Tab Bar Design Example
The icons and their labels on the Tab Bar need to be spaced by eye rather than by a mathematical equation. This is to ensure that the white space between each icon and label looks visually similar.

Unfortunately, Font Awesome icons vary in size. Therefore each icon requires consideration of its height and width to ensure, when put together, all icons look similar.

Correct
The white space between the icons and their labels is visually similar.

Incorrect
This example demonstrates that evenly distributing the icons and their labels results in the Post button being un-centred.

Incorrect
The Post button is centered but the other labels and icons are randomly distributed resulting in uneven areas of white space.
