To say you have as much or as many of something as something else in Spanish, we use tanto ... como if the thing we are comparing is a noun, or tanto como if what we are comparing is a verb.
Using tanto ... como with nouns
Notice we use tanto, tanta, tantos, or tantas in order to agree in number and gender with the noun that follows.
Using tanto como after a verb
Note that tanto como never changes with verbs.
Unlike in English, you don't repeat the verb at the end:
Él tiene tanta paciencia como ella tiene.
He has as much patience as she does.
Él tiene tanta paciencia como ella tiene.
He has as much patience as she does.
