Enlarging the Icons

select the Applications list, and then in the list of applications double-click
Terminal within the UTILITIES folder), and type the following two lines, the first
of which refers to the number of icon rows and the second of which refers to
the number of icon columns:
DEFAULTS WRITE COM.APPLE.DOCK SPRINGBOARD-ROWS -INT 4
DEFAULTS WRITE COM.APPLE.DOCK SPRINGBOARD-COLUMNS -INT 4;KILLALL DOCK
Then activate Launchpad to see the changes.

Shrinking the Icons

DEFAULTS WRITE COM.APPLE.DOCK SPRINGBOARD-ROWS -INT 10
DEFAULTS WRITE COM.APPLE.DOCK SPRINGBOARD-COLUMNS -INT 10;KILLALL DOCK
Experiment with the settings until you find something you like, but be aware
that each time you reduce the number of rows and columns, you're also
