Units

Stray Kids' units are formed through music and variety content. None of these units have had an official debut.

The units are often called racha, a naming convention coined after 3RACHA. The official definition of a racha is "a sub-unit of +-3 members" (RACHA LOG).

• Dongsaeng Line - Hyunjin, HAN, Felix, Seungmin, I.N

Age debate

Hyunjin was historically in the maknae line, but since Woojin left the group, there is a long lasting debate within the fandom about whether Hyunjin should now be in the hyung line. More and more people consider that he is a hyung, while other fans argue that he is very close in age with the maknaes. Thus, several age combinations exist:

• Hyung Line (Bang Chan/Lee Know/Changbin/Hyunjin) / Maknae Line (HAN/Felix/Seungmin/I.N)
• Hyung Line (Bang Chan/Lee Know/Changbin) / Dongsaeng Line (Hyunjin/HAN/Felix/Seungmin/I.N)
• Hyung Line (Bang Chan/Lee Know/Changbin) / Members in the middle (Hyunjin/HAN) / Maknae Line (Felix/Seungmin/I.N)
• Hyung Line (Bang Chan/Lee Know/Changbin) / 00 Line (Hyunjin/HAN/Felix/Seungmin) / Maknae (I.N)

Trivia

• There is a running joke that Seungmin wants to join 3RACHA and rap, while I.N has said that he wants to join DANCERACHA.
