What is Aspect Ratio? | When to Use Different Width to Height Screen Proportions

Table of Contents

A monitor is an electronic display unit made of a screen, circuit system, and a plastic casing enclosing the circuit system. Aspect ratio definition is the ratio of a monitor's width to the height where the first number represents the width and the second number represents the height. Aspect ratios are used in TV, monitors, cameras, printed images, digital images, and many more. There are several aspect ratios in relation to monitors, photos, and cameras. Common aspect ratios include 4:3, 16:9, and 21:9. A 21:9 aspect ratio means the width is 21 and the height is 9. The aspect ratio can also be symbolized by a single number (without a ratio). For instance, a 1.78 aspect ratio is the same as 16:9. You divide 16 by 9 to get 1.78. 

Aspect ratios are used to mean different things. For instance, a 1:1 aspect ratio means a square. You'll likely find this aspect ratio in social networks like Instagram. Despite each aspect ratio having its benefits, the 16:9 aspect ratio has more comprehensive applications than any other aspect ratio. Moreover, you're more likely to encounter this aspect ratio in many monitors. 

What Does Aspect Ratio Mean?

Aspect ratio is the width of an image in relation to its height. It commonly comes in two numbers that you separate using a colon. For instance, you can have 16:9 and 1:1 aspect ratios. The first number always represents the image's width, while the second one represents the height of the image.

Aspect ratios are understood ways of describing an image's general shape. Aspect ratios enable designers to carry out changes to the shape of an image depending on a project's specific needs. An image's aspect ratio can change based on the print or platform you present the graphic.

Knowing the different aspect ratios and adjusting accordingly will help you develop incredible content irrespective of where the image is to be used. Applying the correct aspect ratio is vital in ensuring that your images are displayed without cropping, stretching, or resolution loss. Maintaining the same aspect ratio of the image is an essential aspect of design.

Knowing the correct aspect ratio is essential as there are so many standards. The standard aspect ratio for one device may not be standard for another device. For instance, software developers creating content for both PCs and Smartphones should consider that a laptop screen has a different aspect ratio from a Smartphone. For example, most iPhones' most common aspect ratio is the 9:19 vertical aspect ratio. On the other hand, a laptop comes with a 16:9 horizontal display.

The aspect ratio can also vary depending on the monitor you are pairing it with. For instance, old monitors used a 4:3 aspect ratio. Today, most modern monitors typically use the 16:9 aspect ratio. The super wider monitors can have a wider aspect ratio as wide as 32:9.

Luckily, most operating systems can accommodate other aspect ratios and adjust depending on the connected monitor. 

What is the Importance of Aspect Ratio?

Aspect ratios are essential for the very reason that many standards exist for varied applications. A software developer dealing in smartphone development won't use the same aspect ratio as a developer creating PCs. A phone will likely have a 9:19 vertical aspect ratio, while a PC will likely have a 16:9 horizontal aspect ratio.

The monitor connected to a PC dictates what aspect ratio the PC will use. If you connect your PC to a monitor with an aspect ratio of 4:3, common in older monitors, then your PC will automatically shift to a 4:3 aspect ratio. Mainstream monitors have a 16:9 aspect ratio, while other ultra-wide monitors have aspect ratios of 32:9. Fortunately, the PC's Operating System can automatically adjust to fit several aspect ratios to accommodate the connected monitor.   

Camera sensors are, however, limited to a specific aspect ratio. To change the aspect ratio of an image, you'll need to crop it to fit your desired aspect ratio. You can take your photo and alter it using Adobe Photoshop to match the aspect ratio you want (see monitors for photo editing).

Then, what is the ? 4K is a term used in cinematography and digital TVs technologies to describe a sharp and quality display having a horizontal pixel count of around 4000 pixels. 4K monitors have 3840 x 2160 display resolution.

How to Measure Aspect Ratio

Today, you can find a phone app or an aspect ratio calculator online. However, it'll be best to do the calculations yourself for the first time to understand the process. Any aspect ratio calculator will use the following formula:

(Original height /width) x new width - the new height

If you are using the aspect ratio calculator to measure the aspect ratio, follow the steps given below.

  1. Determine the original width and height.
  2. Divide the original width with the original height. 
  3. Proceed to multiply the results by the new width.
  4. The figure you get represents your new height for the edited image.


An image measuring 1600 pixels by 1200 pixels means its width is 1600 pixels, and the height is 1200 pixels. This figure represents the original width and the original height. Given that you need to reduce the width to 400 pixels, 400 will be your new width. To determine the aspect ratio, you'll use the aspect ratio formula given below.

  1. Divide 1600 with 1200 to get 0.75. 
  2. Multiply 0.75 by 400 to get 300. 
  3. In this case, 300 represents the new height. 
  4. Therefore, the aspect ratio is 400/300 or 1600/1200, which gives a 4:3 aspect ratio. 

Calculating the aspect ratio is a matter of what you're dealing with. The calculation will depend on whether the matter is a video, image, or design assignment. 

The aspect ratio is a measure of width and height. Besides, it's used in varied applications. Therefore, the aspect ratio is reduced to the smallest unit possible to fit the multiple applications.

What is an Aspect Ratio Calculator?

An aspect ratio calculator is a program that gives a precise calculation of the aspect ratio of an image, design project, or video. 

Determining the aspect ratio of an element involves many calculations. The aspect ratio calculator comes in handy to do these calculations faster. To find the precise formats for your design project or video, you only need to key in one dimension. Depending on the aspect ratio, the calculator will calculate and give accurate measurements of the other dimension. 

