Basic meanings: maior and mais grande
Maior is the comparative form of the adjective grande and generally translates to bigger, larger, or greater in English. It is the standard comparative used with grande and can express physical size, age, quantity, or abstract magnitude.
Mais grande literally means more big and is a construction using the adverb mais plus the adjective grande. In modern Brazilian Portuguese, mais grande is less common and often sounds redundant, but it can appear in colloquial speech or for emphasis.
When to use maior: the default comparative
Use maior whenever you need the regular comparative of grande. It is grammatically correct, idiomatic, and the preferred option in most contexts.
Examples:
Casa maior
O prédio é maior do que aquele.
Idade maior
Meu irmão é maior do que eu.
Quantidade ou importância
Este problema é maior do que parece.
When mais grande can appear
Mais grande may appear in spoken Brazilian Portuguese for stylistic reasons, emphasis, or dialectal variants. It is more likely when speakers want to stress an increase in size or contrast two stages explicitly, as in more big rather than simply bigger.
Examples where you might hear mais grande:
Agora a sala está mais grande com os móveis novos.
Ele ficou mais grande depois do verão.
Note that while these sentences are understandable and often used colloquially, replacing mais grande with maior would typically sound more natural and concise.
Size versus age: choosing maior or mais velho
When comparing age, Portuguese speakers often prefer mais velho rather than maior. Although maior can technically indicate age (older), mais velho is more idiomatic for people and living beings.
Examples for age:
Ele é mais velho do que eu.
Minha avó é a pessoa mais velha da família.
Examples where maior would be awkward for age:
Incorrect or unusual: Ele é maior do que eu. (This could be interpreted as taller or physically bigger rather than older.)
Correct substitute: Ele é maior do que eu em altura. or Ele é mais velho do que eu.
Comparative structures: maior than and mais … do que
Comparisons in Portuguese commonly use two structures: the single-word comparative maior and the periphrastic construction with mais plus an adjective followed by do que.
Structure with maior:
Sujeito + é + maior + do que + objeto.
A casa é maior do que o apartamento.
Structure with mais + adjective:
Sujeito + é + mais + adjetivo + do que + objeto.
A sala é mais ampla do que a cozinha.
Note that with grande, the idiomatic choice is maior, but grammatically you can build comparisons with mais grande if you want to highlight the degree in informal speech.
Superlatives and relative comparisons
For superlatives, Portuguese uses the definite article and the comparative form or the adverb muito and suffixes like -íssimo. With grande, the common superlative is o maior for the absolute relative superlative and grandíssimo is rare and literary.
Examples:
O prédio mais alto da cidade ou O maior prédio da cidade.
Ele é o maior jogador do time.
When describing extreme size, Brazilians might prefer paraphrases:
A casa é enorme. or A casa é muito grande.
Agreement and gender
Maior is invariable in gender for most adjectives ending in -or, meaning the same word serves both masculine and feminine: maior for both o carro maior and a casa maior. Number agreement does occur: maiores for plural forms.
Examples:
O cachorro é maior.
A cadela é maior.
Os prédios são maiores.
As árvores são maiores.
Contextual nuance: physical size, age, importance
Understanding the nuance is crucial. Maior covers physical size, but it also commonly expresses abstract measures like importance, degree, or intensity. Context usually clarifies meaning.
Physical size: A mala é maior do que eu pensei.
Age or seniority (prefer mais velho): Ele é mais velho do que ela.
Importance or degree: Este problema é maior do que esperávamos.
Colloquial and emphatic uses of mais grande
In casual conversation, Brazilians sometimes use mais grande for emphasis, to contrast stages, or to mirror English phrasing like more big. This use is informal and may be regionally more frequent. For learners, it is safe to recognize it but prefer maior in formal writing and clear speech.
Examples of emphasis:
Quando a árvore cresceu, ela ficou mais grande do que antes.
Com as reformas, a casa ficou mais grande.
Negative and comparative combinations
Comparatives combine with negation and other modifiers without special changes. Use maior + do que or mais + adjective + do que as needed.
Examples:
Não é maior do que eu imaginava.
Não ficou mais grande depois da obra.
Common mistakes and tips to avoid them
1. Confusing age and size: Use mais velho for older people to avoid ambiguity. If you say ele é maior, listeners might think you mean taller or larger.
2. Overusing mais grande: It is understandable but less idiomatic than maior. Favor maior in writing and formal speech.
3. Forgetting plural agreement: Remember maior becomes maiores in plural contexts.
4. Direct word-for-word translation: English uses more big rarely; Brazilians prefer maior. Translate ideas, not words.
Practical examples with translations
Below are concise Portuguese examples with English glosses to illustrate correct usage.
O prédio é maior do que o outro.
The building is bigger than the other.
Minha irmã é mais velha do que eu.
My sister is older than me.
A cidade ficou mais grande com o novo bairro.
The city became larger with the new neighborhood.
Este projeto é maior do que esperávamos.
This project is bigger/more significant than we expected.
As flores são maiores este ano.
The flowers are bigger this year.
Cultural and register notes
Brazilians tend to use concise comparatives in everyday speech, so maior is common and natural. In regional speech or for rhetorical effect, you may hear mais grande. Formal writing, news, academic texts, and standardized tests will favor maior. Knowing both forms helps you understand spoken Portuguese across regions and registers.
Also note that speakers may choose synonyms depending on nuance: enorme, amplo, vasto, and maior have different connotations, so pick the word that fits the context rather than relying on a literal comparative in every case.

Conclusion
Mastering the difference between maior and mais grande will make your Portuguese comparisons clearer and more natural.
