Editing Flag of San Marino (section)

==Proportions and colours==
The official proportion of the flag is 3:4, the coat of arms' width being {{frac|3|8}} of the flag's length. While the arms are horizontally centered, their vertical position on the flag is defined by the location of the center of the cross on top of the crown: at {{frac|1|8}} of the flag's length. The proportion of the coat of arms is 5:6.<ref name="constitutional_law">{{cite web |url=http://www.consigliograndeegenerale.sm/on-line/Home/LavoriConsiliari/Dettaglidelleconvocazioni/documento17044527.html |title=BANDIERA E STEMMA UFFICIALE DELLA REPUBBLICA DI SAN MARINO |author=Consiglio Grande e Generale |date=22 July 2011 |website=Consiglio Grande e Generale |pages=3–4 |format=PDF |language=it |access-date= 29 September 2023}}</ref>
