It depends on what you want to read. Unsimplified novels need a lot: Paul Nation's research on English puts 98% coverage of novels at 8,000–9,000 word families. Stories written for learners need far fewer. Contos moves readers up a level at 500 known words (A2), 1,500 (B1) and 4,000 (B2).

What counts as a word in Spanish?
Word counts look precise, but they depend on what you count. There are three common units:
- Word form: every spelling counts separately, so hablo, hablas and habla are three.
- Lemma: the dictionary form plus its inflections, so all forms of hablar count as one.
- Word family: a lemma plus related words, so hablar, hablador and habladuría might count as one.
Research usually counts families. Spanish verbs make the difference large: a single verb has dozens of forms. Contos counts the forms you know, because that is what you actually meet on the page, so its 500-word step to A2 is a stricter target than 500 families would be.
How many words do you need for each level?
The best-known estimates come from Paul Nation's 2006 study of English. Assuming you need to know 98% of the running words to read without help, he found that novels need a vocabulary of 8,000–9,000 word families and newspapers around 8,000 plus proper nouns, while spoken English needs 6,000–7,000. In his five novels, the most common 2,000 families covered only about 88% of the text. These are English figures, so treat them as a rough guide for Spanish; the extensive reading page explains where the 98% figure comes from and why it is debated.
Learner stories need much less, and the Contos library shows how vocabulary builds level by level. For each level we took every word form used in the free chapters below it and measured how much of that level's free chapters they cover.
| Level | Contos moves you up at | Different word forms in the free chapters | Covered by every form from the levels below |
|---|---|---|---|
| A1 | Start here | 828 | — |
| A2 | 500 known words | 1,311 | About 76% (the 828 A1 forms) |
| B1 | 1,500 known words | 1,877 | About 79% (1,631 A1–A2 forms) |
| B2 | 4,000 known words | 2,309 | About 84% (2,698 A1–B1 forms) |
Even a reader who knew every word in the lower levels would still meet about one unfamiliar word in four at A2, and one in five at B1. That gap is the point: it is where new words come from, and it is why tapping for a meaning matters more than finishing a word list first.
Which Spanish words should you learn first?
Learn by frequency. A few words do most of the work: in the free chapters of the Contos Spanish library, the 100 most common word forms make up about 53% of all the running words, and the top 500 about 76%. Our list of your first 100 Spanish words is built from the beginner chapters.
For a wider reference, Mark Davies and Kathy Hayward Davies's A Frequency Dictionary of Spanish (second edition, Routledge, 2018) ranks core vocabulary from a web corpus of more than 2 billion words collected from 21 Spanish-speaking countries.
Frequency also explains why you need volume. In the free A1 chapters, 399 of the 828 different word forms (48%) occur only once. A word seen once is rarely learned, so the rarer words only stick if you read enough to meet them again, or review them on purpose.
How do you get to 500, 1,500 and 4,000 words?
- First 100 to 500: the core. Read A1 stories and save the words that keep stopping you. Most of them will be from the list of common forms, because that is what A1 text is made of.
- 500 to 1,500: verbs and everyday nouns. At A2 the past tenses arrive, and one verb gives you several new forms. Save the form you meet; the dictionary form follows.
- 1,500 to 4,000: the long tail. At B1 and B2 more of each chapter is rarer words. Reading a series through gives you repeats; flashcards catch the rest.
- Count words you can understand, not words you can define. Recognising a word in a sentence is what reading needs.

Is 1,000 words enough to speak Spanish?
Enough for simple, slow exchanges about familiar things, which is roughly A2 territory. It isn't enough to follow fast native speech: Nation's estimate for comfortable listening in English is 6,000–7,000 word families.
How many words do I need for B1 Spanish?
No official body fixes a number. Contos moves readers to B1 at 1,500 known word forms, and to B2 at 4,000. Those thresholds are Contos's own, chosen so the stories at each level stay readable with occasional taps.
Does Contos count hablo and habla as two words?
Yes. Contos counts each word form you know, because that is what appears in the text. It makes the level thresholds stricter than counts based on dictionary forms or word families.
Should I memorise a frequency list?
Use it as a checklist rather than a script. Words learned in a story come with context and stick better; a frequency list tells you which ones are worth a flashcard when you meet them.
How many words does it take to read a novel in Spanish?
For English, Nation's 2006 study puts it at 8,000–9,000 word families to know 98% of the words. Expect a similar order of magnitude for Spanish, which is why graded stories come first.
