Flag of Switzerland

The flag of Switzerland displays a white cross in the centre of a square red field. The white cross is known as the Swiss cross. Its arms are equilateral, and their ratio of length to width is 7:6. The size of the cross in relation to the field was set in 2017 as 5:8.[1]

The white cross has been used as the field sign (attached to the clothing of combatants and to the cantonal war flags in the form of strips of linen) of the Old Swiss Confederacy since its formation in the late 13th or early 14th century. Its symbolism was described by the Swiss Federal Council in 1889 as representing "at the same the Christian cross symbol and the field sign of the Old Confederacy".[2] As a national ensign, it was first used in 1800 during the Hundred Days by general Niklaus Franz von Bachmann, and as regimental flag of all cantonal troops from 1841. The federal coat of arms (eidgenössisches Wappen) was defined in 1815 for the Restored Confederacy as the white-on-red Swiss cross in a heraldic shield. The current design was used together with a cross composed of five squares until 1889, when its dimensions were officially set.[3]

The civil and state ensign of Switzerland, used by Swiss ships, boats and non-governmental bodies, is rectangular in shape and has the more common proportions of 3:2.[4] The Swiss flag is one of only two square sovereign-state flags, the other being the flag of Vatican City.[5] The emblem of the Red Cross is the Swiss flag with switched colours.


According to the 2017 flag law (SR 232.21),[6] "The Swiss flag shows a Swiss cross on a square background". Special provisions are made for the naval ensign and for civil aircraft identification.[7] The Swiss cross is defined as

Swiss Standard German consistently uses Fahne (cognate with vane) rather than the term Flagge used for national flags in Germany. The name of the flag of the Swiss Confederation is a nominal compound, Schweizerfahne.[8]

While the proportions of the cross have been fixed since 1889, the size of the cross relative to the flag (the width of the margin separating the cross couped from the edge of the flag) had not been officially fixed prior to 2017. The annex to SR 232.21 provides an image specifying that the margin is to be of the same width as the cross arms, so that the total height of the cross is fixed at 20:32 = 5:8 of the height of the flag (in other words, the width of the margin is 6:32 = 3:16). This ratio is also given as a "vexillological recommendation" in the flag regulation used by the Swiss Armed Forces.[9] Flags with a cross of larger relative widths than the prescribed 20:32 = 62.5% remain in wide use; common ratios include 20:26 ≈ 76.9% and 20:28 ≈ 71.4%.[10]

For the ensign, the ratio of the size of the cross to the height is likewise 5:8, so that the ratio of cross to flag width is 5:12.[11]

The shade of red used in the flag was not defined by law prior to 2017. The 2017 flag law specifies the colour of the flag as:

In 2004, the Federal Chancellery published a corporate design guide for the federal administration, in force since 1 January 2007. The colour specifications given there are compatible with those later put in the annex to the flag law.[12] The matching of heraldic tincture to modern color specifications for print or screen display is very uncertain, and to some extent left to the discretion of the publisher. A 2004 source specifies "Pantone Red 032 C", or RGB #F00000, for heraldic red.[13] Recommendations for using "web safe" colours for electronic displays have partly been obsoleted by technological progress; since the "web safe" recommendations are often markedly different from the colours used in print, digital publications often attempt to approximate the printed colour. However, it has become common to specify colours for printing using the "Pantone Matching System", which is a proprietary colour space, and Pantone LLC prevents the publication of keys to their codes under intellectual property laws. The pdf document of the official "corporate design" manual published by the Federal Chancellery (2018 version) appears to be representing the red in the Swiss flag as RGB #e30613.[14] There are conflicting conventions in use among those canotons whose cantonal coats of arms have red tincture; Solothurn has specified "Pantone 032" since 1993, later followed suit by Bern and Schwyz, while Obwalden uses "Pantone 3G", and Basel-Landschaft, Nidwalden and Glarus have opted to issue no official recommendation.[15]


The ultimate origin of the white cross is attributed by three competing legends: To the Theban Legion, to the Reichssturmfahne (Imperial War Banner) attested from the 12th century, and to the Arma Christi that were especially venerated in the three forest cantons, and which they were allegedly allowed to display on the formerly uniformly red battle flag from 1289 by king Rudolph I of Habsburg at the occasion of a campaign to Besançon.

Use of a white cross as a mark of identification of the combined troops of the Old Swiss Confederacy is first attested in the Battle of Laupen (1339), where it was sewn on combatants' clothing as two stripes of textile, contrasting with the red St. George's cross of Habsburg Austria, and with the St. Andrew's cross used by Burgundy and Maximilian I. The first flag used as a field sign representing the confederacy rather than the individual cantons may have been used in the Battle of Arbedo in 1422 (notably without the participation of the Canton of Schwyz). This was a triangular red flag with an elongated white cross.

