We've already given you some suggestions on how to fix issues with wallpaper resizing in iOS 7 and Wallpaper Fix is another technique, albeit a simpler one. Just choose the image you'd like to use as a wallpaper on your iPhone or iPad inside of Wallpaper Fix, resize it, and export it to your Camera Roll. That's all there is to it.

While disabling Parallax can help a little when it comes to wallpapers being magnified in iOS 7, it doesn't completely solve the problem. That's where apps like Wallpaper Fix are gaining some traction since they fix an issue that Apple has yet to address. Wallpaper Fix lets you freely zoom in and out and even rotate an image in order to produce the desired results.
