That depends on your room’s dimensions, seating arrangement, viewing distance, and budget. Larger displays are ideal for spacious living rooms and dedicated home theatres, while smaller screens easily fit in your kitchen, bedroom, or office. Larger screens typically use 4K UHD resolution to provide an unmatched level of immersion, while smaller screens are generally more affordable. If you decide to buy a large-screen smart TV at 55″ and above, you should place it at a safe distance of at least one meter from your seat to prevent eye strain and other health issues.
