Technical notes › Customise Wireshark’s font, theme, and columns
I don’t just find Wireshark’s default interface ugly, I find it hard to read. When the
So, I like to make a couple of changes:
- Because we’re dealing with wide tables of text, I recommend changing the font to one that takes up less horizontal space. A thinner font such as Iosevka lets Wireshark pack more data in, so you don’t have to scroll as much.
- The Time column can be made slimmer by setting the menu option View → Time Display Format → Millisecond. Timestamps with three decimal places are still accurate enough for almost anything.
- By right-clicking the column headings of the table, you can right-align or centre-align their data. I find that changing this setting for certain columns makes the table more readable by spacing the data out, and lets you more easily tell which piece of data is which. (And timestamps should be right-aligned anyway, because they’re numeric.)
Finally, in the Layout section of Wireshark’s settings, you can put the two panes of data at the bottom — the packet tree and the hexadecimal data — side-by-side, so they take up less space.
