How close should you sit to a 4K TV? 

The suggested viewing distances in the tool above are based on high-definition televisions, but many now come with 4K ultra HD screens, meaning you can sit that little bit closer. Pictures on these TVs can have four times the detail of a Full HD set, but you really need to go 40-inch or larger to appreciate the jump in picture quality. 

Because of the extra detail in the picture, it isn't uncomfortable to sit closer. For example, with a 40-inch 4K TV you can sit around 8.3 feet away from it. For a 50-inch, that goes up to 10.4 feet, and for a 55-inch, 11.4 feet. 

Ultimately, though, how close you sit to your TV - whether it's a HD or 4K model - is down to your own personal preference and the way you've set up your living room.

After you've decided which size TV is best for you, the other pages in this guide round up the best 32-inch, 40 to 43-inch, 49 to 55-inch, and 60 and 65-inch TVs from our rigorous, independent testing.

Other things to consider

Viewing angle: Some TVs can lose colour accuracy and contrast when you're not watching the picture directly straight on. It's a bit like the image is being washed out. With TVs, this can be a problem if you have a narrow living room or often watch TV with a big group of people. Check our expert reviews for viewing angle ratings for every television that we test. 

Curved screens: Many TVs from the big brands now have curved screens rather than flat. They're claimed to 'wrap' the picture around you like with IMAX, but the effect is subtle at best, and you have to sit straight on to really see it. Also, the screens can occasionally appear a little warped, particularly when lights reflects off them.
