#Understand aspect ratio and how it relates to TV size. Aspect ratio is the ratio of the display image’s width to its height. There's a difference in aspect ratio between older, standard TV models and newer, widescreen models. Most standard TVs use an aspect ratio of 4:3 for their screens. That means for every 4 inches of width of screen, you will have 3 inches of height. The newer widescreen TVs normally use an aspect ratio of 16:9. This means for 16 inches of width, you have 9 inches of height. | #Understand aspect ratio and how it relates to TV size. Aspect ratio is the ratio of the display image’s width to its height.

#*Even though a standard (4:3) TV and a widescreen (16:9) TV could have the same diagonal measurement, such as a 32-inch screen for both, the total area of the screen would be different. The standard TV will have a bigger screen area and the image will be more square, while the widescreen TV will have a more horizontal image. | #*Even though a standard (4:3) TV and a widescreen (16:9) TV could have the same diagonal measurement, such as a 32-inch screen for both, the total area of the screen would be different.

#Perform a simple calculation to match the screen size of a standard TV to that of a widescreen TV. If you currently have a 4:3 TV and you want to continue watching 4:3 on a widescreen TV, multiply the diagonal length of the older TV model by 1.22. The result would be the diagonal screen size that the widescreen TV would have to be to match the old model. | #Perform a simple calculation to match the screen size of a standard TV to that of a widescreen TV.

#*Say you have a 40 inch (102 cm) TV with a 4:3 aspect ratio, but you're thinking about upgrading and you don't want your screen size to get smaller. You'd need to get at least a 50 inch (127 cm) screen to view in 4:3 without your picture getting smaller. That's because 1.22 x 40 = 49. Since 49 inch TVs are generally not made, you'd need to go up to 50 inches (127 cm). | #*Say you have a 40 inch (102 cm) TV with a 4:3 aspect ratio, but you're thinking about upgrading and you don't want your screen size to get smaller.
