MIME Type Icons

MIME type icons are used to depict documents and files. They come in four sizes: 16px, 22px, 32px, and 64px. MIME type icons use the monochrome style for 16px and 22px sizes, and the colorful style for 32px and 64px sizes.

Purpose

MIME type icons allow a user to quickly recognize the types of their files without needing to look at a file’s extension or contents. They primarily appear in file listings in large amounts, and their design reflects a sense of unity among files in a user’s system.

Design

Margins

64px MIME type icons have a top and bottom margin of 3 pixels, and 32px MIME type icons have a top and bottom margin of 2 pixels.

64px icons should have a top and bottom margin of 3 pixels.
32px icons should have a top and bottom margin of 2 pixels.

Anatomy

Colorful MIME type icons consist of two elements—the monochromatic counterpart of the colorful MIME type icon overlaid on a background relating to the icon’s type.

  1. Monochromatic Foreground
  2. Base
The foreground of a MIME type icon indicates the specific type of file it is.
The background of a MIME type icon indicates the general type of file it is.

Base

The base of a MIME type icon serves to give files of a general type a shared and recognisable silhouette

Archives

Archives, packages, compressed files, and disk images use a square with a zipper going halfway down.

For archive icons without a foreground, the zipper goes through the center.
For archive icons with a foreground, the zipper is offset to give the foreground some space.

Images

Images use a horizontal rectangle with the top right corner folded and casting a shadow.

The base for image type icons.

Videos

Videos use a horizontal rectangle styled to look like a filmstrip.

The base for video type icons.

Audio

Audio files use a CD sleeve with a partially visible CD sticking out.

The base for audio type icons.

Books

Book files use a vertical rectangle with a book spine.

The base for book type icons.

Other

Documents and other icons use a rectangle with a fold in the top right corner casting a shadow.

The base for document and other type icons.

Foreground

The foreground of a MIME type icon serves to inform the user about the specific type of file an icon represents. The foreground should be the monochromatic icon of the MIME type.

The foreground decoration of a MIME type icon does not cast a shadow.
Don't have the foreground decoration of a MIME type icon cast a shadow.

Color

The color of a MIME type icon helps inform the user what kind of icon it is. Icons for MIME types associated with a brand identity should use the colors of that brand identity.

The usage of Android brand colors helps users identify the icon as that of an Android package.
Don't use radically different brand colors---users will not recognise the icon as one of a filetype from that brand.
