Comparisons of equality in Spanish – Learn and Practice

Welcome to our grammar lesson about comparisons of equality in Spanish.

Comparisons of equality are those where two things or people are equal in some way.

English sentences like “Dancing is as fun as singing”, or “Ana has as much money as Juan” are comparisons of equality.

We basically use two formulas to make comparisons of equality in Spanish: one with tan como and another one with tanto como.

In this lesson we will learn both formulas and read examples of their use.

At the end you’ll find a Quiz and an Exercise for practice.

Comparisons with “tan como”

tan como means “as… as…

We can only use tan como with an adjective or an adverb in between.


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.

Comparisons with “tanto como”

  • tanto como means “as much… as…”


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

Nosotros dormimos tanto como ellos.
We sleep as much as they do.

If the comparison is about something expressed with a noun, we place that noun between the 2 words of the formula:

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

Also, in this case we need to match tanto to the gender and number of the noun.

That means there are 4 possibilities: tanto / tanta / tantos / tantas
(with the plural forms tantos and tantas, the comparison means “as many… as…”)


La niña come tanta pasta como el niño.
The girl eats as much pasta as the boy.

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

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

Note: Sometimes we may choose to leave a noun unsaid. But we still need to match tanto to the gender and number of that unsaid, implicit noun:

Tengo tantas como tú.
I have as many as you do. (as many of something feminine plural that we have chosen to leave unsaid. For example, it could be “mesas” (tables))
