How long until you can read Dostoevsky?
The usual answers are folklore — "two years", "after B2", "a lifetime". Here is what the texts themselves say. We measured every word of fifteen Russian classics, Dostoevsky's «Белые ночи» among them: running words, distinct dictionary words.
The honest arithmetic
Reading research puts comfortable unassisted reading at 95–98% word coverage (Hu & Nation). Against this shelf, that costs:
| Words learned | Coverage of the running text |
|---|---|
| 500 | 67.3% |
| 2000 | 82.8% |
| 5000 | 95.9% |
| 7000 | 98.9% |
So unassisted Dostoevsky is a 5,000–7,000 word project. At a sustainable twenty new words a day, that is roughly a year of steady work — faster than the folklore, slower than the ads.
The shortcut nobody mentions
The 95% threshold is the cost of reading without help. With every word glossed where it stands — tap for the dictionary form, the meaning, the stress — the threshold disappears, and you can be inside «Белые ночи» (16861 words, 1848) long before your vocabulary has caught up. The vocabulary then grows from the reading, in the order the books actually need, which is what the sentence-unlocking word lists are.
