What are the Dimensions of a 45 Inch TV?
The actual dimensions of a 45-inch TV are 39 – 41 inches x 22 – 24 inches x 1.5 – 3.5 inches (W x H x D). Mind that these ranges are general dimensions, with variations between different models from various brands. Let’s explore these measurements in-depth and find out their differences with respect to stands and bezels:
Width of 45-inches TV
The average width of a 45 inch TV from most brands is around 39.1 inches. However, slight variation can exist due to the presence of bezels. In fact, bezels can contribute up to 2 inches in width. Keeping this aspect in mind, we can say that the width of your 45-inches TV falls in the range of 39 – 41 inches.
How to Measure the Width of a 45 Inches TV?
You can find the width of a 45-inches TV by using a tape measure, extending it from the left side to the right side. Keep in mind to factor in bezel size to get precise measurements.
Alternatively, you can use the given formula to find the width of your television:
Considering the diagonal measurement of 45 inches, the above formula predicts the width to be around 39.2 inches.
Height of a 45-Inch TV
The height of a 45 inch TV is roughly around 22 inches. This is the distance between the top edge and the bottom edge of the TV. If we consider the bezels, you need to put an increment of at least 0.5 – 2 inches in the height, giving you dimensions of 22 – 24 inches.
Similarly, some models may even have a built-in stand of up to 5 inches. Therefore, we can assume the height of a 45 TV inch with a stand up to 27 inches.
How to Measure the Height of a 45 Inches TV?
You can calculate the height with a tape measure by stretching it from the top edge to the bottom edge. On the other hand, you can use the given formula to find the relevant dimensions:
By using the diagonal measurement as 45 inches, the above formula will also yield a height of 22.06 inches, without any bezels or stands.
Depth of a TV with 45-inches Dimensions
The average depth of a 45-inch TV can be around 3 inches. However, some models are as thick as 1.5 inches. Therefore, the exact measurements depend on the type of model.
And if we want the calculations while considering the stand, the dimensions could go up to 10 inches. Take an instance of Hisense H45N5750 with a depth of 8.46 inches while counting in the stand. Therefore, we can say that the depth of a TV falls in the range of 1.5 inches to 10 inches.
How to Calculate the Depth of a 45” TV?
You can find the depth of a 45-inch TV with the help of a measuring tape by placing it against the sides of the device. You also need to think about the stand to get the precise dimensions.
Screen Size of a 45-Inch TV
The screen size of a 45” TV is 45 inches. Remember that the screen dimensions are always measured diagonally to find the optimum TV size. Further, TVs can come in various ratios, such as 16:9 and 4:3. Both formats can have different sizes. However, their average diagonal measurements would always be 45 inches. Note that you also have to chew on the bezels while finding the screen size.
Weight of a 45 Inches TV
The weight of a 45” TV is around 8 pounds to 21 pounds. However, some models, such as the Megrahdr 45 Inch 4K UHD LED TV, can even exceed and weigh around 53 pounds.
Consult the user manual or ask an expert to find the exact weight. This parameter is essential if you are planning to move the TV around or mount it.

45-Inch TV Dimensions for Different Brands
Let’s explore the TV dimensions of different brands with 45-inch measurements:
Samsung 45 Inch TV Dimensions
You may be surprised to learn that there is no single model from Samsung with 45 inch dimensions. This is because it is a not-so-common model and is not in much demand.
Sony 45 Inch TV Dimensions
Likewise, it is hard to find Sony TVs with 45 inches. Two models come near to the mark of 45 inches:
1. Sony Bravia 3D:
Sony Bravia 3D has a screen size of 44.5 and dimensions of 42.52 inches x 25.98 inches x1.5 inches (W x H x D).
2. Sony KDL-46XBR45:
Sony KDL-46XBR45 has a screen size of 46 inches, and overall dimensions are 49.57 inches x 26.97 inches x 5.67 inches (W x H x D).
Hisense 45 Inch TV Dimensions
Hisense is a Chinese manufacturer that has one 45 inch model, known as Hisense H45N5750. The dimensions are: 39.88 inches x 22.87 inches x 2.76 inches (W x H x D).
LG 45 Inch TV Dimensions
LG offers monitors that are 45 inches in size. The average dimensions of these monitors without the stand are 39.1 inches x 17.9 inches x 8.5 inches (W x H xD).
LCD vs LED 45-Inch TV Dimensions
When it comes to the dimensions of LCD vs. LED, most people get confused. However, a TV’s resolution doesn’t impact its measurements. However, a trend has been seen that modern TVs are shifting towards LED, OLED, or QLED technology.
Plus, these televisions also have thin bezels. Therefore, you may see a slight difference of 1-1.5 inches in the width as well as the height of the latest models.
Similarly, any 45 inch smart TV will have the same measurements as non-smart televisions, albeit the only difference will be in features. A smart TV comes with built-in internet connectivity, making it a bit different from simpler models.
Visual Comparison of 45 Inches TV with Common Objects
If you need to get a TV box with forty-five-inch dimensions and are struggling to get an idea, here is a rough visual comparison. A TV with such a big size would be a little wider than a standard sofa set and a bit taller than a large suitcase. In other words, the height of a small dog like a Beagle, standing on its hind legs, would be equal to the screen size of the TV.
