Change Launchpad Icon size in Mac OS X El Capitan: Do you want to change the size of your icons in the Mac OS X Launch Pad so they aren’t quite as big? All you have to do is follow these simple steps.
You can start by checking the number of lines / rows you have in your OS X Launch Pad.
Just count the rows and the columns. I that case we have: 5 rows and 7 columns.
Step 1: Open up the terminal. The first value that you will see is how many rows you want to have in the Launch Pad. The second value is how many icons you want to have in one row.
Step 2: Simply copy the following command lines:
defaults write com.apple.dock springboard-rows -int 4
defaults write com.apple.dock springboard-columns -int 10
into the terminal and press enter.
You will notice that the Launch Pad icon size will instantly change. Now you have 4 rows and 10 columns as the commands dropped in the terminal.
An example with 8 columns and 5 rows.
One extra example with 10 columns and 7 rows.
The great thing about this method is that you can enter your own values so you can decide how many rows you want to have in Launch Pad as well as the number of icons you want per row.
It is highly recommended that you take the time to play around with this until you finally get the configuration you want.
This is a very simple way to change the Launchpad icon size without any complicated tricks or hacks.
