Common questions
What twin name goes with Liam?
Matched same-sex options: Jackson, Jacob, Wyatt, Roman.
For a girl twin: Nora, Emma, Mia, Chloe. Each one sits well next to Liam without echoing it. 18 of the 20 names on this page have the same 2-syllable length as Liam.
Should twin names match more than sibling names?
Closer than ordinary siblings, but not all the way. A twin of Liam can share its style and length; what it should not do is rhyme with Liam, which is the biggest penalty in the twin score.
Should Liam's twin have a different first letter?
School registers, medical forms and camp lists often go by first initial and surname. A twin of Liam whose name also starts with "L" can be harder to distinguish from Liam on some records, so the twin score rewards a different first letter. None of the names on this page start with "L".
What are these scores based on?
The popularity ranks for Liam 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.
