40 inch tv dimensions

Did you know that the size of a 40-inch TV varies across different brands and models? They may seem similar initially, but you’ll find slight differences in the actual width, height, and depth when you go into the details.

This article will show all the factors affecting the 40-inch TV dimension. The three important measurements that form the physical size, as well as the elements to consider before real shopping, are all discussed here.

Dimensions of the 40-Inch TVs


How big is a 40-inch TV? This is one of the first questions that would pop up in your mind when planning to buy this television size for your room.

For a glimpse, the 40″ TV’s average physical size is

  • In inch: 34.9 x 19.6
  • In cm: 88.65 x 49.79
  • In mm: 886.5 x 497.9

The TV dimensions by size of a 40-inch TV are the totality of the three key measurements: the width, height, and depth influenced by the presence and absence of a stand or mount of the chosen TV.

1. The Width


A 40-inch flat-screen TV’s width is taken horizontally from one side to the other, including the bezels or frame in its measurement. Most newly emerging 40-inch monitors typically have frame support or bezels ranging from 0.5 to 1 inch.

As stated above, the typical width for a 40-inch TV is 34.9 inches.

2. The Height


On the other hand, the height of the 40-inch TV may affect the fitting during installation.

This vertical measurement increases when a stand is connected to the TV base. When you happen to choose a TV with feet on both sides, expect that this may take more space than those that use a central stand.

The average height you will find in most 40-inch TV models across different brands is 19.6 inches.

3. The Depth


The depth of the TV is measured from the back to the front and can be influenced by the type of mount.

When you plan to recess TV on the wall, consider leaving additional space for the support and a little bit of space on the sides for ventilation.

Comparison of Dimensions Across Different Brands


As you explore different brands of 40-inch TVs, you may notice slight variations in dimensions. These differences can be attributed to design choices and variations in manufacturing processes.

Hence, it’s always a good idea to compare the different models within the same advertised size category to be aware of the TV’s actual size that is perfect for your space.

Factors to Consider When Choosing a 40-inch Tv


There are a few general rules for average consumers to be aware of before investing in a 40-inch TV. First, consider a TV based on room size.

Images and motion pictures on large-screen TV may appear distorted when you sit too close to them because the room is too narrow for the television you bought.

Small ones in an enormous room also strain the eyes as it is a struggle to watch from a distance.

  • A 40-inch TV finds a perfect place in a 10×10 ft and 10 x 11 ft room size. These rooms accommodate the recommended viewing distance comfortably without the feeling of being compact.
  • For gaming usage that requires an immersive experience, a viewing distance of approximately 4 feet which falls under the recommended 40-degree view angle, is great, and for leisurely watching, 5.5 feet (30-degree angle) with no obstructions to the view is more recommended.
  • Furthermore, choosing higher resolution such as 1080p, sometimes termed Full HD, and the latest 4K or Ultra HD displays sharper images and more explicit videos.
  • Whether you have different types of TV, such as OLED or LED, enjoying your watch in a 16:9 aspect ratio leaves a great viewing experience without worrying about eye fatigue.

Frequently Asked Questions

Comparisons with Other TV Sizes

The measurement of a 40-inch TV is best for a medium-sized room. It looks particularly big for small rooms compared to small screens, such as the 32-inch TV.

In a spacious living room, it seems like a dwarf screen compared to a 70-inch TV that is proportionate to the size of the room.

Relationship Between TV Size and Viewing Distance

Going beyond or below the recommended viewing distance of a 40-inch TV compromises your viewing experience. When you watch in close proximity, you might find it too overwhelming after a short time.

Watching TV from a long distance can strain your eyes as you struggle to catch the images and motion on the screen. It also lessens the thrill present in watching at the recommended distance. Hence, staying on the 4-5.5 ft distance is the best option.


It is essential to thoroughly understand the 40 inch TV dimensions to ensure you choose the ideal television that meets your needs. By considering crucial factors such as room size, viewing distance, resolution, and aspect ratio, you can truly elevate your entertainment experience.
