Swedish text difficulty checker
Paste any Swedish text here and Beeblio will tell you, word by word, how difficult it is for you right now. Every word in your text is matched against frequency ranks drawn from the wordfreq corpus and sorted into bands: the 300 most common Swedish words, the 800 most common, up to 12,000 and beyond. Because the ~1,500 most frequent words cover around 80% of everyday Swedish text, the tool gives you a fast, honest picture of how much of a newspaper article, song lyric, or short story is already within reach.
The results show the share of words that fall into each frequency band, a list of words you are unlikely to know yet, and the genuinely rare vocabulary that even advanced learners might want to look up. No sign-up is needed — just paste and go.
Use the difficulty checker to choose reading material at the right level, spot the handful of new words worth studying before you read, or track your progress over time by watching the rare-word percentage shrink as your Swedish improves.
How it works
Paste a text in Swedish (up to 6,000 characters). Every word is looked up in a frequency list; for each band — the top 300, 800, 1,500, 3,000, 5,000, 8,000 and 12,000 words — you see the share of the text a learner at that band already knows. Comprehensible reading sits around 95–98% known: we call ≥97% easy, 92–97% just right, 85–92% hard, and below that too hard.
You also get the new words worth learning (unknown but common, in frequency order) and the rare words — names, jargon, typos — that no learner should stop for.
Questions
What do the frequency bands actually mean?
Each band groups words by how commonly they appear in real Swedish text, ranked using the wordfreq corpus. The bands are set at 300, 800, 1,500, 3,000, 5,000, 8,000, and 12,000 words, so a word in the 300 band is one of the most common words in the language, while a word beyond 12,000 is genuinely rare.
How difficult should a text be for it to be good reading practice?
A commonly used guideline is that you should understand roughly 95–98% of the running words in a text for reading to feel manageable and for new vocabulary to stick from context. If Beeblio shows that a large share of your text falls outside your current bands, the text may be better saved for later — or used with a dictionary close at hand.
Does the checker handle Swedish word forms like inflections and compound words?
Yes. Beeblio looks up each word form against the wordfreq frequency data, which is built from real Swedish text and naturally includes common inflected forms such as plurals and verb conjugations. Very long or unusual compound words may occasionally be treated as rare even if their parts are common, since compounds are often unique to a specific context.
