How sibling harmony is calculated

The score is deterministic; the same two names always yield the same result. The five factors:

Shared origin (30%): Origin match (30%): Addison has origin various origins. When both names share this region or language, the pair scores higher and tends to sound thematically consistent.
Phonetic rhythm (25%): Phonetic weight 25%: 3 syllables Addison and first letter A. Names with 3 or 2 beats and same initial letter get a bonus.
Popularity band (20%): Popularity band (20%): names in similar usage bands (top 100, top 500, top 1000, other) tend to feel cohesive. Addison is in the other band; pairing with the same or adjacent band scores higher.
Length balance (15%) and style cluster (10%): Length 15%, style 10%: balanced character count and shared style category complete the five factors.

Result is reproducible: identical name pair yields identical score.

How we calculate sibling harmony

The harmony score is a weighted sum of five factors, each scored 0–100, then combined with fixed weights. Shared origin (30%) reflects whether two names come from the same cultural or linguistic background; same origin scores 100, partial 50–60, different 0. Phonetic rhythm (25%) rewards similar syllable count and optional first-letter match so names sound good when said together. Popularity band (20%) compares usage tier (top 100, top 500, top 1000, or other); names in the same band score higher so sibling names feel balanced in familiarity. Length balance (15%) and style cluster (10%) round out the formula. The result is deterministic: the same two names always get the same score. For Addison, the table above shows scores from 85–85. Rhythm and origin together carry 55% because auditory cohesion and cultural consistency drive most parents' sense of "these names go together."

Stylistic cohesion across siblings

First-letter diversity varies by family: some parents want matching initials (e.g. Addison and a sibling starting with A); others prefer variety. Our table includes both—same-letter names get a rhythm bonus, but strong origin and style matches can score high without it. Cultural consistency matters: Addison and the top candidates are scored for shared or complementary origin, which drives 30% of the score. Length contrast is balanced so one name doesn't dominate: Addison has 3 syllable(s); the suggested names average about 3.0, keeping the set cohesive. Generational naming patterns are reflected in the popularity band (20%): names in similar usage tiers often feel like they belong to the same era, which helps sibling sets feel intentional rather than random.
