Premise
The series focuses on quadruplets Nicky, Ricky, Dicky, and Dawn Harper, nine years old at the start of the series, who have nothing in common and often fight, but must work together to navigate everyday situations.

Main

 * Brian Stepanek as Tom, the father of the Harper family quadruplets. It is a running gag in the series that he cares more about his possessions than his children, but he loves his family and is a kid at heart.
 * Allison Munn as Anne, the mother of the Harper family quadruplets who usually gets caught up in Tom's new obsessions.
 * Aidan Gallagher as Nicky, the youngest of the Harper quadruplets. He is shown to be quite comedic, quirky, and easily confused. It is shown that he is a talented chef.
 * Casey Simpson as Ricky, is the second oldest of the Harper quadruplets. He is the smart one of the group, always seen carrying a book or doing his homework. He is also a neat freak and a bit of a goody two-shoes, though he occasionally tries to prove to Dawn and his brothers that he can bend rules as well.
 * Mace Coronel as Dicky, the third oldest and easy-going Harper quadruplet who cares a great deal about his appearance. He always takes the easy way out. He ships himself to Australia in "Quadcodile Dundee".
 * Lizzy Greene as Dawn, the oldest of the Harper quadruplets. Although she's always seen bothering her brothers, she does care about them deeply. There is a consistent rivalry for the leader spot of the quads between her and Ricky.
 * Gabrielle Elyse as Josie (season 1), a worker at Tom's sporting shop and babysitter for Nicky, Ricky, Dicky and Dawn.
 * Kyla-Drew Simmons as Mae (recurring, seasons 1–2; main, seasons 3–4), the quads' friend and Dawn's best friend. She often calls herself "the fifth quad".
