Well beyond the comfort zone at CET-4 level. If you want it anyway, start by accepting that you will not follow every sentence.
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 405 of them.
Advanced — read it with glosses. 70,062 words in total; at 150 words a minute for a non-native reader, about 7 h 47 min to finish. Average sentence length 20.1 words. This book is heavy on rare, archaic and invented words: even 25,000 high-frequency word families will not reach 95% coverage — its difficulty is not in the common vocabulary.
The opening of The Prince and the Pauper, 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.
In the ancient city of London, on a certain autumn day in the second quarter of the sixteenth century, a boy was born to a poor family of the name of Canty, who did not want him. On the same day another English child was born to a rich family of the name of Tudor, who did want him. All England wanted him too. England had so longed for him, and hoped for him, and prayed God for him, that, now that he was really come, the people went nearly mad for joy. Mere acquaintances hugged and kissed each other and cried. Everybody took a holiday, and high and low, rich and poor, feasted and danced and sang, and got very mellow; and they kept this up for days and nights together. By day, London was a sight to see, with gay banners waving from every balcony and housetop, and splendid pageants marching along. By night, it was again a sight to see, with its great bonfires at every corner, and its troops of revellers making merry around them. There was no talk in all England but of the new baby, Edward Tudor, Prince of Wales, who lay lapped in silks and satins, unconscious of all this fuss, and not knowing that great lords and ladies were tending him and watching over him--and not caring, either. But there was no talk about the other baby, Tom Canty, lapped in his poor rags, except among the family of paupers whom he had just come to trouble with his presence.

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 measured against the CET-4 ∪ Gaokao lists, so this is difficulty for a Chinese-speaking learner, not a native-child reading level.
