Comparatives in Spanish: Más Que, Menos Que, Tan Como

You want to say "my brother is older than me," so you build it word by word: mi hermano es más viejo que yo. Understandable — but a native speaker would wince slightly, because for age Spanish has a dedicated word: mayor. Comparatives are one of those topics where the basic pattern is easy and the exceptions are exactly where you'll slip.

The short version: Superiority is más + adjective + que (más alto que, taller than). Inferiority is menos + adjective + que. Equality is tan + adjective + como (tan alto como, as tall as). Four adjectives ignore más entirely: mejor, peor, mayor, menor. And before a number, "than" is de, not que.

Comparisons of superiority: más… que

To say something has more of a quality, wrap the adjective in más… que. Word for word it's "more ___ than."

Spanish	English
Ana es más alta que Luis.	Ana is taller than Luis.
Este café es más caro que el otro.	This coffee is more expensive than the other.
Madrid es más grande que Sevilla.	Madrid is bigger than Seville.

The adjective still agrees with the noun it describes, exactly as always: Ana es más alta (feminine), los libros son más caros (masculine plural). The más… que frame doesn't change that.

Comparisons of inferiority: menos… que

The mirror image. Swap más for menos ("less") and keep que.

Spanish	English
Luis es menos alto que Ana.	Luis is less tall than Ana.
Este café es menos caro que el otro.	This coffee is less expensive than the other.
Hoy estoy menos cansado que ayer.	Today I'm less tired than yesterday.

English often prefers "not as… as" over "less…," but in Spanish menos… que is completely natural and used all the time.

Comparisons of equality: tan… como and tanto… como

To say two things are equal, the pattern changes. You do not use que here — you use como. There are two versions depending on what you're comparing.

With an adjective or adverb, use tan… como ("as… as"). Tan never changes.

• Ana es tan alta como Luis. — Ana is as tall as Luis.
• Este coche es tan rápido como el tuyo. — This car is as fast as yours.
• Corre tan rápido como yo. — He runs as fast as I do.

With a noun (comparing quantity), use tanto… como — and here tanto does agree in gender and number with the noun.

Form	Used with	Example
tanto	masculine singular noun	tanto dinero como (as much money as)
tanta	feminine singular noun	tanta paciencia como (as much patience as)
tantos	masculine plural noun	tantos libros como (as many books as)
tantas	feminine plural noun	tantas amigas como (as many friends as)

The trap: use tan before an adjective and tanto/a/os/as before a noun. Saying tanto alto or tan dinero is a classic mistake. Ask yourself: am I comparing a quality (adjective → tan) or an amount of stuff (noun → tanto)?

The four irregular comparatives

Four common adjectives have their own comparative form and do not take más. Building "más bueno" or "más viejo" for these is the single most common comparative error learners make.

Adjective	Comparative	Meaning
bueno (good)	mejor	better
malo (bad)	peor	worse
grande / viejo	mayor	older / bigger, greater
pequeño / joven	menor	younger / smaller, lesser

These four have no separate feminine form — mejor and peor work for both genders — but they do add -es in the plural: mejores, peores, mayores, menores. Examples:

• Este restaurante es mejor que ese. — This restaurant is better than that one. (not más bueno)
• Mi nota es peor que la tuya. — My grade is worse than yours. (not más mala)
• Mi hermano es mayor que yo. — My brother is older than me. (not más viejo)
• Soy menor que mi prima. — I'm younger than my cousin. (not más joven)

One nuance worth knowing: mayor and menor are the go-to words for age. For plain physical size you can still say más grande and más pequeño — una casa más grande (a bigger house) is perfectly correct. But when comparing people's ages, always reach for mayor and menor.

"Than" before a number: de, not que

This is a small rule with a big payoff, because getting it wrong is instantly noticeable. When "than" is followed by a number or a quantity, Spanish uses de instead of que.

Spanish	English
Tengo más de veinte libros.	I have more than twenty books.
Costó menos de cincuenta euros.	It cost less than fifty euros.
Hay más de mil personas.	There are more than a thousand people.

Compare: Tengo más libros que tú (I have more books than you — comparing two people, so que) versus Tengo más de veinte libros (comparing against a number, so de). If a number comes right after "than," it's almost always de.

Superlatives: the most, the -est

A comparative ranks one thing against another; a superlative ranks one thing against a whole group ("the tallest of all"). The pattern is el/la/los/las + más/menos + adjective + de. Note that "in/of the group" is de, where English would say "in."

• Es el más alto de la clase. — He's the tallest in the class.
• Es la ciudad más grande del país. — It's the biggest city in the country.
• Son los menos caros de la tienda. — They're the least expensive in the store.

The irregulars work here too: el mejor restaurante de la ciudad (the best restaurant in the city), mi hermano mayor (my older/oldest brother).

The absolute superlative: -ísimo

There's a second kind of superlative that compares against nothing — it just means "extremely." You form it by dropping the final vowel and adding -ísimo (with its four agreeing forms: -ísimo, -ísima, -ísimos, -ísimas). Guapo → guapísimo (extremely handsome); caro → carísimo (super expensive).

Watch the spelling changes. To keep the original sound, the consonant before the ending shifts:

Adjective	Change	-ísimo form
rico (tasty/rich)	c → qu	riquísimo
largo (long)	g → gu	larguísimo
feliz (happy)	z → c	felicísimo
fácil (easy)	keeps stem	facilísimo

These aren't random: rico becomes riquísimo because "ci" would sound different from "co," so the spelling switches to qu to preserve the hard "k" sound. Same logic for largo → larguísimo. It's one of the most fun, expressive corners of Spanish — ¡Está buenísimo! (It's absolutely delicious!) sounds far livelier than muy bueno.

Frequently asked questions

When do I use "que" and when do I use "como" in comparisons?

Use que for comparisons of superiority and inferiority: más alto que, menos caro que. Use como for comparisons of equality: tan alto como, tanto dinero como. A quick rule of thumb: más and menos pair with que, while tan and tanto pair with como.

Why can't I say "más bueno" for "better"?

Because bueno has an irregular comparative: mejor. The same goes for malo → peor, grande → mayor, and pequeño → menor. These four never take más. Saying más bueno is one of the most common learner errors, so train yourself to reach for mejor instead.

What's the difference between "tan" and "tanto"?

Use tan before an adjective or adverb (tan alto como, as tall as). Use tanto before a noun, and make it agree in gender and number: tanto dinero, tanta paciencia, tantos libros, tantas amigas. If you're comparing an amount of something, it's tanto; if you're comparing a quality, it's tan.

When do I use "de" instead of "que" for "than"?

Use de when "than" is followed by a number or a specific quantity: más de veinte libros (more than twenty books), menos de cincuenta euros. Use que when comparing two things or people: más libros que tú. If a number comes right after "than," it's de.

How do I form the -ísimo superlative correctly?

Drop the final vowel and add -ísimo, agreeing in gender and number: caro → carísimo, guapa → guapísima. Watch the spelling shifts that preserve the sound: rico → riquísimo (c→qu), largo → larguísimo (g→gu), feliz → felicísimo (z→c).
