Reads steadily at a 5,000-word vocabulary. An unknown word here and there, usually carried by the sentence around it.
Coverage = the share of words in the text you already know. The research gives two lines: 98% before independent fluent reading is realistic, 95% for the instructional level that needs support (Hu & Nation, 2000). Proper nouns are not counted as unknown — recognising that it is a name is enough; this book has 264 of them.
Finishable at 5,000 words, with the odd lookup. 160,554 words in total; at 150 words a minute for a non-native reader, about 17 h 50 min to finish. Average sentence length 17.3 words. Reaching 95% coverage on this book (the floor for readability) takes roughly 7,500 word families.
The opening of Emma, word for word. Tap any word you don't know and its meaning here appears beside it — no sign-up, tap as often as you like.
Emma Woodhouse, handsome, clever, and rich, with a comfortable home and happy disposition, seemed to unite some of the best blessings of existence; and had lived nearly twenty-one years in the world with very little to distress or vex her.
She was the youngest of the two daughters of a most affectionate, indulgent father; and had, in consequence of her sister’s marriage, been mistress of his house from a very early period. Her mother had died too long ago for her to have more than an indistinct remembrance of her caresses; and her place had been supplied by an excellent woman as governess, who had fallen little short of a mother in affection.

Readii cuts this book into three-minute passages. Tap a word you don't know and its meaning in that exact sentence appears in place — no jumping out, no losing the thread.
The opening chapters are free — no account, no card.
Ordered by unknown words per 100. Lower reads easier; to step up a level, pick a higher number.
Computed by Readii from the public-domain text (updated 2026-10-21), not estimated by hand. The Readii reading level is our own scale, anchored on unknown-word density; it is not the same system as Lexile or AR and does not convert directly. Unknown words are counted against a frequency list built from a large subtitle corpus, so the bands mean the same thing for any learner of English, whatever your first language. This is difficulty for a non-native reader, not a native-child reading level.
