The aspect ratio of a Mac screen is an important consideration when setting up your computer. It affects how the image appears on the display, and can be the difference between a pleasing viewing experience and an unsatisfactory one.

Understanding Mac Aspect Ratio
The aspect ratio of a Mac screen is measured in terms of width to height or “length:width”. The most common ratio for Macs is 16:10, which is considered to be the ideal size for most users. This corresponds to a resolution of 2560 x 1600 pixels, giving you 227 pixels per inch (ppi) on your display.

Changing Your Mac Aspect Ratio
If you want to change your aspect ratio, you need to open System Preferences on your Mac. You should then click Displays, where you’ll find the option “Default for Display” selected by default. If you change this option to “Scaled”, it will equate to an approximate 15.4:10 aspect ratio, making the screen appear taller and narrower than other Macs due to the area uder the notch / menu bar being 16:10 instead.

In addition, some TVs or projectors may have a setting called Underscan that can be used to adjust picture size. To access this setting, choose Apple Menu ? > System Settings (or System Preferences), and then click Displays.

Aspect ratios are an important consideration when using a Mac computer as they affect how images are displayed on your screen. By changing your aspect ratio in System Preferences, you can customize the image size for an optimal viewing experience that suits your needs and preferences.

Understanding the Mac Aspect Ratio

The aspect ratio of a Mac is the ratio of the width of the display to its height. For most Macs, this is 16:10, meaning that for evey 10 units of height, there are 16 units of width. This gives a widescreen display with a more rectangular shape than traditional monitors, which usually have an aspect ratio of 4:3 (or 1.33:1). However, Apple recently released the new M1-powered Macs with an aspect ratio of 15.4:10 – giving it a slightly taller and narrower shape compared to other Macs. This is because the area under the menu bar (which includes the notch) is actually still 16:10, while the rest of the screen has been slightly narrowed down to fit within this same area.

Adjusting a Mac Screen to Fit a TV

To adjust the size of your Mac screen to fit your TV, you can use the Underscan setting. First, open System Settings (or System Preferences) from the Apple menu ?. Then select Displays. In Display Settings for the TV or projector, look for a setting named Underscan. If it is available, you can use this setting to adjust the picture size so that it fits your TV perfectly.

This results in a screen resolution of 2560 x 1600, with a pixel density of 227 pixels per inch (ppi). The 13.3″ Retina Display offers over 4 million total pixels for stunning image quality and sharpness.

Is the 16:9 Ratio the Same as 1920×1080?

Yes, 16:9 ratio is the same as 1920×1080. This ratio is also known as “Full HD” or “1080p,” and it is the standard for high definition video. It has an aspect ratio of 16 units wide by 9 units high, whih can also be expressed as a resolution of 1920×1080 pixels. This aspect ratio is used in digital cinema projection systems, and it’s the most popular resolution used in modern monitors and televisions.

The Benefits of Macs Using 16 By 10

Macs use a 16:10 aspect ratio screen because it provides a more balanced workspace. This aspect ratio offers more vertical space than traditional 16:9 screens, allowing for more ergonomic viewing of documents and other work. Additionally, 16:10 is an ideal ratio for multitasking, as it allos users to view multiple windows at the same time with minimal overlap. Furthermore, the wider display makes for an enhanced visual experience when viewing videos or playing games. Finally, Apple has chosen this aspect ratio for its Macs because it offers a unique aesthetic that fits well with their minimalist design philosophy.

Understanding Aspect Ratio in Laptops

The aspect ratio of a laptop is the ratio of the width to the height of its display. The most common aspect ratios for laptops are 16:9 and 16:10, which represent the width-to-height ratio of widescreen displays. A laptop with a 16:9 aspect ratio can display HD video and other content in its native resolution without any scaling or letterboxing. On the other hand, a laptop with a 16:10 aspect ratio will require scaling in order to display content in its native resolution. Aspect ratios of 4:3 and 5:4 are also seen on some older models, although they have becoe less common over time as widescreen displays have become more popular.

Aspect Ratio of 1024×768

The aspect ratio of 1024×768 is 1.33:1. This resolution is commonly used in computer display systems and involves dividing the horizontal display resolution (1024) by the vertical display resolution (768). The resulting number (1.33) is referred to as the aspect ratio and describes the proportional relationship between the width and height of a prticular video or image.


In conclusion, the aspect ratio of a Mac screen is usually 15.4:10, although the area under the notch/menu bar remains at the traditional 16:10 aspect ratio. Users can adjust their display settings and even select a resolution with an aspect ratio of 16:10 if desired. Furthermore, cetain models like the 13.3″ Retina Display possess an additional feature with a higher resolution of 2560 x 1600 and 227 pixels per inch (ppi). This provides users with an even more enhanced viewing experience.
