Miui Vs other launchers

I've been using MIUI for a while now - main reason being the icons are spaced out with correct size. With 5 rows and 4 columns their sizes look like iphone. But when i use the same 5x4 with other lauchers the icons and the labels are too small for me to read..Not sure why?

I'd love to use APEX or nova if i can get the same layout as miui - they're more flexible for icon change and app drawer etc..

Any ideas or tips?
