Common questions

What twin name goes with Ian?

Matched same-sex options: Collin, Gavin, Patrick, Trevor.
For a girl twin: Nora, Ava, Leah, Eva. Each one sits well next to Ian without echoing it. 17 of the 20 names on this page have the same 2-syllable length as Ian.

Should twin names match more than sibling names?

Closer than ordinary siblings, but not all the way. A twin of Ian can share its style and length; what it should not do is rhyme with Ian, which is the biggest penalty in the twin score.

Why avoid two names starting with "I" for twins?

School registers, medical forms and camp lists often go by first initial and surname. A twin of Ian whose name also starts with "I" can be harder to distinguish from Ian on some records, so the twin score rewards a different first letter. None of the names on this page start with "I".

Where do these rankings come from?

The popularity ranks for Ian 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.
