Reduce oversized icon to match others?
One icon is much larger than all others. How do I reduce the size to match all?
Question marked as
Perhaps the on-screen icon to which you refer is actually a Widget - these being larger than App and folder icons.
App, folder and Widgets are arranged in grid layout. While Apps and App folders occupy and placed centrally within a grid-square, Widgets can occupy multiple grid-squares. While some Widgets can be chosen to be larger or smaller, they cannot be freely re-sized.

Your iPhone's Display Zoom setting can also change the size of your on-screen App and folder icons:
Settings > Display & Brightness > [Display] Display Zoom - select Default for smaller icons - or Larger Text for larger icons
