Common Image Aspect Ratios
2:3 Aspect Ratio
2:3≈0.666, which is close to the golden ratio. The full-frame size ratio for camera photography is 2:3, and other sizes are created through cropping, so it looks more comfortable in applications. This ratio is mostly used in landscape images, such as product lists and banner images.
3:4 Aspect Ratio
The 3:4 design is also common in interfaces. Compared to 2:3, the image is more compact, and it is mostly used in apps where images occupy a larger proportion, as well as in product lists and banners.
1:1 Aspect Ratio
1:1 is also a square composition. This composition has a larger image proportion, so it is mostly used in apps for product displays, avatars, close-up displays, and other scenarios, and it is more common in e-commerce design.
16:9 Aspect Ratio
16:9 is mainly a common composition in movies. This composition gives a visually open feeling and is mostly used in video apps.
Golden Ratio 16:10
16:10=1.6 is the closest to the golden ratio 1:0.618=1.618, so some designs now also start to use 16:10. For example, 1920 x 1200 pixels.
