How to choose your TV size
Measure the distance from your sofa to the screen and select the resolution you expect to watch most often. This tool gives an indicative result, not a mandatory size. Consider viewing comfort, available wall space, glare, streaming resolution and budget.
Before buying a TV
- Check the screen’s actual width, not only its diagonal measurement.
- Compare 4K and Full HD for your common viewing content.
- Allow space for ventilation, cables and a suitable mount or stand.
