You're standing between two food stalls in a market in Valparaíso, trying to tell your friend which empanada looks better, and every sentence you try comes out wrong: "esta empanada es más buena" just doesn't sound right, but you can't remember why. Comparing things — this one versus that one, older, cheaper, as good as — is something you do constantly in everyday conversation, and Spanish has a clean, learnable system for it once you see the pattern.
English comparatives are messy: you add "-er" to short words (bigger, faster) but "more" to long ones (more expensive), plus irregulars (good → better, bad → worse) you just memorize. Spanish is more consistent — one basic structure covers almost every adjective, no "-er" ending to worry about — but that consistency hides a few real traps: a small set of irregular comparatives native speakers use constantly, and a "than" that isn't always the word que you'd expect. Get the pattern down once and you'll compare prices, sizes, people, and places in natural Spanish almost immediately.
The core structure for "more than" and "less than" in Spanish is simple and doesn't change based on the adjective's length or ending, unlike English:
[AUDIO: más que] [AUDIO: menos que]
One exception worth flagging early: when you're comparing against a specific number rather than another noun, Spanish switches from que to de — "más de veinte" (more than twenty), not "más que veinte." This trips up a lot of learners because que feels like the safe default everywhere else.
When two things are equal rather than one being more or less than the other, Spanish uses a different structure entirely, and this is where a lot of English speakers default incorrectly to más...que even when they mean "just as."
For adjectives and adverbs, use tan + adjective/adverb + como:
For comparing nouns — amounts of something — use tanto/tanta/tantos/tantas + noun + como, and this is the one place the word has to agree in gender and number with the noun that follows it:
Common mistakes:
A small handful of very common adjectives skip the más + adjective pattern entirely and use their own short comparative word instead — much like English "good" becomes "better," not "more good."
"Más bueno" and "más malo" aren't grammatically forbidden the way "more better" is in English, but they sound childish to a native speaker's ear — stick to mejor and peor in normal conversation. For size, mayor and menor skew toward age or importance ("mi hermano mayor," my older brother) while más grande and más pequeño are what you'll actually reach for to describe an object, a city, or a portion of food.
Chile and Peru have argued for decades over whose pisco is better — the grape brandy both countries claim as their own national drink. Order a pisco sour in Santiago and say it's "mejor que el peruano" and you'll get a passionate, good-natured argument, not agreement; order the same line in Lima with the countries reversed and you'll get the exact same reaction. It's a rivalry built almost entirely out of comparative sentences.
Once you can compare two things, the superlative — singling out the most or least of a whole group — only needs one small addition: el, la, los, or las before the comparative structure, plus de instead of que to introduce the group being compared against.
The irregulars carry over unchanged — el mejor, el peor, el mayor, el menor — just add the article and swap que for de. One bonus form worth knowing: adding -ísimo/-ísima to an adjective creates an absolute superlative with no comparison at all, just intensity — carísimo (super expensive), riquísimo (super delicious) — you'll hear this constantly in casual speech.
Picture yourself back at that market in Valparaíso, empanada in each hand. Now you can settle the debate: "Esta está más rica que esa, pero esa es más grande" (This one is tastier than that one, but that one is bigger). Haggling over price works the same way — "¿Tiene algo menos caro?" (Do you have something less expensive?) is one of the most useful sentences a traveler can carry around a market. And with more than two options, the superlative takes over naturally: "De todas, esta es la más rica" (Of all of them, this one is the tastiest).
