Comparisons of Equality in Spanish – Formulas “Tan como” and “Tanto como”

Welcome to our grammar lesson about Spanish Comparisons of Equality.

Comparisons of Equality are comparisons in which two things or people are equal in some way. For example, the sentences in English “football is as fun as basket”, or “this person has as much money as this other person” are comparisons of equality.

In order to do comparisons of equality in Spanish, we basically use two formulas: the formula “tan como” and the formula “tanto como”.

In this lesson we will learn and practice both formulas for comparisons of equality in Spanish, providing example sentences. At the end you’ll find a Quiz and an Exercise for practice.

1. Comparisons of equality with the formula “tan como”

We use the formula “tan como” when the concept in which two things are equal is represented by an adjective or an adverb. That adjective or adverb must be placed between “tan” and “como”.

Examples:

Mi hermano es tan alto como yo.
My brother is as tall as I am.

Los atletas corren tan rápido como un tigre.
The athletes run as fast as a tiger.

Sus hermanas son tan listas como ella.
Her sisters are as smart as she is.

Remember: we always need an adjective or adverb between “tan” and “como”.

2. Comparisons of equality with the formula “tanto como”

We use the formula “tanto como” when the concept in which two things are equal is represented by a noun or a verb.


In the case of a verb , “tanto como” is placed right after the verb. Also, In this case, “tanto” has no gender or number variation: it is always “tanto”.

Example:

María lee tanto como Ana.
María reads as much as Ana.


In the case of a noun, that noun ins placed between the two words of the formula. In this case, we need to match the word “tanto” to the gender and number of that noun, which results in 4 possible forms:

  • tanto
  • tanta
  • tantos
  • tantas

Examples:

Paco tiene tanto dinero como Manuel.
Paco has as much money as Manuel.

La niña ha comido tanta pasta como el niño.
The girl has eaten as much pasta as the boy.

Hay tantos barcos en el mar como ayer.
There are as many ships on the sea as yesterday.

Mi barrio tiene tantas bibliotecas como el tuyo.
My neighborhood has as many libraries as yours.

It is also possible to leave the noun unsaid:

Tengo tantas como tú.
I have as many as you. (as many of something feminine plural that is not explicitly mentioned in the sentence)


Note: “tan como” becomes “tanto como” if we don’t say the adjective or adverb in between


We have already explained that the “tan como” formula always needs an adjective or adverb in between.

And actually, if we don’t place an adjective or adverb in between, it turns into “tanto como”.

Look at this exchange, where the answer turns into “tanto como” because we don’t mention the adjective “interesante” again:

¿La película es tan interesante como el libro?
Is the movie as interesting as the book?

Sí, tanto como el libro.
Yes, as much as the book.
