Windows 10

Microsoft didn’t publish any guidelines, so we had to read it in tea leaves follow the icon examples in the beta versions of the Windows OS and icon font introduced by Microsoft.

We have even created our own style guide for Windows 10 icons. Here’s what we found out:

Application Icons and Control Panel Items

The icons should be in .ico file format. win_app
The full set should includes following icon sizes:

  • 16×16
  • 32×32
  • 48×48
  • 256×256

Toolbar Icons

Note that toolbar icons should always be flat. win_toolbar

  • Windows 10: 32×32
  • Windows 8: 16×16, 24×24, 32×32

Dialogs and Wizards

Required Sizes: win_dialog

  • 32×32
  • 48×48

Android Lollipop, Marshmallow, Nougat

Android starting with version 5 Lollipop uses the Material design specifications for icons.
And the prize for the most detailed icon style guide goes to… Google! They have patiently described everything: from corner shapes to shadow sizes and opacity. Here are just a few of the main ideas.

Application Icons


Android expects product icons to be provided at 48dp, with edges at 1dp. When you create the icon, maintain the 48-unit measure, but scale it to 400% at 192x192dp (the edge becomes 4dp).


System icons

These icons symbolize a command, file, device, directory, or common action like trash, print, and save.


System icons are displayed at 24dp. When creating icons, it’s important to design at 100% scale for pixel-accuracy, while zooming in for precision.

Unix-like Operating Systems

It’s worth mentioning icon specifications from the work environments of Unix-like operating systems: GNOME and KDE. These apply to Linux, FreeBSD, and others.


GNOME uses a soft, three-dimensional look. This style is achieved by using antialiasing, shading and highlighting techniques. The supported image file formats are PNG, XPM and SVG.
Bold denotes the primary size for Linux icons.
Object and document icon 24×24, 48×48, 96×96
Application icon 24×24, 48×48
Toolbar icon 24×24, 48×48
Menu icon 16×16

KDE Icons

KDE is the default work environment on many Linux distributions. They have no official guidelines for icons, but here’s what we found on various KDE forums.
Desktop icon 16×16,22×22,32×32,48×48,64×64,128×128,256×256
Toolbar icon 16×16,22×22,32×32,48×48
Main toolbar icon 16×16,22×22,32×32,48×48
Panel icon 16×16,22×22,32×32,48×48,64×64,128×128,256×256
Dialog icon 16×16,22×22,32×32,48×48,64×64,128×128,256×256

Windows Phone

These are the sizes for required icons in the XAP package and for Windows Phone Store. winphone_app
Application icon 62×62
Application tile image 173×173
Device application icon for Windows Phone Store catalog (small) 99×99
Device application icon for Windows Phone Store catalog (large) 173×173
Desktop application icon for Windows Phone Store catalog 200×200

If you’re anything like us, all these dimensions are making you dizzy. Fortunately, we can use this list now, too.
