This Original Size icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
The icon is a rounded horizontal rectangle. On this card is inscribed "1:1", as tall as two thirds of the rectangle's height, representing a zoom ratio indicative of the icon's original size. The icon represents setting the zoom level to the original level.
