Noun comparatives (tanto como)

To compare quantities of nouns—meaning "as much as" or "as many as"—use tanto + [noun] + como.

Because tanto describes a noun, its ending changes to match the noun's gender and number.

"As Much As" (Singular Nouns)

Use tanto / tanta for singular, uncountable nouns like smoke or pollution.

There isn't as much smoke here as over there.
Aquí no hay tanto humo como allí.
The village doesn't have as much pollution as the city.
El pueblo no tiene tanta contaminación como la ciudad.

You can use this structure to contrast city life with rural environments:

There is never as much stress in the countryside as in the office.
En el campo nunca hay tanto estrés como en la oficina.

"As Many As" (Plural Nouns)

Use tantos / tantas for plural, countable nouns.

A village doesn't have as many inhabitants as a city.
Un pueblo no tiene tantos habitantes como una ciudad.

You can easily turn this pattern into a question:

Are there as many inhabitants in Spain as in France?
¿Hay tantos habitantes en España como en Francia?
