The answers in detail
What size TV should you choose with 2 metres of viewing distance?
At 2 metres, a 55 to 65-inch TV is a sensible starting point for 4K content; some people prefer smaller or more immersive. The right screen size also depends on the real resolution of the programmes and the space available.
What size TV should you choose with 3 metres of viewing distance?
At 3 metres, a 65 to 85-inch screen can be right depending on the immersion you want and the quality of your content. Measure the available space first and allow for the screen's physical width, especially with a unit or wall mount.
Is a 65-inch TV too big for a living room?
A 65-inch TV isn't inherently too big for a living room. Whether it suits you depends on your viewing distance, your main use and the level of immersion you want. A cardboard box the size of the screen helps you visualise how much space it takes up.
Should you buy a 55 or 65-inch TV?
Between 55 and 65 inches, the larger size gives about 40% more picture area. If your viewing distance and budget allow, 65 inches can improve immersion; 55 inches remains a good choice in a compact room or for occasional use.
What's the best 55-inch TV?
The best 55-inch TV is the one whose performance suits your room. For films, check contrast and HDR; for sport, uniformity and motion; for gaming, 4K 120 Hz, VRR and latency if these features matter to you.
What's the best 65-inch TV?
At 65 inches, compare an OLED and a Mini LED in the same price bracket, with your own uses in mind. Perceived quality depends a lot on ambient lighting and on how the set handles compressed content or content below 4K resolution.
What's the best 75-inch TV?
At 75 inches, LCD and Mini LED models are often the most numerous and can deliver strong immersion. Check the dimensions, weight, the stability of the stand and the quality of the backlight: a large screen magnifies the flaws of poor sources.
Is an 85-inch TV worth the investment?
An 85-inch TV is worth the investment if you have adequate viewing distance, a safe place to put it and good-quality sources. Also factor in the extra costs: suitable delivery, wall bracket, fixings and possibly professional installation.
Which 98-inch TV should you choose in Belgium?
For a 98-inch TV in Belgium, start with the actual dimensions, access to your home and the packed weight. Then compare the panel technology, the number of local dimming zones where documented, motion handling, ports and delivery terms.
At what height should you mount a TV on the wall?
The ideal height puts the centre of the screen roughly at seated eye level, adjusted to suit your household's comfort. To avoid neck strain, don't mount the screen unnecessarily high and check your actual viewing position.
What to check before you buy
The stated size is the diagonal: about 140 cm for 55 inches, 165 cm for 65 inches and 191 cm for 75 inches. Check the actual width, the depth of the stand, the weight and whether it fits through doorways. The right level of immersion is a matter of taste.
