How to Make Icons Larger or Smaller on a Mac

The icons on the Mac desktop and in any Finder window can be resized according to your preferences. Large icons are easy for children or people with poor vision to see and use, while small icons keep your desktop from looking cluttered and allow you to access more apps without scrolling in Finder windows. On a Mac running OS X Yosemite, change the sizes of the icons using a slider in "Show View Options."
