Word and Character Limits by Platform

Different platforms impose different limits on text length. Use WordLens to check your content against these limits before you publish.

Platform / Context	Limit type	Limit
Twitter / X (standard post)	Characters	280
Twitter / X (Premium)	Characters	25,000
LinkedIn post	Characters	3,000
LinkedIn article	Characters	125,000
Instagram caption	Characters	2,200
Facebook post	Characters	63,206
YouTube description	Characters	5,000
Meta (Google Ads) title	Characters	30
Meta (Google Ads) description	Characters	90
Email subject line (recommended)	Characters	40–60
SMS message (single segment)	Characters	160
Typical blog post (short)	Words	600–1,000
Typical blog post (SEO-optimized)	Words	1,500–2,500
University essay (undergraduate)	Words	1,000–3,000

Note: platform limits can change over time. The figures above reflect commonly reported limits as of 2025–2026.

Tips for Improving Your Readability Score

If your Flesch score is lower than you'd like, the following adjustments typically have the most impact:

Shorten your sentences. The average sentence length is the most powerful lever in the Flesch formula. Aim for an average of 15–20 words per sentence in general web content. Any sentence longer than 35 words should be reviewed for splitting.
Replace long words with shorter alternatives. "Use" instead of "utilize." "Show" instead of "demonstrate." "Start" instead of "commence." Every syllable reduction improves your score.
Prefer active voice over passive voice. "The team completed the report" (active) reads more clearly than "The report was completed by the team" (passive) — and is shorter.
Break up dense paragraphs. Although paragraph length does not directly factor into the Flesch formula, long blocks of text create visual density that discourages reading. Three to five sentences per paragraph is a common guideline for web content.
Use subheadings and lists. Subheadings allow readers to scan, which reduces the cognitive load even before they begin reading. Lists break multi-step or multi-item content into digestible pieces.

Frequently Asked Questions

Is my text sent to a server?

No. WordLens runs entirely in your browser. Nothing you type or paste is transmitted anywhere. The tool has no server to send data to.

How is reading time calculated?

At 225 words per minute — the average adult silent reading speed for general content. Short texts under 225 words show "< 1 min".

How does keyword density work?

WordLens counts every word, removes common stop words (the, and, is, etc.), and displays the top 10 most frequent words with their count and percentage of total words.

Is WordLens free?

Yes. Completely free, no account, no limits.

What is a good word count for a blog post?

For general informational content, 600–1,000 words is sufficient. For content targeting competitive search keywords, most SEO research suggests 1,500–2,500 words tends to correlate with higher rankings — though quality and relevance matter more than length alone. Opinion pieces, news updates, and quick tutorials can be effective at 400–600 words if they fully answer the reader's question.

What is a good Flesch Reading Ease score for web content?

A score of 60–70 is the standard recommendation for general web content. Marketing copy, landing pages, and product descriptions often target 70–80 for maximum accessibility. News articles typically fall in the 60–70 range. Academic papers and legal documents routinely score below 30, which is appropriate for a specialist audience but unsuitable for a general readership.

Does WordLens support languages other than English?

Character counts, word counts, sentence counts, and paragraph counts work for any language. The Flesch Reading Ease score and the stop-word filtering in the keyword density section are calibrated for English only and will not produce meaningful results for other languages.

How is keyword density calculated?

WordLens counts every word in your text, strips common English stop words (articles, prepositions, conjunctions), and calculates each remaining word's frequency as a percentage of total word count. For SEO purposes, a target keyword density of 1–2% is a commonly cited guideline, though modern search engines evaluate topical relevance rather than raw keyword counts.

Can I use WordLens to check my Twitter or LinkedIn post length?

Yes. Paste your draft into WordLens and watch the character count update in real time. Twitter's standard limit is 280 characters; LinkedIn posts are capped at 3,000 characters. The "Characters" stat in WordLens matches the character count most platforms use.
