Defining & Calculating Aspect 16:9 Aspect Ratio

In screen displays such as TVs, monitors, or commercial LED displays, aspect ratio simply refers to the ratio of a screen size in terms of its length and height, or x:y ratio.

So, a 16:9 aspect ratio simply means that the unit ratio between its width and height is 

16:9. In simple terms, for every 16 units of the screen width, the screen’s height is 9 units. 

From this explanation, you can tell that the aspect ratio 16X9 screen is a horizontal rectangular screen. This aspect ratio is meant to provide viewers with an enhanced horizontal viewing experience.

Aspect Ratio Calculation

Calculating your screen’s aspect ratio is easy! Here are some of the techniques you can use.

Method 1 – Measuring Your Screen’s Width and Height.

Simply measure your screen’s width and height in inches then divide the measured width by the height to get its aspect ratio.

Method 2 – Using Your Screen Resolution

Alternatively, if you already know your screen’s resolution, dividing its horizontal pixels by the vertical pixel gives you its aspect ratio.

For instance, if your LED screen has a resolution of 2560 pixels X 1440 pixels, simply divide the horizontal resolutions in pixels with the vertical pixels. That is, 2660/1440. This gives you a 16:9 aspect ratio 

Method 3 – Using Diagonal Measurements 

If you are a math lover, this method will be fun! All you need to do is get your screen’s diagonal measurement and use the Pythagorean theorem to calculate your screen’s width and height. You then evaluate the aspect ratio by dividing your calculated width by the height.

Method 4 – Using Online Aspect Ratio Generator

Another option is visiting an online site with Aspect Ratio Calculator. Simply input your screen’s width and height to get its aspect ratio. This is important especially when you need to resize your images or videos for screen display. 

What Is The Importance of an Aspect Ratio?

Here are some of the general reasons why your knowledge of the 16:9 aspect ratio is important.

16: 9 Aspect Determines Screen Size and Shape

Because aspect ratio defines the unit relationship between a screen’s width to its height, it means it is a key element when describing your screen size or shape.

For instance, an aspect ratio of 16:9 describes a horizontal and wider screen. If the aspect ratio is 9:16, the screen will then be described as vertical and taller.

Aspect Ratio Ensures correct display of Screen Images

If images or texts are viewed on a screen with the right aspect ratio, they will displayed with their correct width and height ratios. 

So, you will not miss any sections of the image. The displays will also be free from distortion as no side of the image or text will be abnormally stretched or compressed

Again, with the right aspect ratio, both the quality and clarity of your displays will be enhanced.

What Makes Aspect Ratio 16:9 Popular?

As a human being, you will naturally find it easy to view scenes horizontally as opposed to vertically! This makes the 16X9 a better screen format for TV displays and LED screen displays.

Aspect Ratios and Resolutions – What’s The Difference?

Screen Resolutions

You may be wondering if aspect ratio and screen resolution refer to the same thing. Not at all. While both your screen’s aspect ratio and resolution determine the quality and clarity of your displays, these two terms have different meanings. 

Aspect Ratio: As already stated, the aspect ratio is all about comparing the unit measurements of a screen with its unit height. The expression must be in ratio form such as 16:9. 

Remember, this can be simplified by dividing both sides by the vertical unit. 

For instance, a 16:9 aspect ratio can be expressed as 16/9:9/9. This approximately translates to an aspect ratio of 1.78:1

Because aspect ratio determines the size and shape of your screen, it means the wider your screen is, the better viewing experience you will enjoy!

Screen Resolution: The screen resolution, however, refers to your display screen’s total number of both horizontal and vertical pixels. 

For instance, a resolution of 1920X1080 simply means the screen has 1920 horizontal pixels and 1080 vertical pixels.  

So, to get the total pixels, simply multiply the horizontal pixels with the vertical. In this case, for this resolution, the total pixels are 1920X1080 =2,073,600 pixels

Note 1: Aspect ratios can be at different resolutions. For instance, a 16:9 aspect ratio screen can either be a laptop screen with a resolution of 1920X1080, or an LCD screen resolution of 1366X720

Note 2: Once you know a screen resolution, you can easily evaluate its aspect ratio. You do this by simply expressing the resolution values as a ratio. 

For example, a resolution of 1920X1080 becomes 1920/1080 or 1.78, or simply 16:9

Note 3: Display screens with higher resolutions and wider aspect ratios allow you to have a clearer and better view of image details than those with lower resolutions with narrow screens.
