When you buy a new LED screen, do you ever consider the display aspect ratios of the devices you check out? Many people simply overlook it and opt for the ones recommended by the store clerk or those they’ve researched online without diving into all their options. However, it’s better to learn about display aspect ratios and make a well-thought-out decision rather than simply following recommendations and starting with the definition of the term and what it really means. 

Defining Display Aspect Ratios

A display aspect ratio refers to the size of the display, represented by its width-to-height ratio (W:H). To simplify this, if the width is twice as long as the display’s height, the ratio is 2:1. That is the number you’d see depicted in aspect ratios, both for screens and video content. 

This ratio affects visual clarity and needs to match the aspect ratio of the video content for the images to remain crystal clear and vibrant. Pixel density also plays an important role in determining the image quality of the display. It is defined as the number of pixels found on the panel of the LED display, where more pixels mean clearer and sharper visuals.  

Display aspect ratios have evolved through the years as technology advances and innovations develop. The first video display had an aspect ratio of 2.59:1, which has undergone numerous changes, resulting in various display aspect ratios available today. 

Most Commonly Used Display Aspect Ratios 

Exploring the most common LED aspect ratios can help you decide which ones work best for you. You can learn so many things when comparing your options, like looking into the differences between 16:9, 21:9, and 32:9. 

The great thing about display aspect ratios applied to LED screens is that they can be customized whenever necessary. To get to know all the display aspect ratios you can use, let’s discuss each of them one at a time. 

Widescreen

A widescreen display aspect ratio has the proportion of 16:9 (or 1.78:1), which is popularly used in social media and streaming platforms. This aspect ratio is used by streaming services Netflix and YouTube. The 16:9 ratio is also used in video aspect ratio for the following devices:

• DSLR and Camera Recorders
• Smartphones
• Tablets

Cinematic Widescreen

The cinematic widescreen, with the aspect ratio of 21:9, is a type of widescreen that encourages better visual immersion. Also referred to as ultra-widescreen, it is the choice for artistic applications, including movies and interactive content. 

Similar to other display aspect ratios, they can also be adjusted to either 21.5:9 or 2.39:1. The video aspect ratio of 21:9 adjusts appropriately when shown on cinemas’ massive displays. This aspect ratio is also known as the following:

• Panavision
• CinemaScope – 2.35:1
• Anamorphic – 2.39:1

Square

With an aspect ratio of 1:1, the square is another common one used today, but not in screens. This aspect ratio reigned after the introduction and popularity of Instagram. The ratio points to the equal sides of the content, giving it a classic and elegant look. 

Vertical

Among all the display aspect ratios, vertical is the preferred one for phones. The 9:16 ratio fits perfectly with the shape and structure of smartphones. It’s also why it’s the preferred aspect ratio for social media platforms with a high percentage of mobile users, such as YouTube Shorts, TikTok videos, and Instagram Reels. 

Fullscreen

The 4:3 display aspect ratio refers to the standard full screen for most videos. It works well with archival footage and particular specifications, such as single speakers and a focused frame. In the 2000s, it was the most popular aspect ratio because it is the one most commonly used in video cameras and camcorders. Today, it is often used to avoid the reshaping and distortion of video content. 

Tall 

Among all display aspect ratios, tall has a portrait format with the measurements of 4:5. This has become a standard choice for mobile phones, considering the shape of smartphones today. 

On top of the display ratio, its video counterpart is also often used for portrait-mode videos and social media platforms, such as the following:

• Facebook
• Instagram
• TikTok

The format is better for video content that offers a more personal engagement, which is why it’s a good consideration for social media content. 

Wide 

The wide aspect ratio, like most display aspect ratios, can be customized for LED screens. With the measurements of 5:4, it is the opposite of the tall aspect ratio. It is only utilized in experimental cases because it is a problematic option for mainstream media production. 

Display Aspect Ratios Vs. Video Aspect Ratios

Are display aspect ratios the same as video aspect ratios? No, they are different in the sense that the former pertains to the aspect ratio of the tangible screen device, while the latter refers to the content’s video file. The former refers to the measurements of the pixels found on the LED panels, while the latter pertains to those encoded into a video file. 

The deal with display aspect ratios is that when you choose one, you’re limited to that aspect ratio. It is a hardware limit, so you won’t be able to adjust the pixels on the screen more than what it already has. 

Video aspect ratios, on the other hand, refer more to the content’s quality and not measurements of the hardware. They provide an idea of how high you can get in terms of the visual quality. 

After learning about the differences between display aspect ratios and video aspect ratios, the next step is to understand resolution and its role in display aspect ratios. Similar to video aspect ratios, resolution pertains to the video quality. Rather than the ratio, it provides a precise number of pixels used on the screen or the content, specifically in each frame. However, they are not the same. The table below is a good example that illustrates which display aspect ratios correspond to specific resolutions.

