Most 12-year-old boys ask for something tied to a current interest, such as video games, sports equipment, building kits, headphones, or books and graphic novels. Gifts that help them play with friends or learn a skill tend to be used the longest.
Most people spend $20-$40 for a friend or classmate and $40-$100 for a nephew, grandson, or son. Bigger items like headphones or sports gear can run higher, so splitting the cost with relatives is common.
Good non-screen options include model kits, advanced building sets, strategy board games, sports gear, art supplies, and chapter book series. Pick something with a clear challenge or goal, since kids this age like finishing a project and showing it off.
