Wikipedia:Banner standardisation

A banner is a type of template that a WikiProject uses to indicate an article is within the scope of that project. In the past, our collection of WikiProject banners varied widely in nomenclature. Starting in mid-2008, a two-year push towards the most common form was commenced. With the final standardisation drive in mid-2010, a standard now exists in over 99 per cent of WikiProject banners. By 1 August 2014, only {{Maths rating}} was not at a standard name.

Standardisation assists editors who add project banners to new or untagged articles as well as makes things easier for bots and scripts that work with project banners, or editors trying to identify banner templates in the editing window. As such, it is encouraged that future banners use the standard Template:WikiProject Project form.
