LG V10 5 icons in a row

Hello, I am from HK and new from this forum. I would like to ask a question about my LG V10.

The icons on the desktop is 5 in a row. I have seen from others’ phones which have bigger icon and they are 4 in a row. I cannot find a way to change the setting in the display. Is there anyway to change the icon size and from 5 in a row to 4 in a row?

Thanks for your help.
