5–8 unknown words per 100 at CET-4 level. Looking each one up will stall you; this one wants glosses that appear in place.
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 551 of them.
CET-6 and up, or read it with glosses. 157,059 words in total; at 150 words a minute for a non-native reader, about 17 h 27 min to finish. Average sentence length 12 words — short sentences, brisk pace. Reaching 95% coverage on this book (the floor for readability) takes roughly 14,750 word families.
The opening of Sister Carrie: A Novel, 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.
When Caroline Meeber boarded the afternoon train for Chicago, her total outfit consisted of a small trunk, a cheap imitation alligator-skin satchel, a small lunch in a paper box, and a yellow leather snap purse, containing her ticket, a scrap of paper with her sister’s address in Van Buren Street, and four dollars in money. It was in August, 1889. She was eighteen years of age, bright, timid, and full of the illusions of ignorance and youth. Whatever touch of regret at parting characterised her thoughts, it was certainly not for advantages now being given up. A gush of tears at her mother’s farewell kiss, a touch in her throat when the cars clacked by the flour mill where her father worked by the day, a pathetic sigh as the familiar green environs of the village passed in review, and the threads which bound her so lightly to girlhood and home were irretrievably broken.

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.
