40 Inch TV Dimensions

Is a television with a screen measuring 40 inches the ideal size for the room it will be placed in, or do you need a larger or smaller screen? Let’s have a peek.

In the following paragraphs, you will find information that will provide you with the real 40 Inch TV Dimensions. In this article, I also have given data by analyzing the screen sizes of popular TV models.

There are measurements for the TV itself, not including any stand or mounting hardware. The majority of TV bezels have a side profile that is anywhere from 0.5 to 1 inch in depth. When you factor in the bezel, it will add an additional inch to your TV.

What Are the Dimensions for a 40-inch TV?

The actual dimensions of 40-inch flat screen TV with a 16:9 aspect ratio are:

  • Width: 34.9 inches
  • Height: 19.6 inches
  • Thickness: 4 inches

These calculations do not take into account the stand. After you add the stand, the depth of the television will increase to something in the neighborhood of 8 inches. This number is subject to some degree of variation.

How Big Is a 40 Inch TV?

A 40-inch TV may appear small in a large room and is less noticeable, making it a good option when you don’t want the TV to be the center of attention. When placed on a stand for the TV, it may be slightly above waist height and ideally, the center of the screen should be at eye level for better viewing experience. A higher stand can help achieve this.

How to Measure a 40-inch TV?

To measure a 40-inch TV accurately, you will need either a ruler or a tape measure. Here are the steps you can follow:

  1. Determine the diagonal length: Measure the distance from one corner of the screen to the opposite corner diagonally. This will give you the diagonal length of the TV.
  2. Determine the height: Measure the vertical distance from the top to the bottom of the screen. This represents the TV’s vertical resolution.
  3. Measure the width: Measure the horizontal distance from the left to the right side of the screen. This represents the width of the TV across its horizontal axis.

You can describe the size of your TV as 40 inches based on the diagonal length of the screen.

What is Mean the Size Class in 40-inch TV?

It is possible that the TV size you find may not match the TVs labeled with the word “Class.” TV companies use a predetermined standard by adding the word “class” after the screen size to market their TVs. If the diagonal measurement of the TV is within 0.5 inches of 75 inches, then the word “Class” is used by different brands and manufacturers. Therefore, it is important to check the color accuracy when searching for a TV with the word “Class” in its name.

Color accuracy is a crucial factor to consider when selecting a TV size. Hence, it is essential to ensure that the TV you purchase meets the color accuracy standards you are looking for. However, sometimes the difference in size may be more than half an inch, even though it is not always less. In such cases, the TV’s actual size may not match your estimation based on the description. Nevertheless, since the difference is just half an inch, the estimates should not be significantly off.

40-inch TV Screen Resolution

The resolution of a 40-inch TV can vary depending on the model and manufacturer. However, most 40-inch TVs these days have a resolution of 1080p (1920×1080 pixels) or 4K (3840×2160 pixels).

A 1080p resolution is suitable for most types of content, including TV shows, movies, and gaming. It provides clear and sharp images and is a popular choice for mid-range TVs.

On the other hand, a 4K resolution offers four times the amount of pixels compared to 1080p, which results in incredibly detailed and crisp images. It is especially suitable for larger screens like a 40-inch TV, as the higher resolution allows you to sit closer to the screen without seeing any pixelation. However, keep in mind that not all content is available in 4K, so you may not always be able to take advantage of this resolution.

What Size TV Should I Get?

The optimal TV screen size depends on various factors, including the size of the room, the distance between the TV and seating area, and personal preferences.

A general rule of thumb suggests that the TV screen size should be about one-third of the viewing distance. For example, if you are sitting 6 feet away from the TV, a 40-inch screen would be suitable. However, if you have a larger room or prefer a bigger screen, a larger TV may be more appropriate.

As a rough guide, TVs ranging from 19 to 24 inches are recommended for viewing distances of 3 to 4 feet, while TVs ranging from 60 inches or larger are suitable for distances of 10 feet or more.

Ultimately, the best TV size for you depends on your viewing space and personal preferences. Visiting a store that offers a range of TV sizes can help you make an informed decision.

How Big Should the Room Be for the 40-inch TV?

