I don't really know what's the best sizes for creating phone, desktop, and tablet wallpapers. I wanted to create some for my new ko-fi page but I don't really know what sizes I should use. When searching the web for an easy answer, I got multiple instead... So that really didn't help me much.
I understand that multiple devices have various screen sizes, but I feel I need to get whatever is the most accurate sizes so I won't have to much trouble trying to get the proportions right. Plus, I don't own a lot of devices like Apple brand products for example. So I won't be able to properly test them before submitting them to my Ko-fi. Any advice would be helpful. Thanks in advance.
