Wall papers cannot resize scale in ios 11.0.3

Hey guys... why does apple STILL have this problem?? When choosing a foto from my libriary (pic you shot) you cant rescale it to fit the sides of the screen. It is ALWAYS TOO BIG?? How can you solve this big PITA?? Reduce motion option off. Google has no answers. Refers to old ios versions. They keep saying there's a perspective option you can turn off but it doesnt exist in ios 11.0.3. Anyone know how to set wall paper to fit exactly as they appear in library instead of zooming another 25% off the screen under wallpaper option?? Thanks.
