FAQ About Mario and Luigi's Ages

Are Mario and Luigi definitely twins?

Yes. Nintendo has confirmed this multiple times in official publications and interviews, though they rarely emphasize it in games themselves.

Why is Mario considered the older brother?

While twins, Mario was born first (even if just by minutes). This, combined with his more assertive personality, establishes him as the "older" brother in their dynamic.

Has their age gap ever changed?

In very early Western localizations (pre-1990), Luigi was sometimes portrayed as significantly younger, but Nintendo has consistently maintained their twin status in Japanese materials.

Do they have the same birthday?

While Nintendo hasn't officially established their birthday(s), being twins would mean they share a birthday. Fans often celebrate "Mario Day" on March 10 (MAR10).

Conclusion

Despite their different personalities creating an "older brother/younger brother" dynamic, Mario and Luigi are canonically fraternal twins with virtually no age gap. Nintendo has consistently maintained this since the mid-1990s, even if early Western interpretations sometimes portrayed Luigi as significantly younger.

Their twin status explains why they're always portrayed as peers capable of the same feats (just with different approaches), and why they're shown as babies together in Yoshi's Island. While Mario will always be the "older brother" by minutes, their identical ages make them one of gaming's most iconic sibling duos - proving that even twins can have dramatically different personalities!
