To understand the answer, it is essential to remember a few measuring standards and some jargon, as well as what is measured to get 24 inches.


  • TV screens are measured across the diagonal of the screen.

  • Products listed as “24” class” are not usually exactly 24 inches, and this difference may be up to half an inch.

What Do TV Screen Sizes Represent?

Manufacturers determine the screen size of a TV by measuring along the diagonal of the screen. The frame of the TV, also known as the bevel, is not included in this measurement. In the United States, TV screens are referred to by the size in inches, which is vital to remember if you usually measure things in centimeters.

If a TV screen’s description has the size followed by the word “class,” then it may not actually be the size it states. Class refers to TVs that are about the size listed. The difference between a TV size and what is listed at in this case should be within half an inch of the actual size of the display. The half-inch difference can be either bigger or smaller, so size does not always mean that the screen is smaller. If the class difference extends past ½ inch, then the actual size of the screen legally must be listed in the product information. However, some manufacturers include the actual size if the distance is less than ½ inch.

Common Aspect Ratios For a TV

To determine the approximate size of the screen width and height, consumers may want to consider the most common aspect ratios for TVs. These two aspect ratios are 4:3 and 16:9, with the first number being its width and the latter being height. Prior to the introduction of widescreen TVs, the most common aspect ratio was 4:3. Since widescreen TVs became popular, manufacturers typically utilize an aspect ratio of 16:9.

To determine the approximate space the TV would take there are certain formulas to use. However, these formulas are listed online, and there are sites that let you input the aspect ratio and the diagonal. For a 24” TV with an aspect ratio of 16:9, the height of the viewing area is about 11.7 in. while the width is roughly 20.9 in. If you are considering whether the TV will fit in your space, make sure to add a few inches along the edges for the bezel.
