I am going to show you how to create a 2, 3 and 4 column layout but the actual module settings are the same for each version so let’s set that up, add a blog module and apply the following settings:

Layout: Grid
Posts Number: any multiple of the column layout you will be using
Include categories: Which ever ones you want to display
Show featured image: Yes
Read more button: Off
Show author: No
Show date: No
Show categories: No
Show comment count: No
Show pagination: That’s up to you
Featured image overlay: Off

Leave all the other settings alone.
