Smart TV Buying Guide: What Size and Resolution Do You Need?

Today’s televisions are packed with features. This guide keeps it simple.
Screen size and viewing distance
As a rule of thumb, sit about 1.5 to 2.5 times the screen’s diagonal away. For example, with a 43-inch TV a distance of roughly 1.6 to 2.7 metres works well. Measure your wall space before buying.
Resolution
- Full HD: fine for smaller screens and a tight budget.
- 4K (Ultra HD): noticeably sharper on 43 inches and above, and a good future-proof choice.
Smart features
Smart TVs include apps for streaming services and YouTube. Check Wi-Fi support, available apps and how easy the remote and menus are to use.
Connections
Make sure there are enough HDMI and USB ports for your set-top box, sound bar, gaming console or pen drive.
Sound
Thin TVs often have modest speakers. If you love movies or music, consider adding a sound bar.
Installation and safety
- Use a quality wall mount rated for the TV’s weight.
- Connect it through a surge protector.
- Keep the vents clear for airflow.
