In the following article we will shed light on the features of every layout:

Grid layout

By choosing this layout, all of the items will have the same width and the same height as well. If the items are not the same size, they will be cropped. You can also define the number of columns for this layout.

This layout is the opposite of Masonry layout. In other words all of the items with Justify layout will have the same height but different width. You can set a height for the items in Justify layout. 
Justify layout consider the aspect ratio for each item, so that by changing the height of items, you may experience a different look for this layout.
Here are some example of Justify layout. All of the examples have similar items but in different heights:

Justify 2
justify 3

This layout just lists all of the items vertically with the same width. The width and height of the items will be automatically defined in List layout and users have no control of them.
