Yes, I didn't realize you could "pick" a size. I was under the impression that the new banner layout will be the maximum size, and depending on how you design it your logo may or may not be visible on each device group.Maximum. I don't see why someone would use the minimum banner, if seen on other devices, it will look very unprofessional.
You don't get to choose, but some people are making their banners only in the 'safe area'. I think what is going to happen, is they will stretch the banner image out to the whole 2120 X 350 px. So those people who only made it in the safe area are going to have one messed up looking banner haha.Yes, I didn't realize you could "pick" a size.
