why is my wallpaper on IOS 9 zooming in by its self and i can't size it

Hi MLGPRO2016,

Welcome to the Apple Support Communities! I'm sorry to hear you are having these issues with your iPhone. The zooming you are seeing may be due to the parallax effect, a feature which provides movement and depth to backgrounds and interfaces in iOS. To see if this is the case, you may want to try turning on the Reduce Motion option as outlined in the following article:
