In many cases, you need to put the new TV in a narrow space such as a closet or between any two objects, so the requirement is how to measure TV size. Measuring your TV’s size is not that difficult, and with a little information below, you can find the fastest and most effortless way to measure your TV.
How to measure tv size?
In what units is tv size measured?
You may not know that TV sizes in different parts of the world are measured with varying unit systems. These units can be the standard measurements of length, such as centimeters, dm, or units of volume such as cubic meters and cubic centimeters.
However, the general normative system in the world has quite a clear consensus. Specifically, the typical reference system for size parameters of electronic products such as TV lice is “Inches”. In which, 1 inch = 1 ” = 2.54 cm. Thus, with the above concept, you can easily convert it to your standard unit. More importantly, the 55-inch, 49-inch, or 43-inch TV numbers demonstrate the diagonal length of that TV’s display.
General procedure for measuring TV screen size
Step 1: Measure TV Size
Measure the TV diagonally.
Measuring TV screens diagonally is the standard method that many TV manufacturers around the world are using. Many people mistakenly assume that the 32-inch number on a TV’s label is the TV’s width.
But exactly it would be the diagonal length of the device calculated from the bottom corner of the television to the top opposite corner.
Measured within the screen
Not many can get this done correctly. When calculating the size, they start at one end of the bezel and go all the way to another, resulting in an incorrect size measured.
Instead, you need to measure the TV screen diagonal from an inner corner of the screen to the opposite corner in a diagonal direction, ignoring the TV bezel because this bezel is always longer than the actual size of the screen.
Step 2: Place the TV in a Narrow Space
All you need to do is measure the width, length, and thickness of the TV (including the bezel). It is almost impossible to estimate the amount of space required for it within the narrow available spaces without specific measurements.
Keep it in mind that the storage space should be slightly larger than the TV itself size. For example, if you want to buy a 46-inch set, the TV’s width will be about 113 cm and the vertical equivalent of about 63.5 cm.
In theory, you need to leave enough space for this gadget. However, the external senses will be very cramped, thus compromising the importance of aesthetics. Therefore, you need to allocate more space to set up this TV.
Step 3: Relationship of screen ratio to TV size
Understand what screen ratio is and its relationship to TV size
According to TV Mates, The aspect ratio of the screen is the horizontal ratio to the vertical direction of that TV. Older TVs bear a big difference in screen aspect ratio compared to the new generation curved-screen TVs.
Most products manufactured years ago share a standard aspect ratio of 4: 3. This means that if a TV is 4 inches wide, its vertical length will be 3 inches. TVs with more modern screens will have an aspect ratio of 16: 9, which means that the width to height is 16/9.
All you need to do is determine the aspect ratio of the TV you want to measure. Then, take measurements according to your available space, and you’ll find the right TV size.
For example, you want to buy a new TV with an aspect ratio of 16/9. If the width of the space you want to set V is 30 inches, the height of this space cannot be less than 54 inches. This is a step to coordinate with conventional TV diagonal measurement, helping you to control this problem.
Do a simple calculation to keep the aspect ratio of the screen.
Performing this calculation is relatively simple. If your old TV has an aspect ratio of 4: 3 and you want to switch to a new one but still want to keep this perfect aspect ratio, multiply the old TV’s diagonal length by 1.22 to be the size of the TV to be purchased. For example, you have a 40-inch TV with an aspect ratio of 4: 3. If you still want to keep this ratio, do the following calculation: 1.22 x 40 = 49. Therefore a 49 inch TV is the one you need to buy.
Step 4: Calculate the viewing distance according to the TV screen size
After you have the TV size, you will need to take the final step of measuring the relationship between the distance from the viewing position and the TV size. Although it is the last step, which many people ignore because it is not essential, it has a lot to do with your eye health.
If the viewing position is too close to the big screen TV, your eyes will weaken and may be nearsighted, see the following guide for the exact ratio of the distance from the sitting position to the TV and its overall size.
| Screen | Distance sitting |
| 27’’ | 1-1,7m |
| 32’’ | 1,2-2m |
| 37’’ | 1,4-2,3m |
| 40’’ | 1,5-2,5m |
| 46’’ | 1,7-3m |
One note is that the sitting distance in the table above is the smallest number you need to ensure. You need greater distances to enjoy the most comfortable TV viewing for long periods.
Conclusion
Finally, measuring the parameters of a TV is necessary in many cases, especially in narrow space conditions, and it is essential to balance many other factors that influence.
