How can I increase the size of these System Tray Icons? :
Update: In Debian 11, KDE Plasma 5.20.5, there is now an option to scale system-tray icons to the panel's height. Here's is a short video showing that. Thanks goes to KDE!

Open ~/.config/plasma-org.kde.plasma.desktop-appletsrc with a text editor.
Find every line starting with extraItems=
Add another line iconSize=3 below each of those.
Save the edited file and exit.
After a reboot the icons should have a much higher limit of size when adjusting the height of the panel.
- 1Oooh, that's fantastic. It should do that by default. At the very least, you should be able to right-click on the system-tray and configure this setting instead of having to modify some text files.

- It doesn't work for me, Plasma Systemtray version 1.0, shell version 5.20.2xryl669– xryl6692020-11-13 12:15:00 +00:00Commented Nov 13, 2020 at 12:15

- Thanks again for showing me this solution; it got me through Kubuntu 20.04. Today I noticed that KDE Plasma (5.20.5) now provides this as an option in the GUI. It comes default in Debian 11.Lonnie Best– Lonnie Best2021-11-16 18:52:23 +00:00Commented Nov 16, 2021 at 18:52
- You do not have to reboot, it's possible just to reload Plasma and surprisingly it works: askubuntu.com/questions/481329/…o3bvv– o3bvv2022-01-07 10:03:02 +00:00Commented Jan 7, 2022 at 10:03
Debian 11, KDE Plasma
In order to increase the size of systray icons, you need to edit the file
/usr/share/plasma/plasmoids/org.kde.plasma.private.systemtray/contents/ui/main.qml Find the string
readonly property int smallIconSize: units.iconSzie.smallMediumReplace
smallMedium(22 log. px) withmedium(32 log. px),large, or use integer value (in physical pixels!)Save, log out, log in, or restart Plasma with
killall plasmashell ; kstart plasmashell
This file will get overwritten every time there's a Plasma update. To edit settings for a specific user only and avoid problem with plasma update, copy the entire plasmoid (systemtray):
cp -r /usr/share/plasma/plasmoids/org.kde.plasma.private.systemtray ~/.local/share/plasma/plasmoids/ and then edit main.qml and restart plasmashell.
FYI, this has changed as of Plasma version 5.21.4 (perhaps slightly earlier). The iconSize setting now does nothing.
To get this functionality, instead, at the same place where you would have inserted iconSize (per the other answers), put: scaleIconsToFit=true
Then simply killall plasmashell; plasmashell & as described and it will work perfectly.
- 1what works in newer Plasma is the new setting under "Configure System Tray" that lets icons resize with the pnelcipricus– cipricus2021-05-03 22:00:55 +00:00Commented May 3, 2021 at 22:00
- @cipricus I think I recall that being there too, but IIRC it was for fixed sizes and for me all of them were too small or too big.mikev– mikev2021-05-09 04:22:24 +00:00Commented May 9, 2021 at 4:22
- the version changes involved came (as many others) with 5.19.x. Now I'm back to 5.18 (kubuntu 20 LTS, so this answer works for me), but it's always good to have a solution for the future :)cipricus– cipricus2021-05-09 16:14:40 +00:00Commented May 9, 2021 at 16:14
- 1@cipricus ok. This works in the newer plasma too, is what I'm saying. (5.21.4, Kubuntu 21.04).mikev– mikev2021-05-10 17:56:18 +00:00Commented May 10, 2021 at 17:56
- 1This makes the icons gigantic when using a wider vertical panel. It would be nice to have an option to simply set the size in pixels or similar.tomasz86– tomasz862021-07-02 14:10:07 +00:00Commented Jul 2, 2021 at 14:10
The setting to change icon sizes, located in Settings > Appearance > Icons > Advanced, seems to have been unusable for years. I think this has been the case since some version of KDE 4. Possibly it is related to whether the icon theme is in a resolution-independent format (svg).
A hidden iconSize setting was added around plasma-workspace 5.9. Prior to the addition of this setting, qml files had to be edited.
To change the setting system-wide, edit the file:
/usr/share/plasma/plasmoids/org.kde.plasma.private.systemtray/contents/config/main.xml This file will be overwritten whenever plasma-workspace is reinstalled or updated.
To change the setting for a specific user, edit:
$HOME/.config/plasma-org.kde.plasma.desktop-appletsrc Look for the entry that corresponds to the system tray. It will look something like this:
[Containments][#] ... plugin=org.kde.plasma.private.systemtray ... Then scroll down until you see something that looks like this:
[Containments][#][General] extraItems=... knownItems=... showAllItems=true` Then add:
iconSize=# Where # is a number that refers to one of the following options:
0 ~ Small 1 ~ SmallMedium 2 ~ Medium 3 ~ Large 4 ~ Huge 5 ~ Enormous To see the changes log off and on. Or kill and restart plasmashell in a terminal window:
killall plasmashell ; sleep 1 ; kshell5 plasmashell 
- Sounds cool, but on my system (plasma-workspace 5.18.5)
iconSize=2is too big,0is too small,1is same as0. Display is 14' and 4K, I've adjusted few settings to make it look ok and icon size is last one to fix :)Dmitrii Vinokurov– Dmitrii Vinokurov2020-12-26 04:48:09 +00:00Commented Dec 26, 2020 at 4:48 - @DmitriyVinokurov Seems like a bug if 0 and 1 behave the same. I don't have any 4k displays, so may be related to that. I'm currently using 5.19.5.xiota– xiota2020-12-26 08:07:25 +00:00Commented Dec 26, 2020 at 8:07
iconSize=3line about 3 times (maybe its because I have 3 monitors and each one has a system tray on a tool bar), but each time I added a new line directly under the line that startedextraItem=. . .and then puticonSize=3onto that new line. After saving those changes to the file, and rebooting, the system tray icons where way bigger (like I like them).
