Readability Checker
Is your text as clear as you think? Paste it in, choose the language, and the checker immediately calculates established readability scores for English, German or Italian. It also highlights the places where readers stumble: long sentences, very long words, passive voice, filler words and nominal style.
The analysis runs entirely in your browser. Your text is not transmitted and not stored.
As soon as you enter text, the results appear here.
Readability formulas give indications, not judgements. They measure sentence and word length, not content, structure or audience. Web copy should usually aim for “easy” to “fairly easy”: Flesch score of 60 or more, Vienna formula about 4 to 8, Gulpease 60 or more.
Copy that gets read
Our team writes website copy, blog posts and campaigns that your audience understands and enjoys reading, in English, German and Italian.
How to read the result
The analysis runs live in your browser and updates with every change. At the top you see the key figures, below them your text with coloured highlights and a list of the longest sentences.
- 01
English: Flesch Reading Ease and Flesch-Kincaid
Flesch Reading Ease runs from 0 to 100: the higher the score, the easier the text. Around 60 to 70 suits most websites. The Flesch-Kincaid grade translates the result into a US school grade, so a value of 8 means a text an eighth-grader can follow.
- 02
German and Italian
For German, the checker calculates the Wiener Sachtextformel, developed in Vienna for German non-fiction and expressed as a school grade from 4 to 15, plus the Flesch score adapted by Amstad. For Italian it uses the Gulpease index, designed specifically for Italian and ranging from 0 to 100.
- 03
Text statistics
Words, sentences and average sentence length show how dense your text is. Reading and speaking time help with planning, for example for a blog post, a video or a speech.
- 04
Highlights in the text
Sentences with more than 20 words are highlighted in yellow, those with more than 30 words in red. The checker also marks very long words, passive constructions, filler words such as “actually” or “basically” and nominal style, meaning nouns like “implementation” that hide an action.
- 05
Longest sentences and tips
A list shows the longest sentences in your text so you know where to start. Matching tips explain how to split sentences, turn passive into active voice or change nouns back into verbs.
Why clear texts achieve more
On the web, people rarely read; they skim. Anyone who gets stuck on a convoluted sentence is more likely to leave than to read it a second time. Short sentences and clear words make sure your message gets across even when people scroll quickly.
Clarity is also a question of accessibility. People with reading difficulties, non-native speakers and anyone short on time benefit most from simple texts, and everyone else still prefers reading them.
Search engines and AI assistants favour content that answers a question clearly and directly. A readable text is easier to summarise and quote, and it comes across as more competent, not less.
The formulas provide indications, not judgments. They count syllables and sentence lengths but do not understand content. A specialist text for experts may be more demanding than a product page. Use the scores to compare texts and find stumbling blocks.
