What are the sizes of the system tray icons?

Question

I want to change the notification icon of my application, but I don’t know what size so that it displays correctly. Currently, it is automatically resizing and breaking my pixels! Please, help!

Answer 1

It is 16x16. If you create a .ico file that supports sizes 16, 32, 48 and 256, you will be closed.

Answer 2

In fact, the icon size will vary depending on the DPI system.

WPF SystemParameters.SmallIconWidth SystemParameters.SmallIconHeight. (WinForms SystemInformation.SmallIconSize - GetSystemMetrics SM_CXSMICON/SM_CYSMICON.)

Microsoft 16x16 32x32 .

Answer 3

XP 16 x 16

Answer 4

Outlook 16 * 16 .

Answer 5

I believe that it was always 16x16, but at some point between 98 and XP (maybe it was CE versus NT?) They learned to support full color and alpha transparency. If possible, try including the 256 color pallet version in ICO for safe mode, if not older versions of Windows.

Answer 6

In ubuntu (unity) it seems 24x24 px.

Answer 7

In the system tray, Windows 7 has 16 * 16 pixel icons.
