Hi,
I just need a list with all the aspect ratios that are used in mobile devices. For ex. 3:4, 9:16, etc…
If someone has a list with real existing aspect rations in todays mobile devices would really help me. I don’t need the model of the device. Just the ratio.
Thank you,
Gerald.
Some new android flagship smartphones are 18:9 and 18.5:9. Most commonly available android devices are 16:9 aspect ratio.
For iOS, 9:16, 3:4 and 2:3 for older devices will cover all aspect ratios.
This is really helpful. Thanks 
A useful table, but using the term “rotated” isn’t the best option. It took some working out it that “rotated” is portrait (I originally said landscape, but meant portrait).
Have no idea why they use “rotated” instead of landscape. It is understandable by the ratio 16:9(width:height) which is landscape and 9:16 which is portrait. If the width is greater it means that it’s orientation is horizontal or landscape and vice versa. 
Maybe I am wrong. Rotated might be both of orientations, landscape and portrait.
Just keep in mind that the information in the stats page is almost a year out of date. It stopped updating Dec 31st, 2016.
Some additional new aspect ratios for those who may search in the future.
9:18,
9:18.5.
