"So Small" is a song co-written and recorded by American country music artist Carrie Underwood.

Underwood co-wrote the song "I Ain't In Checotah Anymore" but it was not released as a single from her debut album, Some Hearts.

[5] The video begins with a teenager girl walking down a country road alone at dusk, carrying only a backpack.

Two cars are then shown approaching her from opposite ends, driven by a man (played by Christian Kane) and a crying woman.

The woman swerves to the left side of the road to avoid hitting her, colliding instead with the man's car.

Underwood is also seen throughout the video standing in the middle of the road in separate shots, singing both at night and in the morning.

"So Small" debuted at number 20 on the Billboard Hot Country Songs on August 18, 2007, surpassing the number 21 debut of Gretchen Wilson's "All Jacked Up" to becoming the highest chart entry by a solo country female artist in 43 years of Nielsen BDS history.
