What is a 3:2 aspect ratio?

Common Aspect Ratios

The 3:2 aspect ratio is among the most popular photography print sizes and productivity-focus computer displays. It was first used in 35 mm film[1] to store a landscape 3:2 or portrait 2:3 still photography.

It's also the trending aspect ratio for modern laptop displays and monitors optimized for productivity since it provides a taller viewing area than the standard 16:9 display, which is excellent for working on documents and spreadsheets.

For example, Microsoft Surface Pro[2], the new 2-in-1 Dell XPS 13[3], and other recent Windows laptops use a 3:2 ratio display for better productivity and provide better tablet experiences in both landscape and portrait mode.

The aspect ratio has a standard format of 3:2 or W:H, where W is the width and H is the height of an image, screen, or container. In digital space, the measurement unit is in pixels. You can pronounce it "three-by-two" or "three-to-two" aspect ratio.

FAQs

How do I calculate the 3:2 aspect ratio?

The 3:2 aspect ratio is a screen or image format that proportionally contains three units horizontally for every two vertically. It can be calculated by dividing the width by height and getting a value of 1.5.

For example, the ratio between the width and height of the HD+ (1200 x 800), Full HD+ (1920 x 1280), and 4K+ UHD+ (3840 × 2560) resolutions are equal to 1.5.
