Words by frequency
Every card is one written Spanish word form, taken from a list ranked by how often the form appears. Where you stop recognising them is the thing being measured.
Free Spanish vocabulary quiz
How many Spanish words do you know?
Grade Spanish words one at a time and get an estimate of your vocabulary, in words. About two minutes, 15 words, no account, and the result is yours either way.
The words come one at a time and you say whether you know each one. The quiz moves towards the point where your knowledge runs out, and stops once it is confident. It checks word knowledge, not grammar or speaking.
What the number means
The result is a count of Spanish dictionary words, each counted once however many forms it has, given as a range — ≈ 1,300–1,900 words you know — and the range is the honest part of it.
Twenty-five self-graded words at most cannot pin a vocabulary of thousands down to one figure, so the quiz prints the bracket its answers support and lets it narrow if you answer ten more. The number inside that bracket sits low on purpose: the estimate is pulled down by its own uncertainty, so the quiz reports below its own best guess rather than above it.
It is a size, not a score and not a grade. The result names one of five steps on the scale below, and that scale is the same one a text’s difficulty is measured against, so a reader and a page can be read against each other.
What it counts is words you recognise. Recognising a word on a card is easier than meeting it in a sentence, and knowing every word in a paragraph is not the same as understanding the paragraph. Treat the number as a starting point that real reading corrects, not a verdict.

What each step looks like in Spanish
A few Spanish words from where each step starts on the list the quiz draws from.
300beginner
ello it · ojo eye · pregunta question · atrás behind, back · comida food · comer to eat
900elementary
silla chair · arreglar to fix · papi daddy · señoría your honor/lordship · llorar to cry · enfermedad illness
1,700intermediate
labio lip · ruso Russian · aliento breath · pesado heavy · nacer to be born · mejorar to improve

6,000advanced
mugre grime/filth · proxeneta pimp · rocío dew · peluquero hairdresser · mezquino stingy/petty · procurador attorney/prosecutor
A result is a position on this list, so a reader at 1,700 is expected to know most of the words that come before that row and fewer of those after it. Words an English speaker would recognise on sight are left out here, as they are in the quiz.
How the estimate is made
02
Three at a time, near your edge
Cards come in blocks of three at roughly one difficulty, and the next block moves towards wherever your answers put you. A run is 15 words, about two minutes, and you can answer ten more to narrow the range.
03
Summed, then read down
The estimate adds up the words below where your answers put you on that list. It is reported as a range, and the figure inside it sits low on purpose, so the quiz under-reads you rather than flattering you.
Words an English speaker would already read without knowing Spanish — hotel, música — are never asked, because a card everybody answers “known” measures nothing. The frequency order behind the cards is published data, credited in full on our sources page.
What to read at your size
A number on its own is trivia. These three are what it is for.
01
Check a text
Paste a page into the Spanish text checker to see the vocabulary that passage asks for, and whether it is above or below your result.
02
See the words
The most common Spanish words are free to read and to download, ranked in the same order the quiz draws from.
03
Find something to read
The Spanish catalogue lists films, books and songs by title, setting and year — somewhere to point the vocabulary.
Frequently asked questions
01
How accurate is a vocabulary size estimate?
It is an estimate, which is why it is reported as a range rather than a single number. Twenty-five self-graded words at most cannot pin down a vocabulary of thousands, and you are the one grading, so nothing is verified. The range narrows if you answer the ten extra cards, and the figure printed inside it sits below our own best guess.
02
Why a word count rather than a language level?
Because a word count is what this measures. A CEFR letter describes reading, writing, listening and speaking, and a set of vocabulary cards has no evidence about three of those, so the quiz does not give one. The result names a step instead: beginner, elementary, intermediate, upper intermediate or advanced, at 300, 900, 1,700, 3,300 and 6,000 words.
03
How many Spanish words do I need to read a newspaper or a novel?
It depends on the text far more than on the number. Our own scale puts following a clear story around 1,700 words and reading novels with a dictionary nearby around 3,300, but a particular article or chapter can sit either side of that. For one specific text, paste a page into the text checker: it reports the vocabulary that passage asks for rather than a guess about the genre.
04
Can I retake it, and can the number go down?
Yes to both, as often as you like. The quiz samples 15 words out of thousands, so two runs a week apart can land in different places without either being wrong — that is what the range is for. Nothing is compared against anyone else and no score is kept unless you choose to save it.
05
Does it test my grammar?
No. It asks whether you recognise a written word, not whether you can conjugate it, hear it or use it in a sentence. A page you cannot read may be a vocabulary problem or a grammar one, and this quiz can only speak to the first.
