Since Fox Sports is broadcasting the 2023 game in 4K, a UHD/4K or 8K TV will provide the best visuals and enable viewers seated to the sides to have the same crisp, clear images as those directly in front of the screen.
For a Super Bowl party where there will be lots of people, you want to have at least a 60-inch TV that is mounted on the wall if the seating arrangements will be farther than 9 feet from the TV.
Mounting the TV on the wall versus sitting on a stand also makes for a better viewing experience. The middle of the screen should be at eye level and directly in front of those seated.
Most likely, this is not the kind of party where there will be a lot of standing and mingling; folks will want to be around the TV, devouring snacks and cheering for their favorite team.