Display Aspect Ratio	Resolution
4:3	480p (640 x 480)	Standard Definition or SD
16:9	720p (1280 x 720)	High Definition or HD
	1080p (1920 x 1080)	Full High Definition or FHD
	2160p (3840 x 2160)	Ultra High Definition or UHD
1.9:1	2160p* (4096 x 2160)	4K Ultra High Definition or 4K UHD

In this table, a 4:3 display aspect ratio can work effectively with content that has a 480p resolution, while a 16:9 LED display can accommodate resolutions of 720p, 1080p, and 2160p. It means that you can only run videos with 480p resolution on a 4:3 LED display, and others may still run, but expect some distortion along the way. Meanwhile, a 16:9 aspect ratio can accommodate more content with higher resolution. This is precisely why it’s essential to select the correct display aspect ratio among the various options available. 

Figuring Out Which Among the Display Aspect Ratios To Use

Is there any way to calculate which display aspect ratio you need? Display aspect ratios are fixed, but the video aspect ratio is not. Choosing the correct proportion for your LED display and video content is essential to ensure you invest in the correct device. 

While you can always ask for recommendations, it’s better to learn how to choose which aspect ratio is ideal for you. For an easier way, you can use either a display aspect ratio calculator or an aspect ratio chart. 

Display Aspect Ratio Calculator

A display aspect ratio calculator is a practical tool that automatically calculates the aspect ratio of the monitor you need. To come up with the results, you need to consider specific factors, such as the following:

• Screen height
• Screen width

These two elements are sufficient to calculate the aspect ratio if you’re using a programmable calculator designed for that purpose. If you’re going to use an actual calculator to check out display aspect ratios, you’ll need to know the greatest divisor of the screen’s height and width. 

For instance, if the screen’s height is 480 and its width is 640, divide each by the greatest divisor, which is 160. 480 divided by 160 equals 3, and 640 divided by 160 equals 4. Arranged the numbers in the format “W:H,” and then that’s your aspect ratio. 

Aspect Ratio Chart

An aspect ratio chart is a helpful tool that allows you to immediately see which aspect ratio is ideal for your needs. The chart includes a list of display aspect ratios and the corresponding screen width and height compatible with them, along with the common resolution options for each. Generally, higher numbers indicate a wider display screen. 

If you don’t want to do any calculations, using an aspect ratio chart is the best option for you. Just look at the chart to know which display aspect ratio will work best for your needs and video content. 

Is Widescreen the Best Aspect Ratio for Displays?

When you hear the term “wide screen,” what does it really mean? Many will simply resort to the standard meaning, which pertains to a screen with a lengthy width. In terms of display aspect ratios, it often points towards 16:9, which is popularly used by streaming platforms, such as YouTube and Netflix. This is because it offers more horizontal space, providing more room for content viewing and making it perfect for watching TV shows and movies. 

Widescreen LED Displays 

Screens with 16:9 display aspect ratios often deliver an immersive viewing experience. They feature advanced viewing angles, enhancing the display’s visuals and providing an incredible viewing experience. 

To identify if your display is considered a “widescreen”, check the ratio of the screen’s width to its height. If the measurement is simplified into 16:9, then it’s a widescreen. If it ends up having the simplified proportion of 32:9, then it’s an ultra-wide display. Both 16:9 and 32:9 display aspect ratios can be referred to as widescreen. 

Widescreen LED Displays for Gamers

LED screens with display aspect ratios of 16:9 and 32:9 are ideal for gaming. These widescreens provide an immersive viewing experience that allows users to fully concentrate on the game and completely focus as if they’re in the virtual world. The wide screen offers a wider field of vision, which is an advantage to games that require users to pay attention to their surroundings (to be aware of potential threats and ambushes). 

In addition to that, they often go hand-in-hand with high resolution and HDR support, ensuring crystal clear and detailed visuals that will help you play better in games. Other accessories that often help improve the entire gaming experience are the following:

• Built-in speakers
• Adjustable stands
• VESA mounts

Are Widescreen LED Displays Better?

If you’re talking about gaming, widescreens are definitely better. They are also ideal for watching TV shows and movies, which is why most streaming services use the “widescreen” aspect ratio. To be more precise, here are some reasons why widescreen reigns supreme among all display aspect ratios:

• More gaming space – it accommodates more details into your view, which makes it a good option for gaming monitors
• Aids multi-tasking at work – even in the professional aspect, since you can view two web pages or applications side by side and multitask effectively without feeling constricted
• Supports high resolution visuals – Guarantees crystal clear visuals with the help of High Dynamic Range colors feature and high resolution

Conclusion

Display aspect ratios refer to the measurements of the screen’s dimensions. In proportion form, they are the display’s width and height, respectively. These aspect ratios define the dimensions of the screen, which affect the overall viewing experience of users. This is the reason why it’s important to understand them better. 

To guarantee worthwhile investment, understand which display aspect ratios work best for specific situations so that you can choose the ideal size ratio of your screen. Make sure you know the difference between video aspect ratios and how resolution plays a part in all of this.
