Limiting screen is certain to be good for young kids, especially when it will help limit their exposure to advertising, but I doubt that three hours of screentime for teenagers is a realistic limit. Schoolwork alone will require a large chunk of that. Teens will use screens to keep in touch with friends and explore their own interests in ways that a young child really doesn't. You want your kids to have the opportunity to get nerd sniped or get lost in some rabbit hole, get school work done, socialize, and still enjoy a reasonable amount of films, television, music, etc. When a single episode of a TV show can be 45-60+ minutes it'd be very hard to budget that kind of time. I'd worry more about what older kids are doing with their screen time than a specific limit on the number of hours they spend.
