Many 12 year olds can on calm, shallow water close to shore with an adult nearby, if they swim confidently and keep their life jacket on. Start with short sessions and a clear boundary.
At about 89 lb, a USCG Youth (50-90 lb) jacket. Kids' jackets are sized by weight, and it must pass the shoulder-lift test: lifted at the shoulders it must not ride up past the chin. Children must wear one on the water in most states.
On the water: Wear a properly fitted, USCG-approved life jacket every time, dress for the water temperature rather than the air, and check your state and local paddling regulations before you launch.
This is researched general information, not professional advice. Sizing figures are starting points: confirm against the maker's own sizing chart and the capacity printed on the boat or board.
