The size of your screen not only depends on how much wall space you have, but also how far away you will be sitting.

Use the screen size as a guide to how far you should sit in inches. The viewing distance should be about 1.5 times the screen size.

If you have a 1080p TV, you should use the farthest viewing distance listed below.

Television screens have continued to grow in size since their inception.

While old TVs maxed out at around 40 inches, these days you can get more than double that.

In general, modern TVs vary from 32 inches to the world’s largest TV at 325 inches, although domestic models usually stop at around 80 inches.

Most people get between 40-inch and 75-inch TVs, as larger ones can still be a lot more expensive.

Once you’ve chosen the TV size you want, you need to think about what resolution you want.

The better the resolution, the more expensive your TV will be, so when in doubt it’s a good idea to stick with a 4K TV.

Resolution is measured by how many pixels the TV has, meaning you can sit closer to the TV before it starts to pixelate.

If you’re confused about HD and 4K TVs, this should provide some clarity.

Full HD or 1080p

This means televisions with a resolution of 1920 x 1080 pixels.

These are best suited for smaller TVs that you’re watching from a distance, say 32 or 40 inches.

Ideal for budget TVs that don’t need to be crystal clear or large e.g. B. in the kitchen.

We recommend Samsung’s T5300 Full HD Smart TV 32 inches for a smart TV without the high price.

If you’re going for a TV larger than 40 inches, it’s best to up the resolution to 4K.

This screen, commonly known as Ultra HD or UHD, would have a resolution of 3840 x 2160 pixels.

Most smart TVs have this by default as it offers four times the pixel resolution of an HDTV.

If you’re looking for a great option for your living room TV, this Panasonic 50-inch 4K TV might be perfect for you.

8K is the next resolution level with 7680 x 4320 pixels and is also called Ultra HD.

It might be worth it if you have the cash, but the market for these types of TVs is still thin.

Other things to consider

Consider whether you want to mount the TV on the wall or put it on a TV stand.

This can change the viewing distance and the space available for the TV.

Wall mounting a TV can give you an extra foot of viewing distance and potentially allow for a larger screen size.

Also consider how much movement the room has. Can you put your sofas back to accommodate a larger screen size, can’t you?

Samsung’s OLED or QLED technology means a 4K TV offers the best possible screen quality, so you may not need to upgrade to an 8K TV.
