I think that the standard icon size on my iPhone is too big. However, people with poor vision will benefit from larger icons instead. If you iOS device is jailbroken, the icon size can be customized.
It is unbelievable how apple restricts users on the customization front. Many users would strongly appreciate at least some freedom regarding personalization and customization. By their nature, jailbroken devices have many of these limitations removed.
1.Open up the Cydia app from your springboard.
2.In the Cydia application, tap on Search at the bottom right corner.
3.Now search for Bigify. Two options should come up: one in blue and one in black. Tap the black one as the blue links in Cydia are for paid tweaks.
4.One on the Bigify screen, tap Install.
5.On the next screen, tap Confirm.
6.Once the package finished installing, tap on Restart SpringBoard.
7.After your SpringBoard restarted, open up the Settings application.
8.In the Settings app, scroll down until you find the newly installed Bigify application. Tap on it.
