Screenshot sizes for publishing on Google Play not working
You need to resize your screenshot. Constraints:
- Min length for any side: 320px.
- Max length for any side: 3840px.
- Max aspect ratio: 2:1.
In your case, the aspect ratio is not correct. If you want to maintain the width of 800px, then the maximum height can only be 1600px (or a minimum of 400px).
Just as mentioned in the 1st answer your resolution should be in a ratio of "2:1" So I was using Samsung galaxy S9 screenshots that had a resolution of 1080x2220 So to make it 2:1 I just went to an online image resizer like thisand resized the image to 1080x2160 where it doesn't exceed the 3840px max limit either, and the image upload was a success.
Hope the answer helps :)
it means to change your height and width of your image. aspect ratio 2:1 means two times height more than width. if your width is 800 then your height should be 1600. for example in Photoshop you can do it with change the size of image in image menu/image size.
