While working with a packet capture, most users are comfortable with the default values used in the interface. However, you can adjust font styles and size to personalize the look and feel of the interface. In addition, you can also modify the colors Wireshark uses for the various packet identifiers and display filters.

Once you are on the interface, you will see the columns and column headers that are along the top of the interface. While you are working in the interface, you might not ever manipulate the columns. However, you can add, delete, align, and customize the column at any time.

Wireshark makes it easy to add and modify columns, as we'll see in the next section.
