Some common sizes for TVs based on the diagonal dimensions of the screen include 24 in (61 cm), 28 in (71 cm), 32 in (81 cm), 42 in (110 cm). 48 in (120 cm), 60 in (150 cm), 65 in (170 cm), 70 in (180 cm), and 85 in (220 cm). [2] X Research source You can also find TVs with screens as big as 98 in (250 cm) or larger. The largest TV currently on the market for household entertainment is LG’s 8K DVLED TV at a whooping 325 in (830 cm). [3] X Research source
For example, a TV listed as 60 in (150 cm) will only be about 52. 3 inches (133 cm) wide. Your TV’s width is its most crucial measurement. This is how you can find out if a TV will fit on your stand or cabinet.
For example, a TV with a screen that is advertised as 48 in (120 cm) will be about 42 inches (110 cm) wide and have a height of around 25–27 inches (64–69 cm). Generally speaking, height doesn’t matter as much as width. However, the vertical dimension could end up making a difference when you’re deciding where to place your TV.
You may need to consider the depth of your TV in order to guarantee that it will fit an existing cabinet or stand. TVs are continually being redesigned to take up less space. These days, many flat screen models are less than 10 inches (25 cm) deep with a stand attached, and as thin as 3 inches (7. 6 cm) without. Older CRT televisions are much thicker. You will need to consider the depth with these more than any other TV. [5] X Research source
For maximum accuracy, round off your measurements to the nearest 1⁄2 inch (1. 3 cm). Jot the dimensions of your display space on a piece of paper and keep them with you when you’re shopping around for your new TV.
Having a few inches of extra space on all sides of your TV allows for proper ventilation, which can prevent performance issues caused by overheating. You’ll need to know your TV’s width and height if you intend to mount it on the wall. If you want to place it on a stand or in an enclosed cabinet, you’ll also need to factor in its depth. When mounting a TV to a wall, be sure to get a wall mount that is rated for the size and weight of your TV. You don’t want your TV to fall because it was too big for the wall mount.
If you’re going to be sitting about 72 inches (180 cm) away from your TV, for instance, a 60 in (150 cm) will provide optimum visibility.
Standard TVs tend to be older CRT models. They have an aspect ratio of 4:3. As such, they squeeze the picture into a square image with an overall smaller area, while widescreen TVs take advantage of their added width to display the full image in its proper dimensions. [9] X Research source A standard (4:3) TV and a widescreen TV could have the same diagonal screen measurement, but the picture would look quite different for each.
If you currently have a 40 in (100 cm) standard TV, you’ll need a widescreen TV with a screen that’s at least 50 inches (130 cm) to make sure your picture doesn’t get smaller. Standard TVs also have a smaller resolution than new widescreen HDTVs. So the same-size picture on a standard TV will have less detail than on a widescreen HDTV.