The white cross was thus in origin a field mark attached to combatants for identification, and later also to cantonal flags. The Lucerne chronicle of 1513, in battle scenes of the Burgundy wars of the 1470s shows cantonal flags with an added white cross. In this context, the solid-red war flag of Schwyz with the addition of the white cross appears much like the later flag of Switzerland. Other depictions in the illustrated chronicles show a flag of Schwyz with an asymmetrical white cross, drawn in greater detail. The symbol of the confederation as it developed during 1450-1520 was thus the white cross itself, not necessarily in a red field, but attached to existing flags, so that it appeared before a red background in those cantonal flags that contained red, notably the solid-red flag of Schwyz.

The first explicit mention of a separate flag representing the Confederacy dates to 1540, in the context of an auxiliary force sent by the Swiss to aid their associate, the city of Rottweil, in a feud against the lords of Landenberg. The Tagsatzung decided that the Swiss auxiliaries sent to Rottweil should receive "a red flag with a white upright cross". The first mention of the term Confederate Cross (Eidgenossen Crütz) dates to 1533.[16]

Because of the Swiss pledge of neutrality, there was no military conflict in which the Swiss confederate troops participated after 1540. Consequently, the confederate field sign fell out of use. At the same time, the former field sign develops into a representation of the Confederacy during this time, without achieving the full status as official heraldic emblem. The cross is shown as a symbol of the Swiss Confederacy on the Patenmedallie cast by Hans Jakob Stampfer and given by the Confederacy as a baptismal gift to Princess Claude of France in 1547. The cross appears on similar medals and on throughout the early modern period, but most symbolic depictions of the Confederacy in the 17th century do without the federal cross.

Beginning in the later 16th century, forces of the individual cantons adopted a type of flag which was based on a white cross design. These flags usually showed a white cross drawn to the edge of the field in front of a background striped in the respective cantonal colours. From this type, the flammé military flag develops in the 17th century, which also came to be used by Swiss mercenary regiments by the end of the 17th century. The flammé design remained popular for military flags of the 18th and 19th centuries. A flammé flag was introduced as ordonnance for the Bernese troops in 1703.

After the invasion of 1798, the authorities of the Helvetic Republic confiscated all earlier flags, replacing them with the new green-red-yellow tricolour. General Niklaus Franz von Bachmann used the white cross in a red field his campaigns of 1800 and 1815. The term Schweizer-Fahne (later spelling Schweizerfahne) is in use for the flag from this time, recorded in a poem on the Battle of Näfels by one J. Hottinger published in 1808.[17]

The Tagsatzung (Swiss Diet) re-introduced the white cross in the red field for the seal of the Confederacy in 1814. The commission for drafting a federal constitution on 16 May 1814 recommended the adoption of a seal of the Confederacy based on the "field sign of the old Swiss".[18] On 4 July 1815, the Diet accepted the design of the commission, adopted as the provisional seal described as "in the center, the federal red shield with the white cross as common federal heraldic emblem, surrounded by a simple circular Gothic ornament, on the outside of which the inscription 'Schweizerische Eidgenossenschaft' with the year number MDCCCXV, and in an outer circle all XXII cantonal coat of arms in circular fields, according to their federal order of precedence; around all, a simple wreath".[19]

This decision remained in force after the formation of the federal state in 1848, as was recognized by the Federal Council in 1889.[20] As opposed to the definition of an official seal or coat of arms, it was not, at the time, usual to specify a "national flag". However, the white cross in a red field had seen frequent use on flags flown by private organizations during the Regeneration period (1830s), especially shooting, singing and gymnastics associations which at the time were a pool for progressive or "radical" agitation. The canton of Aargau introduced the flag for its troops in 1833. General Guillaume-Henri Dufour proposed use of the flag for all federal forces in 1839. The Tagsatzung on 2 September 1839 passed a resolution prescribing the use of a unified flag design for all cantonal infantry regiments. In a first circular sent to the cantonal authorities, the flag was described as a red flag with a cross touching the edges, but in 1841, the Tagsatzung opted for a proposal by Carl Stauffer, which was announced to the cantons on 11 October 1841. The 1841 flag shows a bold cross suspended in the center of the square field. The proportions of the cross arm are 1:1, i.e. the cross is composed of five squares. The absolute width of the flag is given as 4.5 feet (105 cm), that of the cross as 3 feet (90 cm), for a ratio of cross to flag width of 2:3 ≈ 66.7% (as opposed to the modern 5:8 = 62.5%).

