Common questions

What twin name goes with Jason?

Matched same-sex options: Lukas, Ares, Leandro, Angel.
For a girl twin: Sophie, Athena, Phoebe, Daphne. They share Jason's general style but each keeps its own sound. 19 of the 20 names on this page have the same 2-syllable length as Jason.

How closely should twin names match?

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

Should Jason's twin have a different first letter?

A lot of paperwork, from class lists to doctor's files, shows only a first initial and a surname. A twin of Jason whose name also starts with "J" can be harder to distinguish from Jason on some records, so the twin score rewards a different first letter. None of the names on this page start with "J".

Where does the data come from?

Jason's rank and the ranks of the twin names above come from US Social Security Administration records; how well each pairs with Jason on style, length and sound is scored by NamePairings — see the how-we-score page.