What is the Optimal Viewing Distance for a 45-Inch TV?
The optimal viewing distance for a 45 inches TV is 5 – 6 feet (60 inches, 152.4 cm, 1524 mm, 1.5 m) with a 30-degree viewing angle. This distance is recommended so that you enjoy the best possible quality without hurting your eyes.
You can also measure the sitting range by yourself. As per Samsung, simply multiply the screen size by 1.2 times, and you will have the optimal distance. In this case, we will get a distance of 54 inches or 4.5 feet.
THX Guidelines
THX recommends a distance where the screen covers 28 – 40 degrees of your field of view. This length can be obtained by multiplying the size by 1.2 – 1.8 inches. For a 45-inch screen, the sitting length would be 4.5 – 6.75 feet from the TV.
SMPTE Guidelines
SMPTE, or Society of Motion Picture and Television Engineers, suggests that you should sit where the screen can occupy 30 degrees of your field of view. To get these measurements, multiply the TV size by 1.62, and you’ll get an answer of 6.1 feet.
Variation in Distance on the Basis of Viewing Resolution
Sony recommends considering both sizes and resolutions to find the optimal viewing distance. Sitting too close will hurt your vision, and sitting too far away may disturb the whole watching experience.
- For a 4K TV (3840 x 2160 pixels), you should sit a distance of 1.5 times the screen size or the point where the screen covers 30 – 40 degrees of your vision. This would be equal to 5.625 feet for a 45 inch TV.
- For HD TV (1920 x 1080 pixels), the distance is 3 times the diagonal screen size. This will yield a distance of 11.25 feet of the distance for a size as big as 45 inches.
- For an SD TV (720 x 576 pixels), the distance is 6 times the diagonal size of the TV. This will give you a viewing distance of 22.5 feet from the screen.
Space Requirements for 45 Inches TV
As we know the dimensions as well as the optimal sitting distance for a 45 inch TV, what’s the optimal space requirement for this big-size TV? Here are some key factors for your consideration:
- The best room size to accommodate this size should be in the range of 14′ x 14′ (4.3m x 4.3m) and 16’ x 16’ (4.9m x 4.9m).
- The ideal placing space (wall or stand) should have dimensions such as 42 inches in width and 25 inches in height.
- For ventilation, you need to leave 3 inches of depth behind the TV, 2-4 inches of clearance on both sides and 1 inch of space on the top side.
Furniture Placement for 45-Inches TV
If you are planning to place your 45-inch TV on a stand or a media console, you should have exact dimensions for perfect furniture placement. Find out the following tips to quickly learn about it:
- The stand should have a width of more than 41-42 inches, and it should have a depth of 10 – 13 inches to handle the TV.
- The height of the stand should be 20 – 24 inches to get an ideal eye-level view.
Wall Mounting
To mount a 45-inch TV, the wall should provide a clearance of 42 x 25 inches (W x H). Install the mount at a height of 42 – 48 inches for an eye-level view. Ensure that the wall mount can lift a weight of at least 50 pounds (consult the user manual or take the help of an expert).
Get a VESA-compatible mount, as they can adjust most of the TV sizes. During installation, the mounting pattern should be 400 mm x 400 mm (16 inches) between the mounting holes for a good placement.
The following are common types of wall mounts:
- A fixed mount provides a clean look and no movement.
- Tilt mount allows slight movement in upward and downward directions.
- Full-motion mounts offer a greater degree of movement and grant you a view on multiple sides.
Installation Tips
You can either install the TV on your own or you can get help from an expert (recommended for safe and clean installation). Keep in mind the following points for the best results:
- Safety: Safety should be paramount. Ensure that the stand as well as mounts are strong enough to support the weight.
- Aesthetics: Use a cable management system for a clean and aesthetic look. Mind the clearance between the wall/surrounding furniture and the TV for a neat appearance.
- Fireplace Placement: You can install the TV on a fireplace. However, keep a distance of at least 3 feet to avoid heating, or you can install a mental.
- Room Layout & Environment: If you have an open-plan space, find the zoning areas for TV placement. Ensure that there is direct sunlight to avoid glare, as well as take care of echo and noise distortion. For closed rooms, wall mounting is the best option to save space. Choose layouts that don’t block the natural flow of the space.
Transporting a 45-inch TV
45 inches is a big size. Measure the doors, stairs, and hallway so that you can seamlessly carry the TV to its destined position. Use the original packaging for movement and a dolly/trolly to move around. You should use a carrier truck to transport the TV. Place it like a mattress with the screen in the upward direction.
Things to Consider Before Buying a 45 Inch TV
Investing in a big size like 45 inches is not an easy decision. Therefore, it is suggested that you should make a sound plan in advance to avoid any issues. Following are the things that you should consider while getting a TV of this size:
- Nowadays, smart TVs are in trend. Get a TV that has features like built-in internet connectivity for online access, HDMI 2.1 for fast gaming, and HDR compatibility.
- If you have kids or pets, use furniture straps to avoid tipping off the TV stand. Be sure to leave some surrounding space for speaker bars or consoles.
- Go with models that have Energy Start or similar certifications to save your power consumption and bills.
