This template is used to display a small flag icon next to a wikilinked country name. It is related to the {{flag icon}}, {{flag country}} and {{flagu}} templates, but offers more options in terms of the text string displayed.

See Wikipedia:WikiProject Flag Template for the main documentation/discussion page for the flag templates system.

Usage

{{flag|country identifier|optional variant|name=alternative text string|size=maximum width and/or height of the flag image}}

country identifier is the common name of the country (e.g. "United States"), a common alias (e.g. "US"), or a standard country code such as those listed at ISO 3166-1 alpha-3
variant is an optional second parameter that can be used to display a flag variation, such as a historical flag. The list of variants for each country is documented on the appropriate template page, such as Template:Country data Germany
alternative text string, this optional value, specified by the name parameter, is used to display alternative text
size, this optional value is specified by the size parameter, and is used to specify the maximum width and/or height of the flag image. This parameter is specified using standard image syntax.

See the prefix index for the templates latently called by this one.

Examples

Wiki markup	Displays	Notes
`{{flag\|United States}}`	United States	Note that all instances link to United States.
`{{flag\|US}}`	US
`{{flag\|USA}}`	USA

`{{flag\|Germany\|empire}}`	Germany	Flag variations can be used with either country names or country codes.
`{{flag\|DEU\|empire}}`	DEU
`{{flag\|CAN\|name=Canadian}}`	Canadian	The name parameter can be used to change the display string but keep the link to the correct article.
`{{flag\|Canada\|1957\|name=Canadian}}`	Canadian	The name parameter can also be used when flag variants are specified.
`{{flag\|Texas}}`	Texas	Flags are also available for several sub-national and multi-national entities such as US states, Canadian provinces, and the European Union. A complete list can be found at Category:Country data templates.
`{{flag\|British Columbia\|name=BC}}`	BC
`{{flag\|EU}}`	EU
`{{flag\|Switzerland\|size=14px}}`	Switzerland	The size parameter can be used to control the image dimensions. 23×15px is the default size for most countries (some entities have a different default size).
`{{flag\|Switzerland\|size=28px}}`	Switzerland
`{{flag\|Nepal}}`	Nepal	Some flags are non-quadrilateral.

Alternatives to avoid Wikipedia's Post-expand include size limit

Pages with many flags may come close to or exceed Wikipedia's Post-expand include size limit. In these cases consider using modules or module-wrapper templates instead:

For many countries, using the country code as the template name will act as a wrapper for Module:Flagg: For example, {{flag|''USA''}} can be replaced with {{USA}}, which has an include size that is about 15% smaller.
{{#invoke:flag||}} is a wrapper for Module:Flagg that can further reduce sizes when invoked directly. For basic use, {{flag|country}} can be replaced with {{#invoke:flag||country}} which has an include size that is about half.
