What is the ratio of Paraguay's national flag? The ratio of Paraguay’s national flag is 11:20.

This proportion means the flag measures 11 units in height for every 20 units in length. It applies to the modern Paraguayan flag, whose red, white, and blue bands run horizontally across the field. The same proportion is used for both sides, even though the central emblems differ.

Paraguay’s design is often remembered for its unusual obverse and reverse. The front displays the national coat of arms, including a star and the words “República del Paraguay”; the reverse carries the treasury seal with a lion, a staff, and the motto “Paz y Justicia.”

The ratio can be confused with proportions used by other South American flags, including Argentina’s commonly listed 5:8 and Peru’s 2:3. Paraguay’s flag also changed in detail over time, and a 2013 revision restored elements associated with its earlier appearance, but the listed modern proportion remains 11:20.