The aspect ratio calculator gives accurate aspect ratios and dimensions of images and video projects.  

What Aspect Ratio Should I Use?

The use of aspect ratios depends on several factors. Each aspect ratio has its application that can't overlap.

  • You should use a 1:1 aspect ratio when taking photos to post on your socials. For example, photos you post on Facebook, Instagram, and Twitter. Therefore, your Instagram aspect ratio should be 1:1.
  • Use a 3:2 aspect ratio when shooting still images. And, of course, you'll find this aspect ratio in camera and phone sensors. 
  • Use a 4:3 aspect ratio when doing TV broadcasting.
  • You should consider a 16:9 when watching movies and dealing with computer displays. It is a standard aspect ratio that is widely used. This aspect ratio is also used when gaming. However, when playing games on bigger monitors, you should use the 21:9 aspect ratios. This is the case when playing games on 4K monitors. 
  • Use the 2.35:1: CinemaScope aspect ratio when filming cinemas.

What Is the Best Aspect Ratio?

No specific aspect ratio is better than the others in the market. If you are looking for the best aspect ratio for taking photos, your choice will depend on what you want to capture, how you want to display it, and the message you want to communicate.

Certain aspect ratios are best for creating memories, and you have many aspect ratios meant for image and video display. For instance, the 4:3 or 1.33:1 aspect ratio was the widely used aspect ratio for old televisions before the invention of the widescreen. The aspect ratio would result in a square image. Today, it is used to show events that happened in the past and to create nostalgic memories.

On the other hand, you have the 16:9 aspect ratio that is mainly used in TVs and monitors. The aspect ratio is common for the internet and TVs. Some photographers will use the video's aspect ratio while cropping their photos, which helps to create a cinematic look for the images.

The 1.85:1 ratio is the most common widescreen aspect ratio. It is wider than the 16:9 aspect ratio and gives you some details on the sides. It is not ideal for most modern monitors and televisions, but you can deal with the issue by adding black bars on the bottom and top of the screen.

Additionally, the 2.39:1 is the aspect ratio used to create a more immersive watching experience. It is also known as the anamorphic format, and filmmakers and photographers can use the specialist anamorphic lenses on native cameras to capture the footage without overlaying the black bars or cropping the image. You can also use post-production software to return the image to normal, which results in a panoramic aspect ratio and a wider field of view. The 2.76:1 aspect ratio is not common, but it is ideal for ultrawide monitors.

Most mobile devices and digital cameras will allow you to change the aspect ratio before taking a photo.

Which aspect ratios are used in photography?

The 1:1 aspect ratio is ideal for medium film formats, resulting in a square image. The format wasn't common in photography until the coming of Instagram that only accepted the square format. Although Instagram now allows you to upload images in multiple formats, it gave way to the era of square photos where the image's width and height were equal. It is also the best format for uploading your profile pictures on Facebook, Twitter, etc., since they display the profile in circles.

If you want to showcase your artwork and photos, the 3:2 aspect ratio is an excellent option. The image format is a match with various print sizes. Standard print sizes with a 3:2 aspect ratio include 24x36", 4x6", and 16x24".

The 4:3 aspect ratio is an excellent option to showcase your images on a digital photo frame. It is the same aspect ratio you find in computer monitors and TVs. It is also the most common image output for most smartphones. You can also select other aspect ratios to shoot videos and photos on your smartphone. However, it will result in some cropping and a loss of quality and resolution.

Choosing the Right Aspect Ratio

Getting the correct aspect ratio is a vital aspect of determining the mood of your artwork. The choice of aspect ratio will help you focus your audience's attention on particular details of the image. It can also help you create a fantastic environment that will offer your audience an immersive experience.

It'll be best to choose your preferred aspect ratio before shooting your video. Using software to change the aspect ratio post the shoot can mess up your work by reducing the resolution and quality. Additionally, you can make various compositions using different aspect ratios before settling on one. Doing so will help you decide on the best aspect ratio during production.

Ensure that your choice of aspect ratio is ideal for telling your story.

What is a Vertical Video?

The vertical video refers to the newest aspect ratio in the filmmaking industry. Most filmmakers may tell you that taking vertical videos is something you shouldn't do. However, the content you record is for internet consumption which doesn't care about the classic proportions.

Since the aspect ratio is new, you can try it out and be part of the leading innovation.

Which Aspect Ratio Should You Choose Between 16:9 vs. 4:3? 

Before recording a video or taking a photo, it'll be best to choose an ideal aspect ratio. The 16:9 and 4:3 are two of the most common ratios you'll come across. Probably you are wondering which of the two aspect ratios is the best for you. Depending on the nature of your project, each of the aspect ratios will come with its pros and cons.

For instance, the 16:9 aspect ratio is the best for recording videos because it is 78% wider than it is tall. The aspect ratio also referred to as widescreen, is more effortless to fit on your screen. With the aspect ratio, you'll record more information vertically, and it will offer a better display on most modern computer screens and TVs.

On the other hand, the 4:3 aspect ratio is a perfect fit for photography work since it is 33% wider than it is tall. It is the best choice of aspect ratio for print purposes.


The aspect ratio is a vital factor to consider when recording a video or taking a photo. If you choose the wrong aspect ratio for the job, you'll end up cropping the image, which affects its quality and resolution. For instance, displaying a 4:3 aspect ratio on a 16:9 display will create borders on either side of the image.
