[size=NUMBER]text[/size]

The [size] tag is used to stylise text through the use of differing font sizes. Currently, there are four sizes that are supported by the osu! website: 50, 85, 100, and 150. The sizes are internally referred to as "tiny," "small," "normal," and "large" respectively.

The NUMBER argument does not accept quotation marks, and only accepts one of the four supported sizes. If a number, that is not one of the supported four, is inputted, the text will revert to the default size.