The specifications include the flag pole and the ribbon with the cantonal colours attached to the pole (the example depicted is the flag of the Zürich battalion). The flag itself is described as of good silk cloth, four feet five inches squared, scarlet, in the center a white cross, arms measuring one foot by three feet.

The Swiss constitution of 1848 did not name a national flag, but it prescribes the federal flag for all federal troops. The last flammé flags still used by Landwehr units were replaced by the modern design in 1865. In November 1889, the Federal Council published a "communication regarding the federal coat of arms", detailing the history of the use of the Swiss cross since the 15th century.[21]

Seals produced from 1815 onward, and cantonal coins minted from 1826 showed the arms of the cross in the 7:6 length to width ratio. Later in the 19th century, there was a trend of depicting the cross as composed of five equal squares. The two competing designs were controversially discussed in the late 19th century, especially after the introduction of the new design for the five franks coin, which showed the Swiss coat of arms in a Baroque-style heraldic shield. The Federal Council in 1889 introduced the 7:6 ratio as official. The associated communication explains that "our heraldic cross is not a mathematical figure, but at the same the Christian cross symbol and the field sign of the Old Confederacy". The 1889 law explicitly avoids specification of the shape of the shield, which was to be left to the "tastes of the current time and practical necessity".[2] The proposed legislation defining the Swiss federal coat of arms was passed on 12 December 1889 (SR 111).[22] The rectangular variant of the flag is used as a naval ensign only, officially introduced with a federal law passed 23 September 1953.

The current flag law of the Swiss Confederacy is the Wappenschutzgesetz (WSchG, SR 232.21) of 2013 (in force since 2017).[23] This law replaced the flag law 1931 (last revised 2008).[24] The 2013 law for the first time defines both the Swiss flag and the Swiss coat of arms based on an image, declared as authoritative in the text.[25]

Use in Switzerland

The flag is flown around the year from private and commercial buildings as a display of patriotism, particularly in rural areas and often together with the cantonal and municipal flag. On Swiss National Day, 1 August, the streets and buildings are traditionally festooned in celebration with Swiss flags and banners.

Prominent display of the Swiss flag on clothing and apparel has become more frequent with the "Swissness" fashion trend in the first decade of the 21st century, while such use of the flag had previously been largely limited to conservative and right-wing circles. The flag and coat of arms are also often used (frequently in contravention of federal law, see below) as design elements on merchandise, particularly on high-quality goods or on merchandise aimed at tourists; for example, the emblems of Victorinox and Wenger, manufacturers of Swiss Army knives and the sole purveyors of these knives to the Swiss army, are based on the Swiss coat of arms.

The display of the flag on federal, cantonal and municipal public buildings follows no uniform pattern or regulation. Many public buildings are equipped with flag posts (most often one each for the federal, cantonal and municipal flag), but the flag(s) may only be flown during part of the year or only on National Day. In Bern, the flag is flown on the cupola of the Federal Palace while the Federal Assembly is in session.

Destruction, removal or desecration of a Swiss, cantonal or municipal flag or coat of arms that has been installed by a public authority is punishable by a monetary penalty or imprisonment of up to three years according to the federal penal code.[26] The destruction or desecration of privately owned flags is legal.

The use of the Swiss flag or coat of arms on merchandise is technically prohibited by the 1931 Federal Act for the protection of public coats of arms and other public insignia,[27] but that prohibition is not enforced.


The Red Cross symbol used by the International Committee of the Red Cross, a red cross on white background, was the original protection symbol declared at the first Geneva Convention, the Convention for the Amelioration of the Condition of the Wounded in Armies in the Field of 1864. According to the ICRC the design was based on the Swiss flag by reversing of the colours of that flag, in order to honour Switzerland, where the first Geneva Convention was held, and its inventor and co-founder, the Swiss Henry Dunant.[28]

The modern banner of the Pontifical Swiss Guard was designed in 1912–14 by commander Jules Repond. The design has a Swiss cross design based on the 18th-century regimental flags of the Swiss Guards, with the papal coat of arms of the reigning pope in the upper hoist and the Della Rovere coat of arms of Julius II in the lower fly, and a vignette with the commander's coat of arms in the center.[29]

The club burgee of the Midland Sailing Club is the same design as the Swiss flag, apparently as the founder members thought that the club being based inland would be like the 'Swiss navy'.
