Common questions

What twin name goes with Carlos?

Matched same-sex options: Javier, Andres, Ivan, Lukas.
For a girl twin: Andrea, Inez, Lucia, Leah. Each one sits well next to Carlos without echoing it. 15 of the 20 names on this page have the same 2-syllable length as Carlos.

How closely should twin names match?

A little. Twins are introduced together for life, so names that sound alike and share a style work well — but names that rhyme (Carlos with a near-rhyme) sound like a comedy act, so they get marked down hard here.

Should Carlos's twin have a different first letter?

Twins share a surname and a birthday, so on forms the first initial is often one way to distinguish their records. A twin of Carlos whose name also starts with "C" can be harder to distinguish from Carlos on some records, so the twin score rewards a different first letter. None of the names on this page start with "C".

Where does the data come from?

The popularity ranks for Carlos and each twin name are from US Social Security Administration records. The pairing score is our own, based on style, length, first letter and sound — the how-we-score page walks through it.
