Quick answer
Tackle football is full contact, 11 a side at most levels, with helmets and pads. Flag football removes tackling: players pull flags, teams are smaller (NFL FLAG youth plays 5 on 5), and gear is minimal. 7v7 is a passing format with no linemen, often used for offseason training, with soft-shell headgear allowed in many leagues. Flag and 7v7 cost far less to start.
Three formats, very different gear lists.
