how old is kara when she gets to earth

Kara is usually 15 or 16 when she first arrives on Earth in the classic DC comics version, depending on the continuity. In some newer versions, like the Arrowverse, she arrives at 13 but is delayed in a time-warp situation, so her arrival age can look different from her original departure age.

Version matters

• Classic comics: around 15–16 years old when she reaches Earth.

• Arrowverse TV version: 13 when she leaves Krypton, but her arrival is complicated by time spent in the Phantom Zone, so she appears to arrive at the same age she left.

Why the answer changes

Different Superman and Supergirl continuities rewrite Kara’s timeline, so her age depends on which version you mean. The broad pattern is that she arrives as a teenager, not as a child or adult.

TL;DR: Most often, Kara is portrayed as a teenager when she gets to Earth, usually 15–16 , though some versions use 13.