The size of the room is not the only factor to consider when choosing a TV size, as the ideal screen size also depends on the viewing distance. However, as a general guideline, a 40-inch TV is suitable for a medium-sized room, such as a bedroom or small living room, where the viewing distance is typically between 6 and 8 feet. If the room is larger, you may want to consider a larger TV size to ensure that the screen is easily visible from your seating position. Similarly, if the room is smaller or if you will be sitting closer to the TV, a smaller screen size may be more appropriate.

It’s important to note that the size of the room is only one aspect to take into account when selecting the appropriate TV size. Other crucial factors to consider are your personal preferences, the resolution of the TV, and the kind of content you’ll be watching.

What Is the Correct TV Viewing Distance and Angle?

Viewing distance:

A general rule of thumb for selecting the appropriate screen size of a television is to make it about one-third the distance between the TV and the seating area. For instance, if your viewing distance is 6 feet (72 inches), a 40-inch TV would be a suitable choice. However, if you have a larger living space or prefer a bigger screen, consider purchasing a larger TV size.

To provide a rough idea, recommended TV sizes based on viewing distance are:

  • 19 to 24 inches for a distance of 3 to 4 feet
  • 24 to 39 inches for a distance of 4 to 6 feet
  • 40 to 49 inches for a distance of 6 to 8 feet
  • 50 to 55 inches for a distance of 8 to 10 feet
  • 60 inches or larger for a distance of 10 feet or more

Viewing angle:

The term “viewing angle” refers to the widest possible vantage point from which a television may be seen without the picture becoming distorted or dull. If a number of people will be seated in a variety of locations across the room while simultaneously viewing television, this is an essential aspect to take into account.

The viewing angle for televisions with a screen size of forty inches is normally somewhere in the neighbourhood of thirty degrees, however this might vary depending on the technologies used by the television. The viewing angles offered by OLED Televisions are the most expansive, but it might be difficult to locate a 40-inch model equipped with this technology.

It is important to keep in mind that the recommended viewing distance and angle are simply rough suggestions, and that individual preferences may vary depending on the particular aspects of the viewing environment.


What is the diagonal of TV screens with 40 inches?

How much room do you need for a TV that is 40 inches in size?
The viewing distance as well as the layout of your room will decide how much space you will need for a television that is 40 inches in size. As a general rule, a distance of between 4 and 6 feet (or about 0.3 and 1.8 metres) is considered to be an appropriate viewing distance for a 40-inch television.
Will a 40-inch TV fit in my car or SUV?
The answer to this question depends on the make and model of your car or SUV and the size of the TV. A 40-inch TV will typically have dimensions of around 34.9 inches in width and 19.6 inches in height. A 40-inch box dimensions are usually 4 to 6 inches larger in all dimensions compared to the TV, regardless of whether the screen is flat or curved.
You should measure the dimensions of your car's trunk or backseat area to see if the TV will fit. Additionally, you may want to consider folding down the backseat or removing it entirely to make more space for the TV. It's always a good idea to check the TV's packaging for its dimensions and to plan accordingly.
What is the typical weight of a 40-inch TV?
A 40-inch flat-screen TV typically weighs between 15 and 40 pounds (6.8-18 kg), making it much lighter than older TV models. This makes it easy to mount on a wall or place on a TV stand. However, the weight can vary depending on the type of stand. Central stands, which are larger and heavier, are used to keep the TV stable, while side stands can make the TV lighter.
It's important to note that the weight of a TV can also depend on the type of display technology used (such as LCD, LED, or OLED) and the type of stand or mount it comes with. It's always a good idea to check the specifications of a specific model to get an accurate weight. The weight of the TV is usually listed in the product specifications provided by the manufacturer.


If you are looking for a screen that is a little bit more stunning than a 32-inch screen but are on a budget, a 40-inch TV is a wonderful option to consider. Due to the fact that the screen size is being gradually phased out, you will not be able to get the most recent features; nevertheless, this should imply that you should be able to obtain a reasonable price tag.

Nonetheless, they will make the area seem cramped in the majority of living rooms and dens; thus, you should think about purchasing a larger one if you have the option to do so and the necessary space. Nonetheless, when seen from a closer distance, such as in a child’s bedroom or when the television is placed on a desk, the size of these televisions may still seem to be rather remarkable.
