According to “Statista,” 11.7% of TV sales in 2019 are 65” in size, which’s an increase of 2.9% since 2018. When looking to purchase the best TV, many people may ask how wide is a 65-inch TV. This information can help consumers determine if a 65” TV is the right size for the prospective location where they would put it and the room size itself. How wide is a 65-inch TV? You may have to do some math.


  • A 65 inch TV screen measures 31.9 inches by 56.7 inches.
  • The guidelines for viewing distance suggest sitting 9.1 feet away from a 65-inch TV.
  • Some 65 inch TVs are available in LED, QLED, and OLED panel types.

What Are The Dimensions of a 65-inch TV?

When trying to measure the exact dimensions of a 65” TV, people use algebra or trigonometry to find the answer. The Pythagorean theory enables you to find the amount to multiply the diagonal of the screen to find the height or width. This calculation involves taking the square root of 16 squared plus nine squared.

The numbers that are squared and added together depend on the aspect ratio of the screen, specifically 16:9 units for widescreen TVs. Then, you divide sixteen by the square root to find the number to multiply the diagonal by to get the width and divide nine by the square root for the height.

In other words, for a widescreen TV, multiply the screen size, which represents the diagonal length across the screen, by 0.87157553712 to get the width and by 0.49026123963 to get the height. Thus, for a 65” TV, the height and weight of the screen come to 31.9 inches by 56.7 inches. To find the actual height and width of the TV itself, add several inches on each side for the bezel or edge of the TV.

Alternatively, when it comes to resolution, 1080p vs 4K image quality is a common debate. 1080p image resolution measures 1920 x 1080 pixels, providing good clarity and sharpness. Comparatively, the 4K image resolution is four times greater, boasting 3840 x 2160 pixels for unparalleled clarity, brightness, and color.

Room Size For a 65-Inch TV

The room into which the TV is going influences the prospective TV size apart from its actual size. This influence stems from the recommended viewing distance for the TV and the appearance of the TV itself. For example, for a 65” TV, the guidelines for the viewing distance suggest that you should sit 9.1’ away from the TV. The people who provide the guidelines for viewing distance use the ideal amount of your field of view and the angle at which the TV should be positioned.

Additionally, the appearance of the TV inside the room may also play a part in the resultant TV. You don’t want a TV that will look overwhelming in the room or one that is minuscule. If you have a smaller room then you can find out how wide is a 55-inch TV. As a result, some rooms require smaller TVs, and others often house medium or large TVs. If you require a smaller, 55-inch option, check out our Samsung UN55NU7100 review. For the average living room, a medium or large TV works better than a smaller one because of the size of the room and the number of people watching it. Mounting the TV on the wall will give you some more viewing distance as well versus putting it on an entertainment console.

Display Panels For 65 Inch TV

  • LED LCD – The liquid crystal display (LCD) with a light-emitting diode (LED) backlight is one of the most popular TVs on the market. After cathode-ray tube TVs became near-extinct, these LED TVs took over as the standard TV type. In addition, many of these TVs enable consumers to receive and decode digital signals.
    • There are several different panel lighting designs for LED TVs, including full-array, edge, and mini-LED TVs.
      • Full-array panels feature LED lights across the entire back of the panel, providing even light across.
      • The edge-lit panels feature lights along the edge of the display only, which does not provide even light across the panel.
      • Mini-LED TVs include smaller LED bulbs than the standard LED sizes, allowing the TV to have finer control over the highlights and shadows of the image.
  • QLED – Quantum dot LED (QLED) panels strongly resemble the LED LCD televisions that preceded them. The QLED TV features an additional film that the light passes through to create the image on the screen. This film houses quantum dots and increases the contrast within images for a more immersive experience. QLED TVs come with full-array, edge-lit, and mini-LED lighting.
  • OLED – Organic light-emitting diode (OLED) TVs showcase a completely different panel design. Although the name includes LED, these TVs are not LED-lit LCD panels. Instead, the panels include organic compounds that light up when electricity passes through them, a phenomenon called electroluminescence. OLED compounds generate their own light and do not require a backlight. As a result, OLED panels feature higher contrast between the brightest whites and darkest darks. This stunning picture quality will transform your viewing experience while watching movies. However, this panel type is less bright than some others because the compounds generate the colors. If this sounds like what you want your next TV to have, LG makes great OLED TVs, and you can read about a couple of them with our LG 65EF9500 TV review and our LG OLED65CXPUA review.
