What they share
Both are short, cross-cultural, and look beautiful in writing. Both travel internationally without explanation. Both pair well with almost any middle name length.
Pick Ava if…
Pick Ava for the softer, airier sound. Ava is Germanic in origin and means 'bird' in some readings. It has a lightness that suits contemporary taste.
Pick Mia if…
Pick Mia for the warmer, more affectionate sound. Mia means 'mine' in Italian and Spanish, and carries a closeness that Ava does not. Mia also shortens naturally from Maria or Amelia if you prefer a longer formal option.
