The dividing line lies at half the hoist, parallel to the upper and lower edges. With no emblem or border, the complete construction is determined by the 2:3 rectangle and the equal horizontal division.
Historical record
The red-and-white flag was raised at the proclamation of Indonesian independence on 17 August 1945. Article 35 of the Constitution identifies the national flag as Sang Merah Putih, while the 2009 law supplies its detailed form and rules of use.

Statutory proportions and screen colors
The recorded 2:3 (hoist:fly) proportions describe the statutory rectangle attributed to Article 4(1) of Law No. 24 of 2009, with equal horizontal halves, red above white.
The displayed #FF0000 and #FFFFFF values describe this page’s screen illustration. They should not be treated as established manufacturing standards or as evidence of customary manufacture. The cited geometry and band arrangement are distinct from digital color reproduction; the displayed values do not establish Pantone, textile or print specifications.
What the dates represent
The existing record’s 17 August 1945 date means “raised at the proclamation” of Indonesian independence. It is not presented here as an unqualified adoption date or an earliest-ever use claim. Law No. 24 of 2009 is the later legislation cited for detailed specifications.
Article 35 refers to the Constitution; the supplied source trail links to the 2009 law, rather than a separate constitutional text. The two law links are access points to the same legislation, not independent historical corroboration.
